Looking fantastic as usual...

My latest headache is how I'm going to get a good finish on the main fueltank in the nose of the car. Most of the fibreglass I've painted so far has been to represent steelwork, now I'm trying to paint styrene to represent fibreglass!

There have been some interesting solutions to this problem discovered here, but my favorite thus far has been applying cloth of some type, or camera lens-cleaning paper over the fiberglass part before painting. The texture can look very convincing!

Test pieces underway tonight, Ian! I had thought about trying to drape the fine fibreglass cloth over the tank, but was worried that I might find things not-quite-fitting anymore! I've got a couple of pieces of 1oz and 2.3oz cloth glued to a piece of 0.5mm styrene sheet, so it'll be interesting to see how they turn out - if I can get the colour right afterwards we might be onto a winner!

Now wondering if priming and base-coating the tank was a good idea...

You know how sometimes you find yourself doing something you hadn't really expected to be doing? That's the story of the last few days!

Inspired / cajoled by ianc911, I glued a couple of pieces of fibreglass cloth to styrene, then added some colour to check the result:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1033_zps1o7njesc.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1033_zps1o7njesc.jpg.html)

1oz cloth on left, 2.3oz on the right. The weave is still visible through both, and the single layer only adds about 0.1mm to the thickness. The styrene started to distort a little due to the amount of glue, but I didn't think this would be a problem with the solid fuel tanks. So, time to start covering.

I started with the upper wedge from the main fuel tank - I reckoned that if anything went drastically wrong, this piece would be easiest to re-make. That's confidence for you...

I used the heavier 2.3oz cloth; the lighter stuff is so easily snagged, distorted and generally messed up by handling that I needed the stability of the 2.3oz. Problem number two was the need to cut holes in the cloth to fit around the openings for the filler necks, etc. Fortunately I'd kept the pieces of styrene cut from the original panels used to make the tanks, so could use these as templates. I tried using a piece of masking tape to stabilise the cloth during cutting - it made it easier to cut the hole, but pulled the cloth to shreds when removed! So, cut the hole, give the tank a rub over with emery cloth to break up the layers of paint and primer, then add plenty of liquid-poly glue:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1034_zpsdvmqrvn2.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1034_zpsdvmqrvn2.jpg.html)

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1035_zps0pvnepha.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1035_zps0pvnepha.jpg.html)

As per the tutorial, more glue was added after the cloth was in place. It was obvious very quickly that the technique was sound - if a little messy, as you can see from the state of my fingertips!

After completing the wedge, I continued with the collector tank - a more complicated shape:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1036_zpsrr2k1vdi.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1036_zpsrr2k1vdi.jpg.html)

It wasn't necessary to completely cover each tank, as some sections would be hidden from view when the parts were fitted into the car. A few spots of CA glue were used to make sure things stayed stuck - particularly in places where two layers of cloth were overlapping.

Finally, the main fuel tank:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1037_zpssmtj33ri.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1037_zpssmtj33ri.jpg.html)

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1038_zpsa46c9etd.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1038_zpsa46c9etd.jpg.html)

Remember how I was questioning whether it was a good idea to prime and paint the tank parts in the earlier post? Absolutely a good idea! The combination of bare styrene, grey primer and sand-yellow base-coat, mixed together with the liquid-poly glue makes for a great undercoat showing through the cloth.

I then gave the parts a scrubbing-over with 'Snakebite Leather':

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1039_zpstk2zmicv.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1039_zpstk2zmicv.jpg.html)

...and then a little 'Vomit Brown' and 'Kommando Khaki' to tone things down a little:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1040_zpspvyp4e2z.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1040_zpspvyp4e2z.jpg.html)

Not finished yet, but I'm really pleased with the result so far. I might try a thin wash to bring the weave out more - it's more noticeable in reality than in the photos. The openings need painting, the bolt detailing picking out, etc, plus I need to finish making the filler mechanisms, so there's plenty still to do.

So, I hadn't expected to spend most of yesterday gluing fibreglass cloth to my fuel tank sections...but I'm glad I did. Cheers, Ianc!

Glad it worked out for you; looks really good to me and gobs better than flat styrene. I like the color as well; I remember it took me a good bit of finagling to come up with the proper mix of Tamiya paints to simulate the ocher fiberglass color.

A new tool in your chest!

Back again!

Work continues with getting everything ready for fitting the main bulkhead / firewall, and the roll-cage. The following photos are a little out of sequence but I wanted to get somewhere close to up-to-date for the start of my holiday.

First up, here's a better view of how things are looking overall. All the front panelling has been painted, but the sides have also been glued in place since the photo was taken. This has also required the exit ducting for the rads to be fitted too:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1041_zpst8xnjbnr.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1041_zpst8xnjbnr.jpg.html)

The interior panels forming the rear firewall have also been fitted, leaving small gaps in between. I used the Liquid Greenstuff to take care of the filling, but knew that some re-painting would be required. Initially I thought it would be necessary to mask-off the interior and get the airbrush out again, but some careful brushwork managed to get the job done.

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1042_zpstpwlhib4.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1042_zpstpwlhib4.jpg.html)

...and after:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1043_zpsycgqdur8.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1043_zpsycgqdur8.jpg.html)

Please excuse the dust! In these last two photos you can also see where I've added a length of thin strip to the door opening each side - this will eventually extend all around the doorframe, and form the doorseal. It also gives me a neat divide between the black interior and the white exterior.

Down in the footwell, I test-fitted the fire-bottles and pedals to make sure that the upper bulkhead could still be fitted afterwards: it can. I've done the final few bits of detail painting on the pedal assembly, so this is all ready to go in whenever I want. The fire-bottles need labelling before assembly - I've got some photos ready, and will be working on these during the next week or so. If I can persuade the aluminium parts of the mounting cradle to stay glued together, that would be even better!

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1045_zpsrl4ylxpn.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1045_zpsrl4ylxpn.jpg.html)

Over on the left-hand side you can see where I've added a seam of greenstuff around the mounting pedestal for the roll-cage. While this was going off I temporarily fitted the roof, etc, to make sure the front wheelarch panels were in the right place. Also in this shot there are a few of the sections of fibreglass strapping added over the bottom tubes in various places.

Next, a small diversion. Each side of the roll-cage there is a small bracket which will bolt the tube-frame to the remains of the 911 shell - here's the left-hand side. They won't be structural on this car - they'll just disappear into the wheelarch panel interior:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1046_zpsrtyriktl.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1046_zpsrtyriktl.jpg.html)

Finally, I decided it was time to start painting the gearbox. I double-checked the reference photos to make sure I hadn't missed something, added a couple of hex-plug details, drilled out a hole for one of the oil fittings, and added a coat of Tamiya grey primer:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1047_zpstkgtkuag.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1047_zpstkgtkuag.jpg.html)

I'll give it a coat of flat black with the airbrush tomorrow, then gradually drybrush the final layers by hand, much the same as with the engine, etc.

Two other things before I finish tonight. Earlier this afternoon I started laying up two versions of the cover panel which will close-off the hole in the cockpit ahead of the gearbox. While doing this, I've added a layer of cloth to the top of the roof - some of the filler was cracking, so I wanted to tie it all together and effectively start again. It'll need more filler and sanding, but it should work. You'll see both of these in the next update.

More next time.

Hi Ian,

I'm not sure that 'can't wait' is how I'd describe it! More like 'can't wait until it's over'. I probably said much the same thing when I was doing the 908-03: whether you have reference info or not, it's still difficult to get things looking 'right'. I'm planning to spend a good few hours poring over all my reference photos trying to piece together what goes where - I suspect the 917 wiring diagram in 'The Undercover Story' might also give me a few ideas.

One benefit of the 935 compared to the 908 is that much of the wiring behind the dashboard will be hidden from view, so there's room for a little creative freedom. Mind you, there's still a lot of stuff running back towards the engine bay - fuel and brake lines, all the gauge feeds, extinguisher lines, etc - so the cockpit will start getting busy.

Fortunately I managed to get my head around the oil, water and fuel systems some time ago, so at least some of the pipework and plumbing is (sort of) under control!

