Hello Again!

One week later than planned, but here's the WIP for my current project - a 1/8 scratch-built Porsche 908/03. This car was originally raced in 1970 and 1971 as an alternative to the 917 on the Targa Florio and Nurburgring 1000km, where lighter weight and improved manoeuvrability counted for more than outright power and speed. For now, my plan is to make one of the original 1970 cars - probably painted in Gulf colours - but there's plenty of time to make changes.

Work started in late November 2008, so if my previous Porsches are anything to go by, this should be in the 'Completed Project' gallery sometime in late 2010...

Here's the basic chassis frame (3/32", 1/8" and 5/32" plastic tubing):

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083010.jpg

I use a large 14" x 10" bathroom tile as a base-plate for my chassis-work; the lower frame tubes are drawn accurately on thin card, and this is taped to the tile. I then use a selection of Lego bricks and plates held down with double-sided tape to position the plastic tubes and ensure everything stays square and true whilst I'm gluing. As the chassis grows I can add more Lego to support and align the new tubes; once the key points are fixed, the diagonals can be added 'free-hand'.

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083008.jpg

So far there's enough of the chassis completed to allow me to make progress with the rest of the model. There's still a section to add which will support the rear bodywork, but this will only get in the way if I fit it now. Similarly, there are a few more tubes needed above the footwell and the around the front wheel-area, plus the main roll-over hoop; these will wait until I have some bodywork to fit.

Pedal assembly:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083016.jpg

The master cylinders need to be finished and a few plastic hex-nuts added for detail (thanks for the hex-section, Hiroboy!), but they're well underway. I tend to leave painting the sub-assemblies until much later in the project, just in case I need to make modifications.

Next up, the engine:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083012.jpg

Having worked out the basic measurements on paper, I made the core structure from various square and rectangular-sections. This replicates the main block / cylinder barrels section of the actual engine; the cam-boxes can then be added each side, the inlet and fan detail to the top, sump detail to the bottom, etc. The 8-cylinder engine in the 908 has much in common with the larger flat-12 in the 917, but it's different enough to make it a fresh modelling challenge.

Here the cam-boxes have been added, plus the early stages of the timing-chain drives at the front of the engine:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083004.jpg

Here you can see the engine core dropped into the chassis frame - it's going to be snug once it's all built-up, but everything should fit okay.

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083007.jpg

I'm currently continuing with the engine, building-up the block and sump detailing so that sometime soon I can start on the inlet trumpets and fan shroud. The exhaust system can wait until later in the project - it's probably easier than bending real exhaust pipes, but it's always a job that I leave until I'm in the right mood! I keep reminding myself that at least I'm only having to make eight pipes, eight inlet trupets, etc, rather the the twelve sets on the 917's...

I hope this is of interest for now. I'll try to keep the updates semi-regular, but it's going to be a long haul. Any questions - please ask!

Thanks for looking.

Once again, thanks for the positive response, guys.

It's early days on this one, but I'll keep adding to the thread throughout. Now everyone's seen what I'm doing, I can't stop - can I?!

So far the only chassis plans I've found for the 908/03 are in a very small picture in 'Excellence Was Expected', so all I have is a side elevation and plan view. In the same book there's some good sections through the 908's engine, so this has given me something to work with - the tricky bit is working out the scaling factor for each drawing to translate it into 1/8. I also have one of the 1971-type cars in 1/18 scale by AutoArt, so this acts as a useful 3-D reference.

In some ways it's a shame the 917 overshadows so many of Porsche's other sports-racers - does anyone know of a book solely devoted to the 936, for example? (please tell me, if you do!) Still, there's just enough about the 908/03 in most of the other books that I reckon this project can go all the way to a finish. Then I can start on the 936...or the 956...or the 935/78...or...

Hello again...

Work continues on the engine - mainly adding more detail around the front cam-drive boxes, the front mounting / fan drive section, and at the rear. As usual, it's all styrene strip, tube and box-section...

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083020.jpg

I'm having to cross-reference a whole pile of photos to put the detailing together. There's quite an offset between the two rows of pistons, so the gap between the two sets of drive-boxes needs filling with all sorts of lugs, bosses, unions and webs. Once it's installed in the chassis you'll hardly see any of it...

