hi there paralyzed, ive got an oxy welder at school, that i could easily heat up a pinion. this would make it much more brittle though, would cooling naturally be better, just leave in in a vice or something or would oil be better... not exactly great at chemistry, i just know it becomes really brittle!!
would it be suited when using a metal spur or what?
sorry for these questions,
ryan