We'll see how things work out...

Hello again,

So, have I had a productive two weeks? The answer has to be yes - I haven't reached the stage where I could fit the front bulkhead and firewall panels in place, but my work on understanding the wiring is definitely paying off.

I started by spending most of an afternoon scrutinising the 917 wiring diagram in Wingrove's 'The Undercover Story', and trying to relate it to what I could see in the 935 reference photos. I ended up with a bunch of main components, a list of connections and wire colours, and the hope that I might actually be able to get this all looking vaguely accurate:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1048_zpsej6egzqq.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1048_zpsej6egzqq.jpg.html)

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1049_zpspwbwb8hi.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1049_zpspwbwb8hi.jpg.html)

As well as using various grades of wire bought from the high-street, I'm using a lot of pre-coloured wire from Hiroboy - this was part of my prize from winning AFMOTY with the 908-03, so it's been sitting around for a few years waiting for the right time! The larger high-street wire is stripped out to act as sheathing, and the 0.4mm Hiroboy wire is used for the detailing.

A lot of the wires connect to a couple of fuseboxes, so for these I've made some small spade terminals from 0.75 x 1.5mm strip:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1050_zpsfxzyzuxp.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1050_zpsfxzyzuxp.jpg.html)

So far, it looks like this:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1056_zpska5rmnym.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1056_zpska5rmnym.jpg.html)

It's a bit of a mess, but I need to get this section sorted out before assembling the bulkhead panel and firewall. The larger black wires on the left will run forwards to the battery and nose lights or back into the engine bay, some of the loose wires on the right will disappear into the instrument pod, and a few more will connect to the switches and gauge on the lower part of the dashboard. It's a long way from being finished, but it's the sort of job that only works if I can hit it hard for several hours a day, over a few days. Now it's underway I can continue adding to it during the normal weekday evenings, without feeling that I'm not getting anywhere!

While working on the wiring, I've also started on some the other components - switches, warning lights, battery cut-offs, etc. Here's the back of the gauges on the lower instrument panel - they'll be visible through the doorways so have to be properly detailed with wiring and sender lines:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1052_zpsqlgnxr6y.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1052_zpsqlgnxr6y.jpg.html)

Another key job for the holiday was to sort out the decals on the two fire-bottles - until these are done, I can't assemble the bottles into the mountings. I couldn't find image scans of the correct Heinzmann labels online, so had to take photos of photos (don't ask!) and fiddle around with Photoshop. Here are the results:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1053_zps0jb5qguu.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1053_zps0jb5qguu.jpg.html)

To give you an idea of scale, the main labels are about 27mm long. It's been five years since I did the 908 decals, but it all worked out okay - here's the two bottles:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1054_zpskgsljiy5.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1054_zpskgsljiy5.jpg.html)

I was worried that the little ridge around the bottle might cause problems, but a good dose of MicroSet / MicroSol did the trick. A spray coat of gloss varnish afterwards has hopefully given them some long-term protection.

Amongst all this I've been painting the gearbox, working through the layers of drybrushing:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1058_zpsjkyrb6yf.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1058_zpsjkyrb6yf.jpg.html)

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1057_zpssufbomza.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1057_zpssufbomza.jpg.html)

It looks better in reality than in the photos, I feel. There's a little tidying to be done around the hex detailing, and the clutch lever, starter motor, etc, all have to be added.

Also in gearbox mode, here's the fibreglass cover panel I started making two weeks ago - trimmed up and in position:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1055_zpsiorfe2bt.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1055_zpsiorfe2bt.jpg.html)

There won't be too much of the gearbox visible when it's all complete, but it will be too difficult to have these panels removable. One of the problems of having a roof on the car, I suppose!

So, lots to be working on between now and Christmas. Can I get the cockpit wiring sorted out so that I can go into 2017 with an assembled firewall and bulkhead? That's the new plan. I'll also be finding suitable images to make decals for the battery, making a few more electrical system components (spark box for the rear parcel-shelf, etc), probably painting a few components, and generally moving around from one thing to another!

As always, have a good week.

I can't believe I haven't posted since the start of December! A late 'Happy New Year' to you all, of course.

Why the silence? Not for lack of progress, certainly. Although I made a good start on sorting out the under-dashboard wiring during my November holiday, I struggled to continue with it afterwards - rather than force things, I put it to one side. I still wanted to move towards being able to assemble the front bulkhead / firewall, but found various other things to divert me...

First up, in mid-December I received a small package from Rijk in Holland - you might remember he made the suspension springs for the 908-03. He offered to make more for the 935, and I was happy to accept! So, I spent several evenings playing around with various combinations of springs, making locator collars, etc. Here are the rears:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1059_zpsa9hdqiam.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1059_zpsa9hdqiam.jpg.html)

...and one of the fronts:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1060_zpsaj0e6uvg.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1060_zpsaj0e6uvg.jpg.html)

I asked Rijk if he could make the main springs and some smaller 'helper' springs - the originals appear to be a single variable-rate spring, but I couldn't see how this could be replicated in scale. I'm very happy with the results, and they look much better than anything I could have made - thanks, Rijk!

Another job to be tackled before assembly was to paint some of the gauges and switches that would be fitted into the lower dashboard panel. I taped everything to a piece of card and set-to:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1061_zpsmfi3ldca.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1061_zpsmfi3ldca.jpg.html)

The gauges were filled with the 'liquid water' afterwards to create the effect of a glass face, and everything was glued in position. One thing I still need to do is to add the small ignition key detail to the switch...

The next couple of photos were taken during the Christmas holiday period. I fitted the two fire bottles into the mounting cradle, and wanted to make the hard extinguisher lines that were routed around the cockpit and the engine bay. I used more of the 1.2mm plastic-coated wire, and started bending:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1062_zpskwy4r51y.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1062_zpskwy4r51y.jpg.html)

The bottle will connect to the hard-line with a short length of flexible hose under the bulkhead. It follows the bottom of the instrument panel then runs up the inside of the door pillar, along the roll-cage and behind the driver. And yes, those are some very small 1/8-scale P-clips I made to attach it...

It's a similar story in the engine bay:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1063_zps1ev0mnfu.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1063_zps1ev0mnfu.jpg.html)

Moving on, the wiring under the bulkhead slowly fell into place - I couldn't avoid it, after all. I added some pieces of small-diameter heat-shrink for variety, and tried to route the cables so that it all looked appropriately busy (while still being based partly on the 917's wiring...)

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1065_zpsspajehv2.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1065_zpsspajehv2.jpg.html)

The red T-handle for the fire system is a recent addition, as is the control box on the left-hand side. Next, I fitted the firing mechanism for the larger of the two fire bottles - having checked to make sure the bulkhead panel would still fit:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1066_zpsi6dsvmtd.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1066_zpsi6dsvmtd.jpg.html)

Some finishing touches for the pedal assembly: the blue hoses will connect to the two remote-mounted fluid reservoirs, and I've added two splitter-fittings to the master cylinder outlets. The right-hand cylinder will have two lines running to the front brakes, and the left-hand cylinder has a fitting to activate the brake lights, and a single line running to the rear brakes (there'll be a T-piece at the back of the cockpit):

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1067_zps1zivryhv.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1067_zps1zivryhv.jpg.html)

Finally for tonight, here's what it all looks like when viewed through the open doorway:

The fun part, of course, will be connecting the brake light line and fire-pulls once the whole lot is glued in place. No coffee that night, I think...

I should also mention that in amongst all these jobs I fitted the main roll-cage, attached the rear bulkhead, fitted the front lower bulkhead (having threaded one of the water pipes through first), and have fixed the two supporting straps where the top part of the cage meets the engine bay. There's been plenty of greenstuff applied in various places to fill gaps, and it's all been painted-in to suit. Like I said - it's not a lack of progress, more a lack of decent photos!

That's it for now. I'm running out of things to do before the front bulkhead goes in, so it shouldn't be too long before that major hurdle is cleared - this will allow all sorts of other parts to be fitted. I also want to make some small decals to label all the instruments (in German, of course...), so that's another little diversion.

