Smoking the mold cavities
We tried disk brake high temp lube on the sprue cutter and locating pins. Applied just a tiny bit to a hot mold using a round pointed toothpick. The lube says good to 700*F temp.
It was working dandy until the lead pot heater quit. Have ordered a new pot and repair parts for the old one.
Have had great luck smoking the mold cavities with a candle flame. Most of the 6 slugs drop free and seldom require tapping the handle hinge pin.
Was making 230g 452 with the Lee Truncated Cone gang mold, and Lee 188g 312 1R, sizing to 310 and lubing with my old 450 Lyman and hard red wax that came from a local caster. A heater is required so made one using 1/8" aluminum mounting plate that sticks out the back side with a garage sale clothes iron for heat. Works OK. The wax likes around 100 to 110*F to easily flow.
