Machinable Wax

Has anyone used machinable wax as the basis for a female mold? I'm considering this as an alternative to absurdly labor intensive male plugs made from fiberglass and foam, and would like some input before I spend a couple hundred on wax.

Interesting idea. If you're talking about making a female mold, I assume you're going to shape the wax w/ a CNC mill or router. The fact that the wax is reusable is attractive.

Is your plan to then make a positive from the wax negative and then construct mold halves the traditional way w/ a parting board, et al?

If you're using anything exothermic (like epoxy) to make the positive, you're probably going to have to control the cure so that the epoxy kicking off doesn't melt the mold. Slow hardener? Ice?

Please post your results. I'd like to give this a try as well,

Mike
