3D Drawing to Resin Cast Wheels
Posted by jaxenro on Wednesday, July 17, 2019 5:20 AM

Quick description of the process for making some resin cast Disteel style wheels for Ford Model T kits

First some examples of the original aftermarket Disteel wheels

Then the 3D model made from the images

Next the masters were printed and cast in brass using a lost wax method

And finally the resin castings made the regular way from the brass masters. 

The process is a little expensive up front but now I can have as many cast as I need plus even sell a few to offset the cost. These ones fit the AMT 1927 T Touring kit tires and the like but I can scale them up easily enough to fit the new ICM 1:24 family of T kits. One of the advantages to 3D modeling the masters is the ability to rescale the artwork easily.

Hello!

Wouldn't it be good to skip the brass stage and just make castings off the resin, 3D printed masters? After filling and sanding them a little that is...

Have a nice day

It could be done that way. I did it this way for two reasons:

1. Being brass the masters are now good for essentially forever for making new molds as the existing ones wear out without any loss of detail as long as reasonable care is taken

2. Being brass I can use them as masters for vulcanized rubber molds in case I want to do white metal or brass wheels as well. We are working on a Frontenac Model T OHV engine next using the same process and looking at a photo etch frame and suspension (leaf springs) possibly with brass axles, etc. 

Part of my idea is everything I have done in resin I can also do in metal and eventually when the engine and frame/suspension are done I can work up the remaining suspension parts and do a complete Model T chassis kit in metal. The only non metal parts would be the tires, hoses, wires, etc.
