Gunsmith – Anneal case hardened gun parts for polishing
Friday, May 14th, 2010
This GunTec presentation covers the process of annealing, or softening, casehardened parts so that they can be polished prior to the finishing process. Larry Potterfield, CEO and Founder of MidwayUSA, starts this process by packing each part inside a metal canister, also referred to as a crucible. The parts are covered with charcoal to prevent scaling as they cool. Once the canister is full, it is placed inside the furnace which is heated to 1500 degrees F. The parts are held at that temperature for two hours and then allowed to cool.
