We were talking in another thread about fillers and sculpting etc, thought I'd post this. I'm using a spare Lotus 72 tub to create a car built by the Fejer Bros in Toronto. I'll give some background to that later.
So the Tamiya 72 before I started:
I want it shorter and not tapered in at the rear, so cut off the back end, added a heavy styrene sheet for the rear bulkhead, thin sheets for the side and various diameter rods as solid backing. Everything is held together with thick gap filling CA, not cement, and slightly oversize so it can be sanded back into shape:
Some CA is used to fill any gaps, sanded and really very little final filling needed. This one got Bondo Spot Glaze, apply/sand/repeat
Simple little modification but this way it's nice and solid to handle and no shrinking down the road.
I got it to the primer coat stage about 1 1/2 yrs ago and shelved it for a while, will post some recent pics later.

This looks interesting.... Here's a couple of links about Chinook single seaters
Oldracingcars is incomplete in a way, there was a MK12, and it's I believe the one in the second link. I know this because, as a kid growing up in Toronto, I used to hang around the shops and generally be a pain in the rear. The Fejer bros built another car, when I saw it, it had a nose mounted rad and I thought it was a Lotus 70. But Rudi said it was a Chinook, Lotus suspension (which they always used), and was for George Eaton (I think, maybe wrong on that) to run in the new USAC road racing series. Built to USAC, not SCCA specs. Well the USAC series never materialized and the car just up and disappeared. If you took that car, moved the rad from the nose to the sidepods, made a new chisel nosecone, you'd have the car Mike Knittel found in Buffalo. I think somebody started to convert it to a F5000 and then gave up. Either way, Mike has one gorgeous race car!
I got this weird idea I'd try to build what I saw in the shop, from memory and pics of Mike's car, simply because I doubt anybody has ever done it. Well, it's more work than I thought! 
Yes, I am certifiably nuts.

LOL...Thanks for the info bubba. I don't think you're nuts. I hope you keep building it!
Thanks for the links Paul. There is a lot of good build photos in the second link for sure.

Some progress pics I took. Tub complete, some paint, I'm happy enough
The bulkhead needed a recess to allow the Ford to nest in a bit further forward. So far I've just drilled the engine mount holes. I'm engineering this thing as I go along.

I kind of treated the front sub assembly as a separate project. How to convert a 72 with inboard brakes and torsion bars into what is basically a Lotus 70. Well it took about 2 months. Parts from whatever worked that I had in the bin, plus some steel pins and some aluminum tubing. Paints are all various Alclads and a bit of Mig metallizer rub. The spring/shock units do rotate, the springs work and it steers, all of which is sheer luck. I tried to be authentic as I could, even has Lockheed brakes! The battery and water tank went where I would have put them if it was my car - no idea where the originals went.
It'll do (I think) lol.

Thanks guys. It's a long term one, at least by my standards. Bill Brack had a 70 with Castrol sponsorship so I stole it for my car, I just like the look of it and it's period correct. Printed my own decals on my wife's printer since mine bit the dust (again), not great but they'll do.
The three main bits, more or less ready to go together
That's where it's at for the moment. Stay tuned for further updates many moons down the road at this rate.
cheers Paul

That's looking real good Paul. I'm with you on the Castrol sponsorship. It looks cool on any car.

Nice. A Castrol livery looks great on everything.

I finished the beast. Not the best model ever built, there are flaws, but at least I know there is only one in the world, lol.
Any questions I'll gladly try to answer them.
cheers
Paul

Now that is very, very cool. And unique, as you say. Everything i build has any multitude of flaws. Fantastic work on this one. I think it looks very legit.

Great work. Where did you get the engine in this scale?

Great work. Where did you get the engine in this scale? Thanks.
texas3dcustoms supplied the engine, the intake and exhaust headers came from Shapeways.
The supplied engine, alternator location modified, with the supplied 4BBl intake
I modified the oil pan to dry sump with external pump
grafted the shapeways Hilborn setup to the Ford intake
scratch built the rest of it