Have a good week,

SB

Thanks, folks - hopefully the next few weeks will see some major developments as things start falling into place...

Just three photos tonight, but real progress. This last weekend was finally time for fitting the front firewall / bulkhead. I was somewhat inspired by knowing I would be watching coverage of the Daytona 24h, and so I could have a really good modelling session. Since the last update I've been trying to get all the little jobs out of the way - anything under, on, or through the firewall that would be awkward to do once it was fitted:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1068_zpsfktzx2bb.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1068_zpsfktzx2bb.jpg.html)

I've routed two solid brake lines through to the front, and one to the rear - this will split at the back of the cockpit before going out to each corner. I used 0.9mm lead wire for these (making it easier to create the shape) with 1.2mm heatshrink as a protective sleeve. The two front lines need extra detailing where they fix to the chassis, but this can be done later. The green cables will connect to each end of the front roll-bar. The larger black hose at bottom-left is the oil-cooler bypass pipe to the tank. After taking this photo I added a small temperature sender fitting to the main chassis rail next to the bypass pipe, to connect to one of the water temperature gauges.

The two blue hoses onto the brake master cylinders have been re-made since the last update, as the originals were too stiff and were going to put too much pressure on the reservoirs. The new ones have had all the individual wiring strands removed, and a single piece of thin wire added to keep the shape.

Fast-forward to the weekend, and here's the dashboard / firewall in place. I added the decals for some of the gauges and switches last weekend, then sprayed the whole panel with some Games Workshop 'Ardcoat' gloss varnish before fitting. The auxiliary gauge panel which hangs below has also been labelled and sprayed, and will hopefully be fitted this week. I made another small test-piece gauge with the 'water texture' glass and varnished this first, just in case of a reaction...

The ignition barrel has had a small key fitted, including key-ring! Might not be technically correct, but it seemed a fun little detail to add. I added a few small hex-nut fittings across the top of the gauge panel, and a couple either side of the dashboard master-switch. The main instrument pod and steering column will be fitted later.

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1069_zps7rkfxbyp.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1069_zps7rkfxbyp.jpg.html)




Here's the view from the other side:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1070_zpsxza7igvy.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1070_zpsxza7igvy.jpg.html)

The tricky part during assembly was getting all the wires and cables threaded through the panel - it meant I had to glue the panel after fitting, not during. The roll-bar cables and master cylinder lines have been trimmed a little just to tidy things up - they won't be connected to anything just yet. I've got a bunch of cables snaking down the right-hand side which will connect to the front lights, and there'll be more cabling to add once the battery, fuel pumps, washer bottle, etc, are added. Now the panel is in, it's opened up lots of other jobs to do - the thing that's going to slow me down will be the rate at which I can (spray) paint parts.

More next time.

More progress from the front end tonight, folks.

As usual, it's all the tiny fiddly things that take all the time, but leave you feeling like you've not done anything! For example, here's a view of the steering rack and front bulkhead area:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1074_zpsjmu2hjtz.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1074_zpsjmu2hjtz.jpg.html)

The hard front brake lines now connect to a pair of fittings attached to the chassis, with a length of flexible pipe available to run out to each caliper. Making these fittings was several evening's work, plus the painting and assembly onto the frame. The front lower wishbones have now been fixed - had to make four pins with hex-nut detailing each end.

Big news - the front adjustable roll-bar is now fitted. This was another couple of evenings spent drilling holes in the side panels, fitting the mounting blocks, adding some stop-collars to the bar, painting and final assembly. The green adjuster cables have been trimmed to length and glued in place.

Amongst all this, I've also been doing a little painting:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1071_zpsgvcb7ctg.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1071_zpsgvcb7ctg.jpg.html)

Rear trailing arms, airjacks and the steering column surround - all airbrushed. I'll build up some more colour by hand, over time. Next, the front uprights and lower struts:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1072_zpss4vs3p5e.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1072_zpss4vs3p5e.jpg.html)

At the moment this is a combination of Citadel 'Graveyard Earth' over an airbrushed coat of Tamiya 'Titanium Silver', but they have a way to go.

Finally, I've also started painting the brake discs - here's the four disc bells (again, Titanium Silver):

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1073_zpsddskq7wq.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1073_zpsddskq7wq.jpg.html)

This is all very much 'work in progress', but it keeps things moving along.

To finish, here's a couple of up-to-date photos of the front end (taken tonight as the originals were poor-quality!):

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1075_zpsvaskkjcm.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1075_zpsvaskkjcm.jpg.html)

The steering rack is now fixed, and I've spent some time playing around with the rack bar and trackrods to get the front geometry just-so. The only adjustment is in the length of the rack bar, so I'll make the final decision on this only when I have the suspension properly fitted; it's been dummied-up a few times, but this is never the same as final assembly!

The two fibreglass closing panels have been added either side of the rack, as have the two small curving panels behind the front leg of the lower wishbones. As long as I don't fit the main fuel tank first, I can still access the rack to adjust the bar length, and glue in the trackrods.

In this view, the three fuel pumps are now glued in place, and I've trimmed the pipework to length. The two universal joints in the steering column are fixed, and I've added the short stay which connects the top of the bulkhead / firewall to the chassis. The oil catch-tank has been painted, but not permanently fitted yet:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1076_zpszoklc6a6.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1076_zpszoklc6a6.jpg.html)

What else? The main gauges have been painted and are now receiving their 'Water Texture' glasses - I'm hoping to have these fitted into the instrument pod during the next few days. I've been painting the various oil and fuel-line fittings for the front of the car, so will probably have a plumbing session soon and trim everything to length. The lower instrument panel has been wired-up and just needs to be fitted in place - possibly a job for this week.

I'll probably spend another week or so working on the front of the car, then shift my attention to the engine bay for a while. There's plenty of things to do in there - painting, detailing, assembly, etc - and it feels like I've been concentrating on the front for a looong time. 'A change is as good as a rest', I think they say!

Have a good week,

SB

Not a big update tonight, but I wanted to get this photo posted immediately:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1077_zpsbvwmsjbb.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1077_zpsbvwmsjbb.jpg.html)

The obvious progress is the main instrument pod. During this week I've been fitting the dials, adding the warning lights and extra switches, and a few decals. It's ready to be glued in place.

In addition, I've fitted the solid cockpit fire extinguisher line. I'm pleased with this - the silver makes a good frame for the black dashboard and instrument pod, and it didn't fight me too much when I fitted it! The awkward part was connecting it to the flexible line from the fire-bottle...

Finally, the lower instrument panel has been fitted ahead of the gearshift tower. This could only go in after the extinguisher line. The temperature and pressure sender wires have been routed along the chassis tubes each side and run through into the engine bay. I've tied them in place with very thin wire - I've got some MFH scale ty-wraps which I've yet to use, so these could make an appearance soon.

So, only one photo, but the cockpit is now looking very 935!

A few more photos for tonight's update.

As I mentioned a couple of posts ago, my enthusiasm for working at the front of the car has finally started to run out, so one of my last jobs in this area (for now - I will return!) was to do a test-fit of the gear linkage:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1078_zpszyescarp.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1078_zpszyescarp.jpg.html)

The boost-control knob has been fitted and plumbed-in, with two lines running back towards the engine bay. The main rod in the shift-linkage has been trimmed short and I've been checking that the whole lot can be assembled once the fibreglass cover panel is fitted over the front of the gearbox. There's enough slack in the system that even with the main gear-lever fixed in place, I can wriggle the rear section through the cover and connect the two ends together. This all needs final assembly, but it's now the correct length.

Next, I returned to work in the engine bay. Although I made the main turbo components a while ago (end of 2015?) there's still lots of little details required - lubrication and control pipework, fixings, etc. The next couple of photos show a selection of these parts:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1079_zps8e3lwadk.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1079_zps8e3lwadk.jpg.html)

Here's two of the main turbo sections, now with added styrene nut detailing and some tiny P-clips - these will hold some lead-wire cables to be added later. The various fittings will be used to connect the pipework running from...

