Crawler Track Build - American HC230

[Pricer]

Here is a drawing of the resin/Brass structure jig in the bottom part of a two part mold. I am still waiting on 3D parts to be shipped to be used as mold masters. If anyone has any ideas or experience with this I would appreciate any advice I can get prior to getting started. Thanks

Resin Casting over brass tubing frame idea. 3D print a master pattern of the finished tumbler, make silicon mold of master, build brass tube frame, jig the brass tube frame in the silicon mold, add casting resin to mold, remove finished part. Additional part details could be added to the 3D printed part (i.e. Bolts, curved openings, letter, numbers.) to bring the part to life.

Just an idea, one of which I am working towards.
