Don't be talking dirty !
I'll be getting my first Lee 6 cavity mold in about two weeks. I see several of you guys mentioned the use of a hot plate to bring the mold up to temp. What kind of hot plates are you using? Thanks, Kurt
Another way to preheat the mold and it's free! Simply place the mold across the top of your lead pot. With some aluminum foil make a small tent over the mold and top of pot. Turn the pot on max, go get some coffee, come back in 20-25 minutes and start casting. You will have good bullets within 2-3 pours at most. Pot heats quicker and you're heating the mold at the same time. Been doing that for at least 30 years.
This past summer we had some work done to the kitchen and were going to be without a stove for a few days. I bought whatever was the cheapest hot plate at Wal-mart (I think $10). When the kitchen was done the wife didn't even notice that I stole the hot plate and took it down to the basement for casting.
Ahh, ok, the open coil type. I had to ask, there are just too many types out there today. Thanks everyone.
Mines a 1000W closed coil unit that I still covered with a piece of 1/4" aluminum. Partly for better contact and I also use it to mount a thermocouple so it's PID controlled. In the past I had used a home made warming shelf. Highest temperature I ever recorded was about 300° of the shelf not mould temperature. With the hot plate/PID set at 390° my mould temperature is about 315° by the time the pots reached it's operating temperature and the FIRST bullets out of the cavity are good both by appearance and weight. The shelf helped but the hot plate is superior.