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1080_zpsg9j3purq.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1080_zpsg9j3purq.jpg.html)

...the two parts on the left of this photo! The small block on the right is an external oil pump which will attach to the front of the engine, and connects to the two fittings on the bottom of the other two parts. I've been doing some trimming on the fibreglass engine mounting plate, to allow this extra pump to sit where it needs to go:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1081_zpszhwi8btr.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1081_zpszhwi8btr.jpg.html)

Finally for tonight, I've had another primer session:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1084_zpsizedk0tp.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1084_zpsizedk0tp.jpg.html)

I've now got all the main turbo parts primered (a few not shown here) except for the main exhaust primaries, and the engine mounting plate. Some of the above will be brush-painted, some will probably be air-brushed (depending on how I want the final texture). I might add some textured paste to the two connecting tubes for the turbo - must check the reference photos again. Getting this lot painted and assembled should keep me busy for a couple of weeks!

Once this is done, I've still got the throttle linkage to finalise, fuel pump, water pump, etc, drive-belts, finish the water system, paint the cam covers...oh, and to actually finish assembling the whole engine! I'm sure there will still be some more pipe-fittings to make, too...

Current weight of the main chassis, complete with the fuel tanks in the nose, is about 0.6kg. No engine, gearbox, suspension, bodywork, etc. I can't remember what the 908-03 weighed-in at, but I guess the 935 will comfortably be over 1kg. Closer to 2kg, though? We'll see!

All the best,

SB

The last couple of weeks or so since the previous update have mainly been spent painting a variety of components, all with the aim of eventually being able to assemble more of the engine. While doing this I'm finding small little things I need to re-visit or modify slightly, so nothing is ever straight-forward!

Before I could paint the main engine / turbo mounting plate, I had to add a towing eye hoop to the bottom:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1085_zpsxdkynpmq.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1085_zpsxdkynpmq.jpg.html)

...and here's some painted parts:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1086_zpsj6nrxz7t.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1086_zpsj6nrxz7t.jpg.html)

Engine plate, turbo parts, and a cover for the fan drive-pulley. My painting method is becoming a mixture of airbrush and hand-brushing, depending on what sort of final 'texture' I'm trying to achieve. There are a lot of components on this car that are not perfectly smooth, and drybrushing still works well to bring that out.

More parts:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1087_zpsu88noor2.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1087_zpsu88noor2.jpg.html)

The turbo-intercooler connecting pipes were given a coating of Citadel 'Astrogranite' textured paint - it doesn't seem to be quite so thick as the 'sandy paste' used for the intercoolers themselves. The other parts have been dry-brushed over a primer base-coat and are pretty much ready for assembly.

And more:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1088_zpsjqvpj7s9.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1088_zpsjqvpj7s9.jpg.html)

These are not quite ready for assembly. I'm particularly pleased with the small piece of mesh in the tops of the two control valves, now that it's had some black paint run in to give it some contrast.

Finally for tonight, I've painted the engine cam-covers:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1089_zpsbuqab6dd.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1089_zpsbuqab6dd.jpg.html)

I've left these until now as I know they'll get a lot of handling until the engine is finally in the car, so the paintwork could easily suffer. They were grey-primered, then two airbrush coats of Tamiya 'Flat Black', then the main colour drybrushed in about five different layers. Once they're on the engine I'll spray the whole lot with some matt varnish to (hopefully) give it some protection.

So, what else is in progress? I've got the starter motor in base-coat, the water pumps for the head-cooling are ready for undercoating and painting, and there's a bunch of other engine-related parts that need to be painted (distributor cap, plugs and retainers, throttle mechanism, etc). Eventually I might even start gluing some of this together...

Have a good week,

SB

Sorry that the updates have been a little irregular recently - it's not for a lack of progress!

Since last time I've been pushing forward with getting the engine assembled - always a nervous time as you're 'passing the point of no return' with every component that is glued in place! I'm always surprised at all the little bits that fitted perfectly six months ago, but don't quite fit when you do the final assembly. So there's little adjustments to make here and there, but so far it's going okay.

I should have three extra photos here tonight, but they seem to have vanished somewhere between my PC and arriving in Photobucket. No problem - the five that remain should give you an idea of what I've been doing.

First up, the cylinder heads and cam-boxes are now glued in place. This meant that I could (re)make and fit the lower panels, and add some final detailing around the outside edge:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1091_zpshadn93qx.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1091_zpshadn93qx.jpg.html)

This has all been undercoated and painted to match the upper parts. Once these main sections were in place, I could add the little closing panels at the front of the engine, then fit the lower water rails and the head-cooling water pumps:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1092_zpsgjacfixn.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1092_zpsgjacfixn.jpg.html)

The short pieces of 'water hose' are styrene tube with hose-clip detailing added, and do a great job of hiding the joint between the pumps and rails. Before I went further I sprayed the whole lot with Citadel 'Purity Seal' varnish - not a gloss varnish, but I wouldn't describe it as matt, either. I'm trying not to handle the engine too much (not easy) so there's bound to be more bits of paintwork that need minor repairs later on...

Next stage, detailing! I made the diz cap, spark plugs, retainers, etc, months ago, so these have all now been painted (as you'll see below). I've been putting off making the fuel injectors for some time as it's one of those fiddly jobs that isn't particularly fun, but I couldn't avoid them any more! Here's what I ended up with:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1095_zpsta2qllni.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1095_zpsta2qllni.jpg.html)

The wire used for the fuel lines is from a telephone exchange box under the pavement, near my home. They're installing some new broadband cabinets and the guys doing the work were ripping out huge bundles of old-school wiring, in all sorts of colours. My parents stopped by during a walk around the village, knew that I would find a use for it, and came home with enough to keep me wiring-up cars for several years to come!

So, when you've got all these bits it's a shame not to fit them, right? Here's the left-hand side:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1097_zpsuouzx2ot.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1097_zpsuouzx2ot.jpg.html)

The orange-red of the diz cap introduces a shot of colour to the overall brown / grey tone of the engine - I couldn't resist adding the little yellow indicator marks for the plug leads, too. All six leads were test-fitted, trimmed to approximate length, glued to the diz, routed appropriately, then final-fixed. I've added one or two little retainer clips each side to keep things tidy.

In this photo you can also see that I finished making the two little oil pumps which fit on the end of the lower cam-boxes - if I can work out exactly where the oil feeds go to, I will be very happy! Of course, the two inlet stacks have also been fitted, too.

The three leads for the other side snake around the back of the cooling fan
- some of the reference photos have them going over the top of the fan at the front, others have the routing I'm using:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1096_zpsr2ubdgb6.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1096_zpsr2ubdgb6.jpg.html)

This shot gives a better view of the spark-plug retainer clips, too. The fuel-injection pump assembly has also been fitted - before I could do this I had to paint and fit the connecting linkage which runs up to the main throttle lever, and add the small pipe which comes out the top of the cam-box. At this stage three of the fuel lines have been trimmed to length and glued in place (with end-fitting detailing), the other three are to follow.

The cover for the fuel injection drive pulley at the front end does a good job of providing extra security to the pump itself - although the lower connection needed a little modification for a better fit into the cam-box socket.

So, major progress. My working pattern has been a bit disrupted recently, as I've been making new bits, painting them, modding old bits, painting old bits, assembling, dis-assembling, etc, all at the same time! In amongst all this I've primed and base-coated all the main driveshaft components, so that's another painting and assembly session to come sometime, and I've also started painting the throttle linkage bits - now the inlet stacks are fixed, I can finalise the length of the throttle cross-tube. I'm also returning to the end-tank detailing on the main intercoolers, as you'll probably see next time.

See you soon,

You know....in a few years time, when this is finished SB (please don't let it end...), people gonna look at it and say "nice model"............... :)

But seeing it evolve I relate to watching a magic trick exposed.
The finer details you miss while the trick is being performed, it all falls into place when you see how it is done. I LOVE seeing that kind of stuff.

