Induction heating for case annealing?
I don't know if this belongs in here or not but since this is a case forming/reforming section I thought it would fit right in.
anyway.....
Looking at making an induction heater to aid in annealing case necks of rifle cases. Anyone else used this process? Any thoughts? I've watched the videos of those automatic annealing machines and I'm not really impressed with them. One thing I don't like a torch or a dual torch setup because of the possibility of a torch falling over and starting a fire.
My idea is to construct a simple induction heater with a timed cycle that one can set. Annealing as I understand it is a simple yet understood process. Too much heat and you turn the neck cherry red and possibly case damage to the metal and too little heat and the time you have spent doing the process is wasted. If I understand the process you want to heat the neck to 700-750 degrees. There is a compound out there that can be put on the cases and it burned at this heat point showing that the case is heated correctly. Anyway I'm thinking of a simple unit that would allow one to position the heater above a single stage reloading press and put a case in the case holder and simply run the case up into the heater coil to expose the neck to the heater and cycle the heater and adjust the run to in order to get the correct temp reading. Once that happens you simply lower the case and remove it. The second idea is to construct a simple machine that you load with cases and it anneals them and spits them out.
