Lee melting pot
I also use a Lee electric melting pot bought back in the early eighties. I cast at about 325 degrees centigrade (750 or so f) which is between 6 and 7 on the thermostat. I cast medium hardness lead for .358 swc RCBS twin cavity and lee molds for everything else, mainly twin cavity 454 ball in soft lead. The RCBS takes longet to warm up to casting temp so I leave it resting on the top of the pot while the lead is melting which works fine. Within one or two casts the boolits are coming out fine. If they're wrinkly and shiney I turn the temp up a notch, frosty, I turn it down a notch. I usually flux the range or scrap lead in a big pot on a turkey broiler gas ring using a pea size piece of beeswax and burn off the smoke with a blowlamp. These fumes are a touch toxic.This is then cast into clean ingots for the Lee pot. I don't usually flux the lead any further. I've tried smoking the mold cavities with a smokey candle and also tried a spray of high temp silicone into the holes to aid boolit release, but like tacfoley, haven't noticed much difference. Usually a tap on the hinge pin drops sticky ones out fine.
As to WD40, as an engineer of nearly fifty years I don't think I could live without it!