Thanks, Stump. I don't think there's any danger of this project being finished this year, but I'd like to have it complete during 2018 - just in time for Moby Dick's 40th birthday! It's quite satisfying at this stage to see the boxes of parts made during the last few years slowly start to empty as more things are assembled - the problem is often remembering how certain things were intended to go together - "why did I do that like that?".

There's also a growing sense of relief at this point that everything is actually coming together: it's all fitting, it's all working. Yes, there are still a few major obstacles ahead - I'm still not looking forward to doing the Martini stripes - but the core car underneath is technically plausible.

And for tonight....

Most of last week was spent putting together the throttle lever mechanism and fitting the intercoolers to the tops of the inlet stacks. Although there wasn't too much to actually make at this point, there was still plenty of adjustment and final detailing required as the mechanism was assembled. Here's how it looks:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1099_zpsqc148kl3.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1099_zpsqc148kl3.jpg.html)

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1100_zpsosix3sqw.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1100_zpsosix3sqw.jpg.html)

It's a tight fit in the chassis, but it works! The only thing missing now is the throttle cable - this will connect to the lever arm in the middle (above the fan). Although it's lying flat now, this section is still able to pivot on the main shaft, so that I can adjust the angle with the cable.

I've also added two support rods between the two intercoolers. I'd seen these on some of the reference photos, but couldn't work out exactly what they were - but it just clicked into place. It made sense to have an extra support for the intercoolers, rather than having all the weight cantilevered from the inlet stacks. So, it was easy enough to make two stays, drill the intercoolers to pin them in place, and put two small holes in the fibreglass fan shroud for the bottom ends to poke through.

The next job has occupied this last week: making the water pipes to connect the two intercoolers together. These have an aluminium tube core, 4mm styrene tube over the top (in thin sections at the bends), with greenstuff to fill in the gaps:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1101_zpsbxii69uq.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1101_zpsbxii69uq.jpg.html)

Of course, I couldn't make them as a single piece - they were made in sections, then fitted together. Before adding the 'Astrogranite' textured paint to create the hose sections, I wrapped 2mm x 0.3mm strip around to make the hoseclip detailing, with 1mm Wave hex-nuts.

The ends of the intercoolers could now be fitted, with the two pipe sections in between:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1102_zps6v1lffad.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1102_zps6v1lffad.jpg.html)

The upper section is still able to pivot, so I've got a little flexibility with the final pipework back to the chassis frame. The black pipe with the hex ends is some sort of balancing system between the two sets of inlet stacks.

So, all I have to do now is to add the two short pipes which take the intercooler water back into the chassis frame - that's a job for later. First job for next week is to add the water pump drive pulleys and belt, then I need to add a couple of bits of plumbing to the front of the engine before I forget! I still want to add an extra support somehow, but I'm now concerned that the intercooler pipes above will be right in the way. We'll see. Another item on the 'to-do' list for next week is to start refining the pipework for the two side radiators.

That's it for tonight. It's a busy few weeks coming up - Nurburgring 24 next weekend, then Le Mans Test day, then the 24 Heures itself. Fantastic! I should be able to get a couple of updates posted before the big weekend...

Hello again,

So, I've been spending a lot of time recently trying to finish off the various bits of pipework for the cooling circuits. With the intercooler plumbing sorted out last time, I returned to the head-cooling pipes (which I'd started some time ago).

Access wasn't easy with the engine in place, so I used my normal technique of breaking the pipes into smaller sections, bending a wire core, and adding slices of styrene tube to suit:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1103_zps9kw0nprb.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1103_zps9kw0nprb.jpg.html)

The main pipes running from the side radiators were trimmed to length after passing through the rear bulkhead, and the new pipes drop down to the top of the engine and the two lower water pumps. Here's the left-hand side:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1107_zpskrr1rt2w.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1107_zpskrr1rt2w.jpg.html)

...and here's the right:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1106_zpspmrknlnn.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1106_zpspmrknlnn.jpg.html)

The final fitting of all this pipework is going to be a pain, I can feel it! I've made eight more hose sections from larger styrene tube, complete with hose-clip detailing, and these will slip over the pipes and hide all the joints, so there's a little room for misalignment.

Also visible in this photo is the new pipe which connects the intercooler system to the chassis tube, and so to the cooler at the front of the car. There's something similar on the left-hand side, to the water pump, but it's hidden behind the chassis panelling. Both of these pipes can only be fixed in place once the engine / gearbox assembly is fitted, of course...

Two more things tonight. I wanted to finalise the attachment points for the clutch and throttle cable, but was struggling with reference material. I found a couple of shots showing the clutch cable slotted into a web on the top of the gearbox, so that was the starting point. The throttle cable (or cables, as photos clearly showed a spare was pre-installed for racing) was a mystery, though. My first thought was to mount them to the underside of the water header tank, but (a) this didn't seem very Porsche-like and (b) from what I could see of the cables they're pulling from low down, not higher up.

So, I added a simple bracket to the top of the new gearbox web for the clutch cable:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1104_zpsmkjuudih.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1104_zpsmkjuudih.jpg.html)

It's possible that the cables could be mounted off the top of the engine breather cover, but I have nothing to confirm this. My version is plausible, and that's good enough for me!

In the background of the photo above you can also see the two pulleys and belt detailing for the intercooler water pump.

Finally for tonight, I've started making the mounting plate which supports the front of the gearbox:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1105_zpskdgg4rmx.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1105_zpskdgg4rmx.jpg.html)

Although I used 0.75mm styrene for this, I added a lower layer of fibreglass sheet to give it some extra stiffness. It's been drilled and pinned to the front of the gearbox, as shown, and will eventually have some large bolt details added to connect it to the chassis brackets.

The amount of pipework at the front of the engine is giving me major problems in how I can add some extra support to the engine / gearbox mounting. Everywhere I want to run a length of wire up to the chassis, there's a pipe in the way! I'll have to spend some time looking at the options, as I'd like to avoid having a permanent support under the engine.

As usual, there's still plenty to do. The drivetrain won't be going in permanently any time soon, but there's still more detailing to be added in the back of the engine bay, plus wiring and plumbing to be brought through. I think there's still a few weeks work on all this before I consider moving my attention to a different part of the car...

Back again!

I've been planning to do another update for the last couple of weeks, but every time I've thought 'I'll just do a bit more' and have continued modelling, rather than posting! My trip to Le Mans last month brought the usual mixed feelings - part of me returns home with fresh enthusiasm having had a few days break from the modelling routine, but another part is frustrated that it's another year gone by and the project is still a long way from completion! Given that next year will be the 935-78's 40th birthday, I guess that's a good target to aim for.

The recent Photobucket situation hasn't helped my mood, either. My current plan runs through to September, but I will not be paying the $400 to enable the 3rd party hosting. I suspect the same is true for 99% of those on this forum using PB, and it's a crying shame that so much stands to be lost. I don't plan to close my PB account, in the (slim) hope that common-sense will prevail, but I'm not going to upload all the photos somewhere else and re-link to the threads, either! I see from the small-print that we'll still get the 3rd party hosting facility until the end of 2018, but will PB be around that long after this...? Ah well, it was fun while it lasted.

So, while I can still get photos on here, here's tonight's update.

Since Le Mans I've been working on the rear body, trying to decide how to mount the various parts and to convince myself that it will all go together:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1108_zpstasmryd1.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1108_zpstasmryd1.jpg.html)

The fit of the engine cover to the back of the roof section needs a little adjustment, the outer wings / fenders want to sit at a slight angle, and the inner bumper section isn't fitting quite right. So, not much to do then!

Until now the rear bumper has been left as a single piece, but I have had to split it into three sections in order to progress. Here's the right-hand section test-fitted into the wing / fender:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1109_zpsudztdkiy.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1109_zpsudztdkiy.jpg.html)

There's been plenty of filing, marking, test-fitting, more filing, etc, going on these last few weeks! It's been a very slow process, and the parts are still not finally glued together, but I'm optimistic that it will all work as planned.

