I picked up a free treadmill a while back and pulled the motor for upgrading my lathe. Last night I decided to do a little work on the motor in preparation for the transplant. I pulled the flywheel off. Then the motor face cap, which had very large skirt that needed to come off. I was able to try out the outside jaws on my mini lathe chuck for the first time. It worked out great. Now I just have to figure out the pully system.
