Have a Lyman bullet lube heater, use it under my Star Sizer, however, my heater doesn't a temp control. simply a cord that plugs into the electric. Am wanting to control the temp of the lube heater, anyone have any plans for a DIY temp control with the wiring. With the lube I am using, if too cold, it won't flow, and too hot and I have a liquid mess all over the rounds. Any help here?