To tidy the inside of the rear wings before painting I added an inner skin from 0.5mm plasticard. As well as covering and reinforcing the joint between the upper and lower halves of the fibreglass mouldings, it also gives me a defined step to locate the bumper section against. There's also a C-shaped styrene plate on the back of each wing panel, too:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1110_zpsxoonfsiu.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1110_zpsxoonfsiu.jpg.html)

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1111_zpsczqnsnjl.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1111_zpsczqnsnjl.jpg.html)

A length of styrene angle has been glued along the bottom edge to continue the flange detail, and to provide another locating point for the bumper panel. As the position of the bumper panels has slowly been refined, I've tidied up the shaping of the underside of the wings - but the final cuts will only be made once the inner panels have been glued in place.

I've been spraying these panels as I've progressed, as I decided it would be a pain to spray them once assembled. This also meant I had to sort out the rear lights too, as they would also be awkward to get at. I don't know where the inspiration came from, but I had the idea of overlaying a painted lens over a fine mesh to create the appropriate look:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1112_zps9h6hduqo.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1112_zps9h6hduqo.jpg.html)

This was a test piece put together to prove the concept - it had to look right, but I also had to be sure I could actually glue the parts together (without affecting the materials). I ended up using two sections of curved fibreglass cut from the mk1 bumper panel as base-plates, then a strip of mesh, 0.75 x 0.75mm styrene strip around the edge, then the plastic lens over the top (painted with Tamiya X-26 Clear Orange and X-27 Clear Red).

The overall effect changes depending on the light, but the mesh gives it that reflective sparkle and depth - the painted clear plastic on it's own would have looked flat and lifeless. I've also added three small screw details which will also be used to pin each light cluster in place:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1113_zpspwmimsck.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1113_zpspwmimsck.jpg.html)

As usual, you won't see much of these once the car is assembled, but they're there! The single round light on the bumper was much simpler - a piece of clear rod shaped on the lathe, painted with Clear Red, and pinned in place with a white styrene collar to hide the join.

The latest job is to start cutting and fitting the inner ducts for the two side-mounted radiators, ahead of the rear wheels. I made the fibreglass mouldings for these some time ago, but it's only now that I'm getting around to working with them! It's going to be a fiddly job - everything's at an angle, there's curved panels meeting other curved panels, and you can't get at anything with the rear wing in place. It's slowly coming together, though:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1114_zps2uojjkd3.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1114_zps2uojjkd3.jpg.html)

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1115_zpsf66ivrdr.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1115_zpsf66ivrdr.jpg.html)

I might end up laying a couple of small pieces of wet fibreglass in here to smooth things over, particularly towards the top where the curve of the inlet panel edge meets the main duct. I need to test fit everything with the rear wheels in positon sometime soon, too, just in case they foul the back of the ducts...which would be very annoying.

So, plenty going on. There's a few other bits and pieces I've done but not mentioned in detail - some brackets for attaching the centre bumper section, the backs of the rear lights, etc - but you'll probably see these next time.

More soon!

Cheers, guys.

I used CA to glue the mesh to the fibreglass backing plate, then UHU Expanded Polystyrene glue for the clear lens. I did a couple of test pieces to make sure, with no problems. I didn't put any glue below the clear section, though, just in case. The effect of the tail lights is a bit lost once they're buried under the bodywork, but I felt it was worth the effort.

Still not sure how I'll do the main headlights, but that's a problem for another time...

Hello again,

After sorting out the tail light lenses, the final headache with the rear wing panels was getting them to fit properly. This is still on-going, but the end is very much in sight. Here's an inside view of the wings:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1116_zpscgdjxtlb.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1116_zpscgdjxtlb.jpg.html)

The backs of the tail lights are simple styrene and box-section constructions, and will have some wiring added later. Just behind each wheelarch I've fitted a couple of mounting plates with tubular stays - these are designed to sit somewhere close to the outrigger frames which are part of the chassis:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1117_zpsmo7ynogx.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1117_zpsmo7ynogx.jpg.html)

The chances of getting these two pairs of frames to line up exactly were pretty slim, but my plan was instead to use them to stabilise the wing panels rather than being the main mounting point. There is still room to adjust the positioning of everything, so these frames will be finished later.

Next up, I added a couple of 0.75mm styrene plates to the inside edge of the two wing panels. This would allow me to improve the panel fit between the engine cover and the two wings, and it would also produce a nice crisp edge. Greenstuff and some filing and fettling brought everything into shape:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1119_zpsa3dsjrja.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1119_zpsa3dsjrja.jpg.html)

Finally for tonight, with all the adjustment and tweaking of the rear bodywork I found that the curve of the engine cover didn't quite match the curve of the rear wings. Not by much, but enough that it would create a noticeable step between the two panels. So, I had two choices: cut the panel and lift the outer edges slightly to improve the angle, or, to build up the top surface with styrene sheet and filler. I went for Plan A, and cut the panel:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1120_zpskgkyjrix.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1120_zpskgkyjrix.jpg.html)

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1121_zpscyayi2p5.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1121_zpscyayi2p5.jpg.html)

I ran lots of CA glue into the cut as a filler, then added the two thin strips on the back as reinforcement. Since taking the photo I've applied a little Plasto filler to the joint which will need sanding back.

So, another week and I should have all the rear bodywork fitting properly. I still need to add a bunch of louvres to each rear wing, but that's a job I'm leaving aside for a while - the Martini stripes will pass over the louvres, so it's going to be a really fiddly job to either cut the slots first then mask and paint, or to paint first and cut afterwards. Either way, I'm not looking forward to it! I'll have the same challenge at the front, too.

More next time,

SB

That means a lot, my friend...thanks.

So, what's new? Last week was a holiday week for me, so it was a good opportunity to do something 'different' with the 935. I decided to spend some time getting the doors sorted out - this would mean designing some hinges, painting the inner sills, fitting the door support pillars and - just maybe - making a start on the side window-frames.

I knew from the 908 that getting the doors to hinge correctly was not going to be easy. The two positives with the 935 were that the doors were opening conventionally sideways, and that the support for the hinges would (eventually) be solidly fixed in place. One major drawback with the Moby Dick is that the front bodywork is much wider than a regular 911, and the doors have an extra outer panel added to continue the aero down the sides - so the door is effectively twice as thick as normal. I did a bit of head-scratching to work out roughly where the pivot should be, and made a mark-1 hinge set-up:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1122_zpsy9kfk2uh.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1122_zpsy9kfk2uh.jpg.html)

It's a bit crude, but at this stage I just wanted to get a feel for how things would be. The genuine hinges on the real car are a curvier design, but there was no way I could replicate these with enough strength to support the door. I suspect even my version will struggle under the weight eventually, but it's not going to de-rail the project.

The mark-2 version was more refined, and the focus here was on trying to get more strength into the parts - I used a mix of angle and cut-down box-section to create a more robust connection to the door:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1123_zpszeogubhk.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1123_zpszeogubhk.jpg.html)

With the nose bodywork in place you can see that the pivot point is pushed right out to the edge - this should allow the doors to arc open without the aero panels fouling the nose.

By this point I was happy that the hinges could be made to work, so the next step was to fix the supports in place at the front edge of the door-frame. However, before I could do this I had to spray the sill panels - much easier to do this now, than later. So, I masked everything up:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1124_zpsj4u5s2xm.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1124_zpsj4u5s2xm.jpg.html)

...and after several coats of primer, then three air-brushed coats of Tamiya white:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1125_zpspmmjslei.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1125_zpspmmjslei.jpg.html)

No overspray into the cockpit, so that's good. A little touching-up required around the front on the floor, but that's not a problem. I could now make the mark-3 hinges and fit the support pillars:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1126_zpsxi1a0fwy.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1126_zpsxi1a0fwy.jpg.html)

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1127_zpskffiywu7.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1127_zpskffiywu7.jpg.html)

Each support pillar is pinned into the lower sill structure, and is glued to an internal bracket on the fibreglass wing panel. More CA glue was run into the joint, then packed out with Greenstuff. The mark-3 hinges have been drilled and temporarily pinned in place. There's still more to do on all these parts, but it's progressing nicely - I knew it would take time to find the right solution.

