I wonder if one could just pour a couple of gallons of epoxy casting
resin into a box, then send that off to the machine shop -- if you can
do it without bubbles you certainly have something that you can polish
to a high shine.

You could pour your own. But I think it would be cheaper to buy
something ready made. The patternmaker suppliers have a number of
products designed for CNC machiningto make patterns, plugs or molds.


A pattern shop in your area would probably be your best bet for the
machining and help in getting type of finish you need.

The one quote that I got (from Freeman) was more than the cast aluminum