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083019.jpg

On the type 912 engine in the 917 the oil feeds in and out through the front housing; on the 908 engine (from what I've been able to work out), it looks like the main inlets and filter unit are at the back. The spigot coming out the back of the block will match-up with the gearbox and provide a solid joint between the two - the only mounting that is actually on the engine is at the front, the other two hang off the sides of the gearbox.

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083017.jpg

I've made a start on the main cooling fan, the alternator drive pulley, and the top plate which will form the basis for the fan shroud. Hopefully you'll see more of this next week.

Cheers!

Here's what I've been up to this week...

Firstly, various engine parts. Back row: oil filter housing, cooling fan assembly, front cover core. Front row: alternator drive pulley, cooling fan drive pulley.

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083021.jpg

The cooling fan needs a little tidying-up, and the front cover core needs building up with greenstuff, plus more detailing. The two pulleys are pretty much ready to be painted (but that's a long way off...)

Rather than create the front section of the fan shroud from styrene sheet, I found that an old 35mm photo film container worked perfectly! Trimmed to length, with a backing disc fitted to give me something to glue the fan to, it was just right. The cooling fan assembly pushes into place as shown:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083023.jpg

I've also made a start on the main fan shroud which covers the top of the engine. This will be bulked-out with box-section and then finished off with greenstuff and plenty of fettling with fine emery cloth and wet & dry paper:

Hi!

Very, very, very impressive!

I particularly love the engine details! Everything made out of styren sheets!!!!

One question, as the parts are mostly foundry parts, will you try to give this particular "angled" (don't know how to say in english, this is an angle given to straight walls in order to unmold parts, instead of perpendiculars shapes) shape to all those components?

If yes, hav you got any idea about how to proceed???

THanks for sharing!

Hello again.

Sorry about the lack of photos in this post - I'll hopefully have something ready to show in a day or two. I've been concentrating on the distributor and fuel injection unit this week, plus I've made a little progress with tidying up the cooling fan and housing. I think I'm avoiding the main part of the ducting shroud for a while - it's one of those awkward jobs that's only going to look good at the last moment.

Regarding getting the draft angle on the cast items, it's probably a detail too far for me! It might not show too well on some of the photos, but on larger items such as the cam covers I've added strip and quarter-round sections to the sides to try and get away from a regular 'box' shape. Most of the square-section plastic has rounded corners anyway - and some have slightly convex faces too - so you can still have the suggestion of 'cast' shapes rather than the look of something 'milled from solid'. On the smaller items the angle would be so fine anyway, I don't think you'd notice. On things like the gearbox and calipers, the core shape is neatly camouflaged by all the webs and fins, and I suppose the painting helps too - you can draw attention to certain elements, and hide others...

Cheers!

Okay, here's a couple of photos to go with the previous post. First, the distributor and fuel injection unit:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083035.jpg

Both parts need a little more fine-detailing. On the distributor I plan to turn the plug-lead ends on my Unimat, rather than using just plain lengths of styrene tube. The fuel injection unit needs a small bracket to mount a support stay, plus the mechanism to attach to the throttle lever. A little greenstuff to fill in the gaps, and it's about ready.

I've also fitted the engine mounting casting to the front of the main block, and filled the sides with greenstuff. The fan shroud has been covered with 0.4mm sheet, and the gaps at the front filled too.

Hello again!

It's been an odd couple of weeks - it doesn't feel as through I've made much progress, but the bits are there to suggest otherwise. I guess it's because it's all been small fiddly stuff...

First, I've been getting on with the inlet manifold / throttle slides:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083038.jpg

They're two lengths of 3/16" square section with a 0.75mm stip sandwiched in-between, 2mm half-round down the sides for the bolt flanges, then more strip for detailing. The main inlet trumpets will hopefully be slightly tapered, rather than just using straight tube.

I also had a major nut-fitting session on the cam covers...

The major development last weekend was the first use of my Unimat lathe. First job - turn down 5mm lengths of 3/32" tube to make the sparkplug lead boots:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083039.jpg

These are all drilled and pinned into the top of the dizzy; I'll fit the remaining eight plugs later. Unless I want to be lazy I'm also going to have to make 16 more for the pluglead boots onto the head, but that can wait for the next lathe session.

Second job for the lathe was to make components for the fuel injection pump pulley assembly:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083040.jpg

The main injection pump pullley is all aluminium, in two parts. The smaller pulley for the end of the camshaft has an ali core, with plastic detailing for the end. The teeth are made from 0.25mm x 0.5mm strips, carefully glued in place - luckily, the spacing came out perfectly. That was a happy hour or so on a Saturday night...

