Casting/ Tools

I have access to some tool’s as i want to learn how to cast metals to make jewelry etc. The tools are: Tack II spot welder, Jelenko Thermotrol Centrifugal Casting Machine, Kerr Automatic Electro-melt Furnace, Ultrasonic Cleaning Machine & a RayTech Tumble Twin Rock Tumbler as well as a Jelenko LFC Burnout Furnace.

  • which of these would some recommend to myself if I wanted to get started casting things, such as small charms, gold teeth etc?
