Yes put it in a vise. Use a metabo 6" angle grinder. The thing that really slowed you down was getting the copper out of the steel. For that use a punch and a hammer. A chop saw would speed up the process even more. Im thinking 3 min to remove the ends/rotor and 2 min to remove the copper from the steel. So 5min total.
watch this video from 2min-4min
wow. 50 cents per pound for electric motors? i called today they said 25 cents a pound for copper electric motors and i think 11 cents a pound for aluminum. is that how much its dropped since the original post?
