1929 Model A Roadster ArtDeco/Coachbuilt/Streamliner -DONE!

Recommended Posts

Well now for something completely different.....   I decided to set my other projects aside and got started on my 1929 Model A Roadster build for the Buckeye Challenge. I really enjoy building the same kit as Andy, (exesivefire) its a lot of fun tackling the same kit and putting our own spin on it.   And since that show is in march, I really needed to get going.

This is a couple weeks of progress, mainly because this concept is a bit hard to explain.. and visually I feel its developed enough to be shown.

So the idea here is to build a classy classic coach-built touring car using the Model A as base.  Maybe a personal street car that would be built in the late 30s by an indy car owner/driver, out of spare parts and some spare time in the metal shop?   I dunno how valid that is.. but at least that's where the idea sprouted from.

Think this but with a Model A roadster as a starting point:

After a ton of planing in my head it became time to start laying things out, and putting the Xacto to styrene. I needed to get the body and shapes into the computer so I can design and draw all of the new components. I haven't invested in a 3d scanner, mainly because they are expensive, and I haven't seen any amazing results from an economical one. So I went oldschool/low tech and just set the body onto a flat bed scanner and scanned it at 100% size.  This gave me an actual size, side and bottom view of the stock 1929 body.

Once that was done I imported the images into adobe illustrator making sure to keep them at 100% size.  In illustrator I was able to draw the new components as lines on top of the images. These lines will be my cut paths for the cutter.  Keeping things at 100% size avoids a lot of pesky/time consuming measuring, basically anything you trace will be cut at that size

Here are the cut paths for the chassis separated into its own file.

And the roughed out assembled frame/chassis

The exhaust will run down each side of this raised center area, the plan is to add some trim and ribbed styrene to simulate some extruded aluminum accents under the car.

The engine will be the miller91 Supercharged straight 8.. So i picked up the last kit available from American Racing Miniatures.. and it is beautiful.

Started connecting and cleaning up the chassis and making motor mounts:

next up fender pod time... took the same outline i drew in illustrator and imported it into my 3d program, and used it as an underlay.

once the 3d model was made, I 3d printed a rough sample to assure my sizing was correct....   2 hours later... this grossness.

everything looked pretty good so i decided to max out the settings and give myself a nice hi res 3d printed halves... its still not that nice, but with some sanding it works..

After I sanded the halves smooth, I added a flange out of styrene, and threw them in the vac-former with some .030 styrene.   Cleaned them up pretty nice.

Then I just had to glue the halves together to make the pods....Here are all the pieces to make a pod:

Then it was time for the integrated trunk that elongates the body and gets that streamliner look without a ton of body work.  Since this is for a contest and is supposed to be based on the 29 kit.. I challenged myself to do minimal work to the actual revell body shell... just a personal challenge.

and here is where this thing sits currently... I'm still assembling fenderpods... but its starting to get the look.

Dude. This is incredible so far, thanks for sharing it with us!
Love the combo of vac-form over 3D printing.
Makes me feel inspired to start a multi-technology, multi-material project. I don't have a 3d printer, but I could be making MDF/bondo and plaster parts and then vacu-forming them.  Had the opportunity to try that a while back, and it worked pretty well.

I agree with everything above, wow its like seeing model building in the future ! !  Absolutely crazy idea ( I expect nothing else from you Eric!  :P )  but it looks really good !  Who would of thought of building this from a humble model A !?!   Looking forward to more mate , keep it going !

Phenomenal. (have to try some new word to describe this) What a creative thread and use of your talents and today's tech. I envy  & thank you and the others such as Chris & Paul in showing what can be done.  I find all of this just fascinating.  Count me as one of your fans too.   cheers, tim
