Russ, Marty & Marc, Great collaboration! I've been following this project silently, not knowing enough about any of it to comment coherently, but your combined results speak for themselves!

So who is gonna be the first to hit the "PRINT" button?
So we can see if this is going to be feasible?
I tried working on the radiator; to make it useful in 1/16" (solid) and be printable but gave up.
I think the outside should be printed but the "core" made differently.

Marty (and everyone else), I was thinking about keeping the core "solid" (thin walls each side), painting that area black, and applying screen over the painted area. Maybe it would look better with a few layers of screen instead of a "solid" center but I can't remember whether such a radiator would have a "see-through" quality.
A much more difficult problem would be the radiator guard. Even with a bar stock thickness of 1/2-inch it probably would be much too thin to print in metal. Perhaps it could be laser cut ... but what material?

I dont know how to print or draw the file so shapeways would print the "inside" of the radiator hollow.
I also think the radiator is not quite "right" (the tanks) but I need to look into this further....
I "was" planning on doing the guard out of brass strip, but even at 1/16th that is still pretty thin. Unfortunately it is thick in the wrong dimension.
I will be interested to see what suggestions we get for the 1/32 version.
FWIW the guard is .040" x .012" in 1/32 according to measurements from Unc's 1:1 drawing.

Marty:
The Staples here in Williamsburg, Va has an entry level 3D printer set up as a demo. With a couple of larger solid pieces they crank out, the interior is printed as a hollow honeycomb. Quick way to get strength and volume without breaking the bank on consumables. Occasionally, one can see a stray thread crossing the interior of the honeycomb, so it isn't necessary to get it 100% on the inside.

Thats the way the one at work prints using abs melted to form the shapes.
The resolution is not high enough for our needs even in 1/16.
I did a foundation in 1/32 for Jerry that looked good
but being "rough" made it look like formed concrete.

I think in 1:32, you will not succeed to have thicknesses to scale for the guard. Furthermore, the resin may be too fragile and brittle! A Plymouth DL type  The guard  Interior cab will be probably like this   Franck |

Sorry I haven't gotten back to here for a while life and work have been very crazy.
Russ, if you want me to sent you that parts file so you can print it as a test I can do so. If you want when I get a moment I can scale it down and put it on a sprue...or you can. Let me know.