The final job was to have a look at the window-frames on the door. I wasn't entirely sure how to approach these, but have started with sections of 1/8" box threaded onto a wire core:

None of the pieces of 1/8" box are glued together yet, but there's potential for smoothing it all out, adding a thin outer skin if necessary, and generally just playing around with it until I get a good shape. The attachment to the inner door panel is temporary, and is one area which needs more attention - it needs a bit of juggling as the window-frames are currently attaching to the inside vertical face, where they should be attached more at the top. I'm blaming the lack of original drawings for this! I think it can all be made to work, though.

That's it for tonight. Next time I hope to have a couple of trimmed door panels, some door handles, and maybe some sliding windows to show...

Hello again,

So, here's the problem with the first version of the window frames - the 1/8" box section had to attach to the inner face of the door in order to line up with the pillars and curve of the roof:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1129_zpskkrhvxf2.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1129_zpskkrhvxf2.jpg.html)

At this point I had two practical options. I could extend the door panel on the inside face by about 1/8" and attach the frame to the top of this section, or I could push the existing panel 1/8" further into the cockpit and space the outer door skin back to the correct position. Extending the door panel on the inside was not going to be fun - it would have required more pattern-making and fibreglass work, and I'd already spent a lot of time making the existing parts. Option B was the preferred choice - putting an 1/8" packer under the door skin offered a better chance of a good result!

Given that the inner door panels were not now going to be altered, I could start adding some of the details required before painting. The 935-78 uses simple pull-cables to operate the door mechanism from the inside, and these disappear into two cut-outs at the back of each panel. I carved out the foam, lined the walls with styrene and made the two T-handles:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1130_zpswowz8ytc.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1130_zpswowz8ytc.jpg.html)

Next, the door strike-plates were made from three layers of styrene sheet, lots of filing, and some 'Wave' rivet heads:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1131_zpsjaq9fcby.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1131_zpsjaq9fcby.jpg.html)

Pinned in place for now, but will be painted and glued in time.

Before I could go much further with the doors I knew some painting was required. The recess in each panel would be difficult to spray once assembled, so I made some 'door card' panels from styrene and sprayed this section first:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1132_zpsk7awtqww.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1132_zpsk7awtqww.jpg.html)

The lengths of 1/8" box section are pinned at the bottom, and the upper pin which will support the window frame goes right through into the top. The doorcards are not shown, but have since been glued in place. Rather than gluing the spacers for the outer door skin to the foam core, I re-used the two mark-one door panels as an inner skin.

The next problem was realising that the door hinges were just not going to be strong enough. The ever-increasing weight of the doors was causing them to want to twist when opened, and I couldn't see a suitable solution. At this size and thickness I felt that re-making the hinges in fibreglass or thin aluminium sheet would not provide the required stiffness, and would cause other problems down the line - getting good glued joints with the ali, for example.

I've (hopefully) solved the problem by adding a second section to the hinge which will be pinned and glued to the front face of the door support:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1133_zpssbifxtrf.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1133_zpssbifxtrf.jpg.html)

I know it's not 'original' to the 935, but I'm not sure there was much else I could have done. They'll look better once fitted and painted, and if they allow the doors to be opened properly I'll be happy. When the doors are closed the weight isn't a problem, and it'll spend most of it's life on the shelf with everything shut!

So, here's the right-hand door before I start fitting the outer skin:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1134_zpstvc2s3yg.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1134_zpstvc2s3yg.jpg.html)

I had to re-make the door-side sections of the hinges as these were now mounting onto the sides rather than the front face; no problem - easy enough to do. The inner skin has been fitted and you can see the back of the cardboard used to pack out the styrene doorcards. The round hole will make it easier to fix the door pull-cables in place, before the outer skin is applied - as long as I remember!

You can see where I've pushed the door further into the cockpit by looking at the back edge of the opening. The window frame now pins into the top edge of the door, so that's good. The three lengths of box section are the early stages of adding the spacer for the outer skin - the tricky bit here will be filling the gap around the edge, but I've got plans for that...

Finally for tonight, a small detail but one that's worked out quite nicely:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1135_zpszhk3jj6b.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1135_zpszhk3jj6b.jpg.html)

Time to add some door handles! I cut the hole in the outer skin, glued the small fibreglass recess piece in place, and the handle is pinned over the top. The main part of the handle was cut and filed from a piece of 4.8 x 2mm styrene strip, 0.5mm 'seals' added at each end, and the release latch fitted to the back. I'm very pleased with the result - even if this photo does suggest that the fibreglass door skin has the texture of golf-ball...

Here's the whole lot all together - still work to do, but you can see what I'm aiming for:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1136_zps76vfkoxf.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1136_zps76vfkoxf.jpg.html)

The only problem now is that I have to do a lot of this work again for the other side! Oh well, it'll keep me busy...

As ever, have a good week.

Hello again,

Slightly scary that it's been a month since I last posted an update - as before, it's not for a lack of progress. Instead, it's more that a lot of what I've been doing isn't particularly...exciting...so it's taken a while to get a half-decent update together!

Something I touched on last time was the need to expand the outer surface of the inner door structure - here's the rear edge built-up using a notched length of styrene angle, greenstuff, filler, etc:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1137_zpsjegm4r8d.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1137_zpsjegm4r8d.jpg.html)

At the front, I've pinned the hinges in place and added various pieces of styrene strip as both reinforcement and to seal the gap between the inner door and the outer fibreglass skin:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1138_zpskie5exmn.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1138_zpskie5exmn.jpg.html)

It's not immediately obvious, but the window frames have been glued together and had a thin 0.25mm outer layer of styrene sheet added. I'm not going to do any more work on these until the roof section and the door hinges are glued in place - too much potential for things to move!

So... I reached the stage where I had to get the roof section ready to fit. The weather is only going to get colder and wetter from now on, so I wanted to get the roof painted before the winter - it's going to stop me doing lots of jobs if I can't get it painted until the Spring. My plan was to spray the inside with grey primer (ahead of a black final coat), and to spray the outside with white primer for a white final coat.

I spent several evenings working on the top section adding little bits of filler, cleaning bits up, and basically getting things ready for the weekend. Given that most of the interior will be obscured once assembled (and be in natural shadow too), this didn't need quite so much attention as the outside:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1139_zpsiva9tape.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1139_zpsiva9tape.jpg.html)

The outside required more filler-work, and I was quite expecting that it would still need more after the initial coat of primer. It was more about seeing just how bad things would be!

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1140_zpsrkhonog4.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1140_zpsrkhonog4.jpg.html)

In this photo it doesn't look too bad, but there are several areas that need attention. After spraying the black interior there's a few places where removing the masking tape has also taken the primer, but that's not a major problem. Here's the shell masked-up and with three coats of Tamiya semi-gloss black:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1141_zpsklruyucj.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1141_zpsklruyucj.jpg.html)

While spraying the shell, I also painted the turbo air inlet ducting and the four inner hinges:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1142_zpsubp70xbm.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1142_zpsubp70xbm.jpg.html)

It's surprising how much difference a coat of white primer makes:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1143_zpshjmootv2.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1143_zpshjmootv2.jpg.html)

Other than the outer 'running-board' sections, everything currently fitted to the chassis is now painted (to varying degrees!). You can see the areas where the masking has removed some of the primer, but I suspect most of the roof will be papered back to bare fibreglass again during the coming days. In preparation for fitting the door hinges I touched in the greenstuff weld details on the doorframe supports.

So, what's next? I'll spend the next few evenings working on the roof again, with the plan to re-prime it and maybe get some Tamiya white sprayed on at the weekend. While I'm at it I guess I could also prep and paint the running-boards too. I'm also going through all the small little bits and pieces that need hand-painting before fitment - the windscreen motor mechanism, starter motor, etc, making progress on several fronts. I need to tackle the dashboard top and instrument pod cowl soon, too, as they will need to be installed before the roof is fitted. There's not much more that actually needs to be made (seatbelts, steering wheel, headlights, tyres and wheel covers, etc), but I'm now trying to work out the final assembly sequence...

