I have posted this on other forms, but it’s a good one if you use the Lyman Lube/Sizer. I was having trouble with the lube heater, not sure were I read this, but you take a double receptacle box and wire a light rheostat ahead of the receptacle, this way if the lube starts getting to soft you can back the heat off. You want to make sure it’s a designated receptacle, you would not want to plug your scale into it at reduced current, but I have read that guys had pretty good luck with this on there case auto feed, I never tried it.
I also bought one of those $15.00 wal-mart chuckles drills; with the nylon bore brushes it works great at reduced speed in cleaning bottleneck cases necks inside.
