New casting pots with built-in PID controllers

[Martini2]

Here is a trick that barrows from both electric PID control and fuel fired. I typically run 20# Lee solid bottom pot / PID controller but also have rigged a propane torch with bit rich flame played on the top surface. This helps minimize oxidation since the mold sprew are also recycled as casting goes. I just like to run one melt/alloy to bottom which can happen readily pushing two 500 gr molds.