At some point during the next few weeks I might put together a huge parts list for the project, to hopefully make it easier to see what's still to be completed. I might get a few surprises!

Have a good week - more next time.

Hello again,

I'm trying to get on top of various jobs before I have some time-off from work later this month. I've got all sorts of things planned for that, but first I need to do some preparation!

Firstly tonight, here's a few small bits that have been painted recently -

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1145_zpsaoyh47l4.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1145_zpsaoyh47l4.jpg.html)

Rear anti-roll bar with mounting blocks, door mechanism pull handles, door strike-plates, external door handles, wiper mechanism, and two ignition spark-boxes (I think!). The wiper mechanism was a major pain to finish - the little linkages were so fragile that I broke them twice during the painting process. First time I re-made the link, the second time I just glued it all together - it'll barely be visible once assembled.

You might remember that I started making the first spark-box months ago...but never got around to completing it. For a long time I was only going to fit the single unit (as I didn't think the second was technically necessary) but there were enough period photos showing the pair that I gave up and made another. As is often the case, the second only took a couple of evenings, after the months required for the original...

Next up - the dashboard top. As I'm hoping to fit the roof during the winter, I need to complete as much of the interior first. The instrument pod cover was filed to suit and glued in place, with a length of split wire sheath added as a length of edging strip. On the left-hand side I added a length of half-round styrene for the edging, and filled the cutout in the middle with a piece of scrap fibreglass:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1146_zpssiml9myf.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1146_zpssiml9myf.jpg.html)

My original plan had been to cover the top panel with cloth (as per the seat), but I was so pleased with the results of the textured paste on the intercoolers that I used the same technique here:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1148_zpstvzmq3ef.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1148_zpstvzmq3ef.jpg.html)

Amongst all this I've been painting and re-painting the roof section and the two running-boards. The roof still needs a little work, but the running-boards are basically done:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1149_zpsiblzefgm.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1149_zpsiblzefgm.jpg.html)

Trying to get a smooth finish on these fibreglass parts is killing me! No matter how smooth it feels, once that first coat of primer goes on all the tiniest of pin-holes and imperfections show up! So, for the next batch of parts I'm getting in with the filler putty first:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1151_zpsx1l4q68z.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1151_zpsx1l4q68z.jpg.html)

I've also been puttying the rear wing end-plates (both inner and outer faces), the wing main plane (again...) and the rear bumper centre panel. They'll all get a coat of primer next weekend, and hopefully they won't need too much rectification before the top coats. Given that I've still got the large front body section, bonnet, doors and the two rear wings / fenders to door, three more tubes of 'Mr White Putty' and another can of white primer are on order...

Finally for tonight, I spent a large part of last weekend making these:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1150_zps1sx0gxer.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1150_zps1sx0gxer.jpg.html)

Not spinning-top toys, but patterns for making two headlight bowls and two fuel filler-neck collars. The headlights are one of the jobs I want to tackle in a couple of weeks - I want to make the bowls in fibreglass, line them with aluminium foil, add some sort of electrical and bulb detailing, then make two lenses. The filler-neck collars will be trimmed back to match the underside of the bonnet panel, and will probably receive a rim of split wire sheathing. I'll make a start on laying up the fibreglass next week, so they're ready to work with later in the month.

The list of outstanding jobs doesn't seem to be getting much shorter, though...!

More next time,

Just when I think you've been slagging off... But no... ;)

It's all looking fabulous as usual. One thing that gives me a slight pause is the texture of the dash top though. The 4th pic down in this installment seems a bit rough-looking? I'm trying to reconcile it with the dashes in my 80 targa and 87 coupe, but not really able to...

Love the first 'handful o' goodies' shot though!

I continue to watch this incredibly inspiring work with regularity.
But I second ianc's opinion: it seems the dashboard is too textured.
Maybe the cloth solution is a better one.

Just my 2 cents.

Okay folks - don't let it be said that I don't respond to constructive criticism! Take one dashboard top, add double-sided tape, CA glue, and what's left of one of my old work shirts:

Hello again,

I always find the best thing about modelling while on holiday from work is that I can tackle certain jobs that would be a major pain to do during a normal week, a couple of hours each night. With this in mind, I made sure that everything was in place and prepared so that I could dive straight in last weekend.

First up, here's the headlight bowls and filler neck collars being laid-up with fibreglass:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1155_zpspvgke0rn.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1155_zpspvgke0rn.jpg.html)

No problems with the resin / hardener mix this time, everything went off as planned and I only needed to use four layers of the thinnest cloth. They didn't even fight me when I tried to remove the parts from the moulds:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1156_zpsg1xyrygc.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1156_zpsg1xyrygc.jpg.html)

I'll return to the headlight bowls another time, but the filler neck collars were easy to trim to size:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1157_zpstbcqrlu8.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1157_zpstbcqrlu8.jpg.html)

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1158_zps6pyxfums.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1158_zps6pyxfums.jpg.html)

I just need to add a couple of small overflow lines to these and they're ready for painting.

Staying in the front under-bonnet area, I've trimmed the Mk2 bonnet panel (made some time ago) and added the holes for the oil and fuel fillers:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1165_zpsw3err3sk.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1165_zpsw3err3sk.jpg.html)

In each corner of the bonnet I've added a small 2mm diameter magnet, with matching magnets hidden under the edging of the nose section. It's not a super-strong attraction, but it's enough that it does a good job of locating the panel in place. There's some styrene strip and panelling added around the edge of the bonnet opening, so it's all looking tidier. The bonnet itself now needs some major rubbing-down before it's ready for filler and painting.

In the front two corners you can just about see that I've also added a pair of locating pins. These go through the bonnet and are glued into the chassis X-frame. Eventually there'll be a couple more at the top corners too. To go with these, there should also be some removable bonnet clips, right? Something like these:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/Scratchbuilt%20Porsche%20Moby%20Dick/moby1163_zpsdpmukhw0.jpg (http://s604.photobucket.com/user/ScratchBuilt917/media/Scratchbuilt%20Porsche%20Moby%20Dick/moby1163_zpsdpmukhw0.jpg.html)

These will be tethered to the bonnet panel and left to hang free - I am not even considering making them functional!

Next up, the steering wheel. A different technique for this one - normally I curve a piece of plastic hose over a wire core, but this never results in a nice round wheel. So, this time I cut five rings from 0.75mm styrene sheet, glued two pairs together to make the front and back for the rim, and cut notches in the fifth to locate the centre spokes:

This lot was glued together and left under a heavy weight for a few days - I will be very annoyed if it starts to warp out of shape! The next step was to start shaping the rim, so I fitted it to my small modelling lathe and gently attacked it with emery cloth:

The three-spoke centre was also marked and trimmed from 0.75mm sheet, making sure that the spokes lined-up with the notches in the rim:

The upper part of the steering column was made from various pieces of aluminium tube and styrene. Small hex-nut detailing was added to the back, and some 'capscrew heads' added to the front (two of which allow me to pin the centre to the column. Greenstuff was added around the outside and inside of the rim to smooth everything off, and some small holes added for stitching detail. It's now pretty much ready for painting:

Finally for tonight, I've made a start on the components for the seatbelts. I want to make these even more detailed than the ones on the 908-03, but they're always a fiddly job. I still have to make the release buckle for the lap-straps, but all the other plates and mountings are well underway:

I'll continue to work on these during the next few days, and hopefully by next weekend they'll be ready to fit into the car. Time for some needle-work!

In amongst all this I've been doing a little priming and painting too, but this can wait until the next update when things are finished. There's a few other jobs I'd pencilled-in for my holiday - headlights, re-making the tyres, making some more decals, etc - but I don't think it's all going to fit in! Still, it won't be too long until Christmas...

That's it for tonight. Not heavy on the technical detail, but I think by now you know how I do what I do! Hopefully next weekends update will have the same variety - and some finished parts.

Great update
I love particularly the "stitches" on the steering wheel; a great detail!

I too love the wheel, with the attendant stitching holes. How do you plan to simulate the actual stitching there though? Tricky...