Cheers!

Hello!

I finally made a start on creating the main fan shroud this weekend:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083043.jpg

I'll bulk-out the gaps with offcuts of box-section, etc, before adding large amounts of greenstuff putty to create the final shape. So far, it's working out okay...

I've also been adding a little more detail to the fuel pump and inlet manfolds / throttle slide housings:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083041.jpg

The overhanging mounts for the throttle lever assembly were tricky - getting the angles and positioning just right was not a five-minute job! The bracket on the side of the fuel pump will be used to mount a support bar running to the oil filter housing (not shown). I couldn't resist gluing the drive-pulley in place, either. I've also made a start on the ends of throttle slides themsleves, but they're so small I don't think they'll photograph too well until everything is assembled.

That's all for now!

Hello Scratchbuilt,

Congratulations on the progress that you are making on your 908/3. I have been working on a 1/12 version of the 1971 Nürburgring 1000Km, Elford / Larrousse car on and off for nearly ten years so your efforts will, I hope, encourage me to get a move on with my part scratchbuilt part Tamiya based model that can be seen here:
http://www.f1m.com/main/forum/viewtopic.php?f=29&t=9530&start=0 (http://www.f1m.com/main/forum/viewtopic.php?f=29&t=9530&start=0)
On pages 1 and 2.

While not wanting to be negative on my first post I feel that I should question one part of your model. I refer to the positioning of the vertical cooling fan at the front of the engine, when constructing my similar model I initially put the fan on the centerline of the engine only to discover later that the drawings that I was working to from the VSRN web site here:
http://www.vsrnonline.com/Mags/MC/Vol8/V8N9/MC_V8N9_p409.jpg (http://www.vsrnonline.com/Mags/MC/Vol8/V8N9/MC_V8N9_p409.jpg)
were not wholly correct.

Looking at the images from these links:
Google Image Result for http://www.scheuern.com/mbhist98/images/908close.jpg (http://images.google.com.hk/imgres?imgurl=http://www.scheuern.com/mbhist98/images/908close.jpg&imgrefurl=http://www.scheuern.com/mbhist98/908close.htm&usg=__lN-gk4wKAf27oEvkPBD71xJXYlk=&h=432&w=540&sz=39&hl=en&start=9&um=1&tbnid=2h7NKtsN4k4vdM:&tbnh=106&tbnw=132&prev=/images%3Fq%3Dporsche%2B908/3%2Bengine%26hl%3Den%26sa%3DN%26um%3D1)

http://www.pelicanparts.com/vasekauction/908/med/DSC02079.JPG (http://www.pelicanparts.com/vasekauction/908/med/DSC02079.JPG)

It would appear that the fan is offset to the passenger side of the car by a small but critical amount, I missed this originally and only detected it when I started to make the top air duct / shroud between the two rows of injection trumpets and couldn’t get a good fit around the fuel injector pump, when I looked at the photographs again it was apparent that the shroud and therefore the fan is noticeably closer to the injection trumpets on the passenger side of the engine than the trumpets on the drivers side.

My only hope is that you have evidence to the contrary and that therefore I will not have to modify the centerline mounted fan that I have built on my model.

Another week, another update...

After bulking-out the fan shroud with box-section, I used large amounts of greenstuff modelling putty to fill the gaps; a first layer to create the overall shape, then a second thinner / smoother layer to give me something to work on with the wet'n'dry:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083050.jpg

There are a couple of areas which need some fine filling, and the transition to the plastic base-section needs more work, but you can see what I'm trying to achieve. It looks better when the photo's the right way round...and in focus...

I needed a change of scene after all this, so it was time to start on the exhaust system:

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083047.jpg

The pipes are 100mm lengths of 3.8mm clear hose (from the aquarium section of a pet-supplies store). I used a length of 1.2mm gardening wire up the inside to allow me to create the shape I wanted - stiff enough to not snap back into place, and flexible enough that I can adjust and modify the curves as necessary. The short ali sections gather all the primary pipes together, and will allow me to make the final tail-pipe sections as seperate pieces.

http://i604.photobucket.com/albums/tt121/ScratchBuilt917/9083048.jpg

The ends of the inner wires pass into the bottom of the engine, and the short sections of plastic tube will be detailed to create the mounting flanges for the pipes. The tailpipes will be made from more plastic tube and greenstuff to get the transition from four-to-two-to-one.

