Okay, I know everyone weighed in about continuing the F40 or starting a new build and I appreciate everyone's enthusiasm, but this project has been gnawing at me for years... This may be my all-time favorite car for many reasons and I may end up building a 1:1 version as well, but I had to at least start on this project... I first did a set of plans... on the back of blotter sheets, no less! I started the body mold last weekend by stealing a page from Scratchbuilt's technique of XEPS foam and fiberglass layup... The body mold is coming along nicely and should be ready for the first coat of filler soon... Today, I started the frame and got the basic ladder done in 1/2 inch brass tubing... this is going to be incredible and I hope everyone follows this build with the ferver that you did the F40 build... This one just might be better...

Garey....I will not mention the F40 anymore :) And I am going to follow this build with great admiration! Are you going to give the car a brass body or will it be polyester? Is it curbside or with a scratched/bought engine?

Thanks guys... Ton, you know me better than to ask if it will be curbside:lol: Of course it will be full detail, working suspension, steering, etc. Everything will have to be made, since there is nothing in 1/8th scale to support this build. I am planning on a fiberglass body, since I didn't want to spend the time to make a wooden buck to hammer a tin or copper body out on. That would be a project in itself! But I may do a 289 FIA version after this one and try a metal body on that. I still want to do a 1/8th GT40 and a McLaren MK8 and maybe a Grand Sport Vette down the road, so I hope this project goes as smoothly as I have planned it to... only time will tell!

Wheyhey! Nice one Garey - imagine that lined up with the RS60!:biggrin:

One of my favourite cars, so I'm really looking forward to this and I also wanna do a GT40 too!

I had a look at an apartment recently that is built on the grounds of the old AC factory which is near me! Not as glamerous as it sounds as they ended their days making 3 wheelers for invalids - disgraceful!

Good luck with the build mate

Thank you sir... I envy you guys that live across the pond and can experience all of the history of the classic age of motorsports just by walking out your front door! I'd love to travel to the UK for that reason!

Our 2 cars side by side would be a treat, indeed. I have this build posted on Club Cobra also and I am in communication with a guy from Istanbul who is getting me a lot of reference and even CAD designed chassis and body files from his 1:1 build he has been working on from scratch for 12 years! I hope that this build continues to be a treat, it definitely has been so far, but it's still early on. Maybe we'll have to put our heads together when the time comes for the GT40 build... I have been quietly collecting reference on that one for years now...

2 steps forward and 1 step back, as they say... I am not satisfied with the shape of the body at this point, so I have decided to take some more critical measurements and adjust my drawings, as necessary. This, of course, means that I will redo the foam body mold, as well. There are a few guys on the club cobra site who have given me some suggestions as to where the shape should be adjusted to make it more correct and less like some of the kit cars out there. Since I'm wanting to build this as an original Shelby 427, having the body shape wrong shoots this project in the foot, before I even get it going... I'll post some new pics in a few days...

Thank you sir, this one is just getting started, though... check out my F40 build on this site, it's much further along and just as crazy as this build...:)

http://www.automotiveforums.com/vbulletin/showthread.php?t=935735

The F40 is based loosely on the Pocher kit, so alot was there to start with. The Cobra is completely scratchbuilt, so everything has to be machined, cast or created from my drawings, which also had to be created. Truely a start from nothing build...

Quickie update before I turn in for the night... worked on the rear suspension/differential mounting "box" tonight. Got all of the tubes roughed in, so I'm making some progress... Should start to move a little quicker from here as the rest is peripheral tubing and gussets/plates... actually, there are alot of them, so it may go slower:shakehead:shakehead:shakehead

Thanks Ton,

I have this build posted on Club Cobra also and as it turns out, the Cobra owners are a sticky bunch when it comes to getting it "right". I have gotten a bunch of good feedback from several members about what looks good and what needs to be fixed. That is actually why I joined that forum and it seems to be moving in the right direction. I have gathered a fair amount of reference, but as we all know, getting input from someone who owns the "real deal" is invaluable. There may be a 2 steps backwards to go 1 step forward here for a bit, while I get it "right", but it will be worth it in the end. Stay tuned...:smile::smile::smile:

Hi bmwmech1,

Mmmm....looking good. A bit of a change from the F40, but you've got to enjoy what you're doing if you're doing it for a long time! 'Sculpture' is right - there's something great about seeing a bunch of tubes come together to make a chassis like this. As much as I love modern F1 cars, they don't really excite me as a potential modelling project - give me an old-fashioned spaceframe any day! I've got a book on the Cobra somewhere - I'll have to dig it out to follow what you're doing on this one. Didn't some of these have transverse leaf springs at the front, or was that on the 289's?

Cheers!

