Over the years I've read of members here using a standard clothes iron to heat the lubesizer. I've got a RCBS LAM2 and have used a light bulb if I needed heat. I found a cheap iron($3) at Goodwill and decided to try it. I had a length of copper bar 3/8" tk and about 4" wide. After drilling it for mounting bolts, I assembled it to the bench and set the iron on it. I thought I should start at the lowest heat setting. I should have stayed close by so I could see how warm(hot) it was getting. Liquid lube started seeping out without pressure. Oddly enough most of the liquid lube coming out looked like the dregs of some green RCBS lube that I had been trying to use up. I had gotten to the point where most of the lube on bullets was NRA Alox lube. Just a little green in the groove.
Didn't really need that detail. What I'm hoping is that someone can tell be the best way to control the heat of the iron. I guess I can figure out by trial and error some plan for turning the iron on and off. to control the heat to the sizer. I'm hoping I don't have to do all over what someone else has already figured out. ??
