I do a lot of casting for pistol with Lee 6 banger moulds - running 3 at a time, you can go through a LOT of lead. Pot can't keep up even dropping sprues back in pot .

I had a thought, (always trouble !), parts is cheap; what about adding a second heating coil and rheostat?

Should be able to keep up with adding ingots.

This is for blasting boolits for pistols, not too worried about 50 - 75 degree temp swing.

What say you masters of the silver stream and irreverent tinkerers !
