OK... I woke up at 3 a.m., was unable to go back to sleep, and had rotocasting ideas running wild in my head. So I did what any other perfectly normal individual would do and jumped online to do some research. Anyway... I ran across this stuff, http://www.smoothonsecure.com/store/...de97aa48340ba8, while looking around. I know it really has nothing to do with rotocasting, but is this what is or could be used for cold casting?
Oh yeah... I did find plans to build a rotocasting machine too.