SB- funny thing when i just logged on... your 908, Cingsters RS60 and my 427SC were the first 3 threads at the top of the list... all 1/8, all in a row... who says the big ones don't have a following, right? Anyway, this one has become a bit of a torment, but I think I have my hands on the definitive reference now... Everything one could imagine and all dimensions to boot! So, I am starting over, since trying to patch up what I have is not really worth it. What I have to this point is close, but with the reference I now have, what's the sense of close, when it can be exactly right, right? I will say that trying to convert 2 dimensional drawings to 3 dimensional in foam for the body buck is very difficult. Hats off to you, mate! You make it look easy! I want to do the body in 'glass like you have on your builds, but I have 2 body bucks done already and neither is correct! The one has a "perky" rear and the other, the correct rear and a 289ish front... ugh! Maybe 3rd times a charm, no? About your suspension question... yes the 289's had the original AC transverse leafs at front and rear... the 427's used unequal length A-arms in front, a 3 bar setup in the rear and coilovers at all 4 corners. That is the version I'm building now. Depending on how this one goes, I may do a 289 version next... we'll see. Alright, gotta fly and start cutting up some more brass...lots to do!:cool::cool::cool:

Alright, now I'm cooking with gas... so to speak. After alot of work last nigh and tonight, I have some progress in the right direction! Actually, if the rest goes like this piece, it might take a while, but it will be dead nuts, spot on, no questions, perfect! I now have the rear chassis sub-assembly done and whoa... it was dicey to build, but it is 99.99% accurate, the last 100th of a percent going to accuracy in measuring in 64ths, which is pretty damn small.... my eyes hurt from looking so hard! Anyway, the piece came out super nice. I'm waiting for some more 1/2 brass tubing to come tomorrow, so I did this assembly, since it was pretty intricate... enjoy!!!

Just to give you a better perspective on size, the 3 lightening holes in the rear plate are a scale 2" in diameter, which is 1/4" in 1/8th scale. It's not tiny, but then again, this assembly is made up of 11 pieces of plate not including the bolts, nuts and washers... try to solder that all together without the first 3 pieces falling back apart...:screwy::screwy::screwy:

The chassis is looking fantastic! We had a guy turn up in a 6.3 V8 Dax at our college last weekend which looked fab. I must admit when I saw your drawings I thought the sides in plan should be curved and couldn't believe the hood sides were so straight. Low and behold after checking over the Dax your's appear to have it spot on! :)

Thanks Cing,
but as you well know, having a good set of prints and being able to translate 2D to 3D are 2 vastly different things. I have 2 body bucks and neither one is "right". Still need to make a third one and integrate all of the best parts of the 2 failed attempts. I'll get around to it... I'm ramped up about the chassis right now!

01-31-2010, 09:43 PM
Thanks for the kind remarks...I don't know about a watch... I do enjoy it, though and the more tedious the part is to make the more "zoned" I get, Lol! I didn't make as much progress today as I'd hoped, but progress is still progress. I have changed much of the construction, this second time as some of the assemblies must be re-heated several times to add all of the brackets, gussets and mounts. I have pinned almost everything to everything else, so I have an integral attachment between 2 pieces that have to be re-heated. This took alot more time, but has already paid off, so it was worth it in the end. If you look closely in the first photo, you can see the circles on the top crosstube left from the 1/32nd rod I used to pin everything. It may not seem like much, but having that little rod in the solder joint keeps everything from wanting to come apart when re-heating... enjoy!

Oh, yes it will... this time, I used 1/2 rod, not tubing, so I could machine the pockets for the tubes to make it stronger. Just the 2 main tubes by themselves weigh more than the entire assembly from before!. But, it should help it "settle" down on the suspension nicely, which makes it that much more accurate...

First of all, thanks to you, Pascal and scorpiopab for the compliments... I appreciate any praise from fellow modelers.

Two words as an answer to your question... 1. Planning 2. Variety

I have found that good planning is the first thing I've had to do. By that, I mean, that I have tried to make decisions on whether to use solid rod or tubing, where to "pin" items together, machining pockets to accept rods for better/larger surface contact and when to solder items relative to other item's positions.

Secondly, by variety, I mean what type of soldering tool to use. I am fortunate to have irons, many different sizes of torches and a resistance soldering rig at my disposal. If I'm soldering plate or long runs, I'll use an iron to flow the solder the length of the joint. If it's heavier/denser material or a larger joint that needs alot of heat, I'll use a suitable torch, which gets stuff hot, fast! And finally, the resistance rig is the best way to solder pieces in close proximity to each other, since the heat is concentrated right at the tip of the electrode.

Stay tuned, as the chassis is just getting started... there are a ton of brackets and subassemblies left to be made and added, then it's time for prep, filling, sanding and paint. Then I can move on to other fun stuff like suspension, engine, bodywork, etc. It will be a long process, but the finished product should not only be the only example in 1/8th ever made, but a pretty decent one, at that!

As a quickie update, I have my parents in from out of town this weekend, so progress will be non-existant, which kind of stinks, since we'll be snowed in all weekend! The forcast is calling for 12-18 inches of new accumulation between now and Saturday night! Great building weather, except I won't be able to do any building!:shakehead:shakehead:shakehead

The forcast is calling for 12-18 inches of new accumulation between now and Saturday night! Great building weather, except I won't be able to do any building!:shakehead:shakehead:shakehead

Thanks for following, everyone...