Ideally the exhaust pipes should be a slightly larger diameter - probably about 5 or 6mm - but this creates problems: the plastic hose won't hold the shape without a wire core, and if the wire gets any thicker it becomes much harder to work with. There's not much space to get all the bends in, so the smaller pipe size works well.

Finally, thanks for the message, Hack Saw. Yes, the main fan is slightly offset from the engine centre-line; on my model it's about 1.4mm towards the passenger-side. Not much, but enough...

Back in the real world, the racing season is just about getting started here in the UK, so next weekend I'll be off to Silverstone with the FF2000's. I'll do my best to keep the posts regular, but they might slip to mid-week.

Cheers!

Hello again!

Following the last post, the exhaust pipes have had a little extra tweaking - I'll leave the rest of the system until the gearbox is in progress (just in case something gets in the way). So, I've returned to detailing the main engine parts:

More thin plasticard has been wrapped around the fan shroud to create the angled front section, with two layers of 0.5mm square styrene to make the flange detail. The fit between the front and rear sections has been adjusted to remove a small gap.

I've also fitted the last eight plug-lead ends to the distributor; now it just needs the two main leads from the ignition coils. You can also see the shaping around the front of the fan shroud from this angle.

The alternator body is another short section of till-roll, with extra plasticard detailing and a machined aluminium pulley. The electrical connections on the rear need to be added, and the drivebelt will be fitted at a later date:

The plan for this weekend is to make a start on shaping the male buck for the fibreglass bodywork - I'll need to make some drawings first, then get busy making a mess with the blue insulating foam. It's a good opportunity to get two or three solid days progress, rather than just doing an hour or so every evening. Unlike the 917-10, the body shape of the 908-03 is somewhat curvier - particularly around the nose - so there could be one or two challenges ahead...

More later!

For some reason, my e-mail updates of new posts stopped for a while, so I've only just caught up with your updates, & I can't think of anything to say that hasn't been said already - this continues to be a simply magnificent piece of work! The small components like the distributor & fuel injection unit are just stunning - unbelievable to think you can create such detail from such simple materials! I do think it's cheating though, starting to use a lathe....!!! :iceslolan

One question, when you say that you use 'greenstuff' to bulk up the fan shroud between the formers, do you mean the MMD Squadron one part putty that comes in a tube? I use this a lot in plastic kit assembly, but find that if I use anything more than very thin layers it continues to dry for weeks or even months after the model is finished, leading to sinkage visible under the final paint. Do you not get that when using such big quantities of the filler? Or is it a different 'greenstuff'?

Keep on going, this will be an absolute masterpiece of a model!!

Amazing work!!! I saw 4 of these cars up at Road America together for the
BRIC a few years ago. One of them had a over restored fiberglass tub(all new and perfect). Amazing little cars. I like the Martini colors best myself.
You engine looks like real, other than the fact that its white plastic..

Hi Keef,

The 'greenstuff' I use is made by Games Workshop here in the UK - it's a two-part modelling putty (mix together the yellow and blue and you get green...) It goes off surprisingly quickly, even in large quantities - you don't get problems with the top surface going solid, only for it to be squishy below. I've used some Humbrol model filler in the past, and know exactly what you mean! It doesn't eat into the plastic, either, so for my purposes it's ideal.

And yes, I have a twinge of guilt whenever I use the lathe...

Cheers!

Utterly marvelous update, as ever Scratchbuilt! I was also assuming it was the nasty Squadron stuff too! May have to try some of the Games Workshop stuff out now. Do you ever use ordinary bondo/polyester filler? I've had some success with Dolphin Glaze. Goes on thinner than the usual car body filler so you can smooth it on nicely.

my lord, 1/8? these things are getting bigger and so much more detailed. Why didnt you just scratchbuild the 1:1?

Great work!

Thanks for the reply on the putty Scratchbuilt! I'll have to try some of that, never got on with Miliput for some reason! I thought it would have to be a different greenstuff - the squadron putty probably wouldn't dry before Christmas if you used that amount!!

Glad I decided to check your thread again, as for some reason my e-mail notifications have stopped again - really annoying!!
