Pricer-I just noticed you are in mobile Al. I am just up the road a few hundred miles in north Al. Unless you just want a challenge, why don't you consider re-designing your tumblers. I don't know what scale you are building but why not just make-2-flat tumblers for each end-maybe 1/4" thick and make any kind of design on it you want and pour them in a flat-2- pc. mold. The double tumblers would drive the double drive dogs like you have pictured in your mold. I don't know the weight of your model but the tumblers cast from epoxy should be strong enough. Keep it simple. Just my opinion.

I like that idea. I am curious as to how strong epoxy is and I look forward to testing it. Simple is good.
