Thanks for comments guys.
I have modeled the front wheels to be printed.



Now I have to find some more real work to pay for it. Rolling Eyes

Every time I look at this I think it wouldn't be much more work to make it run.

Thank you all.
Most of the front axle done, built from steel tube, stainless tube, and aluminum.






Some of the fasteners are temporary.

Some work on the shifter, loosely patterned from a Hurst unit.
Threaded rod runs through entire engine to tie it all together (for strength).
Made of aluminum, steel and brass.







Still some components like stops and clips to be made.

The body is out of the mold. The layup is done with vinylester gelcoat and resin. Two gelcoat layers and
two 225 gram CSM layers. Minimal shrinkage. Mold is brush on silicone rubber(2 coats) and quick plaster jacket.










After a trim,onto the chassis...

Pictures of the body cleaned up. I did the Fiat body at the same time. The next job is to cast the rocker
covers in pewter. Anybody on the forum have any experience with casting metals for models? I have done
a bit of investment casting years ago. Both current builds have SBC engines. I don't want to go with centrifugal
casting as the molds are not viable (cost wise) for 6 pieces. Already have high temp rubber so maybe I'll
just have to experiment......Very Happy

i used to use lead in high temp rubber but its been a long time and the castings were simple one piece items, rekon rocker covers would not be too dificult if u cast them upside down with the bottom open to accept the metal, biggest problem i had was not burning holes in the kitchen benches, found a good sized piece of plywood was very helpfull !

Thanks for comments guys.

dv8v8....you're right about having the cover's opening facing up, I had thought if the 3mm thickness I have
as a wall thickness won't allow the metal to flow (with gravity) , I'll pour it solid and roughly mill out
the back to lighten the piece. The key is to get the right temp for both mold and metal and of course the
vents and runners.......guess I'll have to do it the long (right) way.Rolling Eyes
Lee melting pot and temp gauge VS oxy torch and a $1.97 kitchen ladle........

allan, the front mounted supercharger is to cut down on frontal area as the car will have a full nose section.

doorslammerfan, thanks....glad you appreciate the pics.

I have mounted the rear except shock top mounts. Chassis is oxy welded, some with filler, some 45% silver
solder. Also bent trans mount from 1/2" steel tube. Slot head screws are temp.

Made a few more parts for the roadster. The tires are taking longer than expected. Not much work recently so I can't spend a lot on printing masters for the wheels and tires. Guess I'll make them with what material I have.
Here are pics of progress so far.
























Thanks for looking, more on the body next post.

When you work to this scale I suspect you have to start making decisions as to whether things will actually function or not - we're treading in the gray area between "model" and "miniature"! This is simply beautiful stuff to be savored and enjoyed. I especially like the detail shot of the the join between rim and spokes on the steering wheel... Thanx for all this, David!

DeeCee, thanks, it's a big model so the detail is much easier.

Bernard, glad you like. When you build at this scale, some of the parts have functionality just by having to be strong enough to take the stress of the weight.
These models weigh kilograms, not grams.

A few more bits.....
