I have a few 5/8-.2 Ballscrews from Mc-masters-Carr I am trying to turn a short stub on the ends 0.47dia. x 1.2 deep. I am having trouble getting a good surface finish on these hardened screws. Now I like to anneal the ends of the screws to make them softer. As far as I remember I have to heat them to a cherry red and allow them to cool of slowly is there anything else I am missing? I am thinking of getting one of the propane torches with the little camping bottle as Fred Meyers sells them to do this (it is also used for soldering waterpipes about $39.-) is this gone work? Any better Ideas?