Gary, hope that weather isn't coming our way - again!:disappoin

Just to add some pointers -a good tip for multiple solder joints on one object is to use (say) three different solders with different melting points. Use the high temp stuff first for the major construction work, then use the lower temp ones for additional fittings etc. - learnt that from the jewellery dudes in my class.

There are other soldering tricks, like sweat soldering where the solder is applied first to one piece, shaped then added to the other component before hitting the heat again. This could be used for say the chassis cross tubes (if they are solid). You can sweat the solder onto the ends of the bar, file it down and dress it, then drop it into the fluxed milled hole for soldering. This also gives you the chance to keep the joint cleaner, as the solder is already in place and allows you to concentrate just on the torch heat, rather than holding fiddly bits of solder.

The most important element for good soldering is the use of gravity! In the case of the suggested pre-soldered chassis cross-bars, if the chassis straights are set up so that the cross-bar ends are vertical and the pre-applied solder is 1-2mm thick, the piece should fall into to the hole under it's own weight and squeeze the solder upwards when the temperature is correct. I tend to hand hold a lot of objects during soldering so I can move them around to use gravity, but obviously with a jigged up model chassis that's not easy. It has another advantage as you can feel when it's too hot!:iceslolan

Another tip is to creep up on the the smaller joints by spiralling the torch around the joint gently from the outside towards the joint. This allows more gentle and even heating and stops parts moving around - they will often tilt towards the cooler area, otherwise.

There are also temperature blocking products that create a barrier against the heat for the previous soldered joints - any good jewellery (jewelry) supplies have it.

One more tip, then I'm off! Solder is normally round section when bought on the roll. I often shove it through jewelllers rollers to flatten it into strips. You could use a flat plate and hammer instead, I guess. This allows you to put the flat strips into place on a joint easier and it seems to let the solder go at a lower temp - probably because of it's larger surface area.

Good luck and hope all this drivel makes sense!

Yup, it all makes sense, I use alot of the techniques you talked about... you just went into alot more detail than I did, Lol! I also use alot of heat sinking with clamps, wetted cotton or yellow ochre paste for anything I don't want soldered.

Anyway, I think the weather is headed towards you... well, it's headed off to the east from us, so I guess you may see some of it, eventually... it's really coming down here, right now. About an inch or so an hour, right now! Gotta love it!

I would think your father would see your incredible model and shove you aside and take over. You just might get some progress done after all.

Amen, he could! He was a prototype modeler for North American Rockwell back in the sixties and seventies. We'll see how long we can all stand each other all shuttered up and snowed in, Lol! I may just sequester myself in my workshop and not come out...:):):) The snow's still coming down and it's really starting to pile up quickly...

Hi bwmmech1,

A nice soldering masterclass taking shape there with you and Cinqster - good stuff! Looking ahead, which way are you thinking of going with the engine and gearbox? I'm guessing that we're going to be seeing machined metal sometime soon...

All the best!

To be honest, I have not decided on what material to use for the block, gearbox and rear-end. I will have to make a master for the block and gearbox, I have a basic master for the Salisbury rear already. It will take some work. I like the idea of metal, since it lends a sense of real weight and correct texture. Obviously, the suspension pieces will be machined, along with the wheels and whatever else, but I'm not convinced that the engine and gearbox couldn't be made from resin much easier. Although the texture of sand-cast metal is hard to beat... See what I mean, for every con, there's a pro, and vice-versa. Anyway, I'll finish up the chassis and go from there...

Since everybody seems to be on tonight, check out this website...

Look at the frame photos under the manufacturing tab... this is what my final result will look like, before it's painted. These are the closet to original cars made presently, just incredible craftsmanship... enjoy!

Thanks for the soldering tips...learned a lot! Great progress Garey I love to see it grow. With the engine you have some interesting challenges. Did you consider to solder the engine?

Thanks for the tip, I've seen the Factory Five stuff, but it's no where near as accurate as the Kirkham as far as design of the chassis and materials used for the bodies. A Kirkham is THE cobra replica as far as the cobra owners are concerned, since it's made to all but identical specifications/materials as the original. Factory Five stuff is excellent, without question, but for the exact replica that I'm working towards, I'll stick with the Kirkham references...:):):):)

Well, I took a snow day today, since we got another 18 inches of snow overnight... I thought I'd spend the day in my workshop, but as it turned out, I spent the day with my 2 year old and the wife, which was just as good! We had the neighbors over for dinner, so my shop time got condensed to a few hours after they left. Oh well... the best laid plans, right? I did get the motor mounts done, the trans mount done and the front shock mounts, too... enjoy!

Got a little more done tonight... it's actually starting to look like an AC frame, now! Lots of rear suspension brackets to add yet, but the basic frame is getting closer to being complete... then I get to start on the "birdcage" or superstructure... enjoy!
