I've been doing electric motors. Actually my girlfriend of ten years who I sometimes refer to as my wife did four of them, turned in just the copper and we got $36. I still have the steel and the aluminum end pieces. I hope to eventually have something like a granulator to strip #1 and #2 wire. I can use the wire stripper at work but it isn't a good one plus I can't take it home otherwise I'd just strip copper all day at home. We get about a half a gaylord each day of motors. If I could get a faster way to pull the copper out I would be rich. I cut one end off and then pull the other end to get it all out. She'll get a better way soon.
