Just thought I would pass this along. I bought a fence plyer/hammer and tried using it to remove the copper from stators . Actually it worked pretty good. After I cut the copper on one end with a band saw I put the curved wedge end of the fence hammer in the small openings in the copper wire and hit the flat surface with another hammer.

Be very careful hitting one hammer with another. Hammer heads are hardened steel. Materials designed to be hammered (ie: nails) are soft. This is evidenced by "mushrooming" or bending. When two hardened surfaces are struck forcefully, there will be chipping and flying steel (sometimes into the eye).
Thanks for the tip Mick. I do wear a face shield whenever I am scraping.
Well i can share what we do to get the copper out,To start we take the copper houseing and cut the first half of the exposed copper off useing a band sawTip cut the side off that does not have the wire inserted in it, cut the most uniform side.Then we place the housing in a vise,tip we spray the copper winding with WD or a degreaser,leaveing the wide wineding on form the cut stage now gives you some more leverage,useing a seal puller sold in sears and napa the remaning copper can be pulled out pretty easialy.
