CNC work for the master, mold-making tomorrow, then cold-casting this in bronze and aluminum this weekend. Backfill with 8lb foam and embedded hangars.



Fun project. Next time, probably machine in tooling board and add more detail with the 1/16" ballnose.

So... My first attempt was a bust (see picture). Was trashing it but my family kept pulling it from the trash. Eventually got inspiration to make a new master and starting mold making tomorrow for some alumimum cold-casts.

Weathered the prototype a bit to see what it will look more like. And finished making my mold. Casting this weekend.

All right! 1st Pull from the mold (cold-cast aluminum) Picture next to the Giger book of the same image.

Needs cleanup and weathering but...

So when you cold cast, do you mix a metal powder into resin?

I have not done this yet but I am soon to buy a tooling epoxy kit for making "metal" bucks for vacuum forming. The kit is epoxy with aluminum powder. Apparently you can machine it once cured.

Yes, cold-casting add metal powder to the 1st coat of resin.

Here's an instructional video that shows the process. https://www.youtube.com/watch?v=kghqOKgCEl0

I've used smooth-on 655 (an aluminum filled epoxy) to make molds for injection molding, Didn't do any machining on it however.

Finally finished it up,
Buffing of the aluminum, some light weathering to make the details pop.
