pre-heating moulds
Turk, I don't know if this qualifies as the fastet way to pre heat but I use an electric hot plate with a 5/8 in steel plate sitting on it. The plate is 6"x6". I turn it on at the same time I turn on the pots and I keep a bullet of the same type of metal that I am casting sitting in the center of the plate. If the bullet slumps or melts turn down the temp. of the hot plate. I have used this method to pre-heat 8 and 10 cavity moulds for 18 years and have never warped a mould but it could happen if you don't watch the thing. I usually get perfect bullets on the first cast doing this. Wes
