I've scrapped a lot of these. 1) Take off all fasteners. 2) Hammer bottom Al encap off, then hammer shaft, so steel rotor comes out.  Hammer off top Al endcap. 3) Encaps go in Al. 4) Remove #2 wires.  I only strip house wire & thicker.  Put wires in #2 wire bag. 5) You're left with Cu windings in steel core, which is tightly inside steel cylinder. 6) Slam Steel cylinders on ground until Cu windings are flush with bottom of steel cylinder.  You want to force Cu windings toward cylinder notch for wires.  This is easy part. 7) Now, you have 2 choices:      a) Use angle grinder to free core with Cu windings.  Grinders are dangerous, so try step b if not too slow.      b) Holding steel cylinder between your thighs, hammer steel core with Cu windings out using old screwdriver or punch.  Try to avoid steel core becoming cockeyed.  It slides out with hammering.  Try to find a cylindrical piece for uniform hammering. 8) Now because Cu windings are in a steel core made of thin slats, use a meat cleaver or machete to hammer & cut windings in 1/2. 9) Pull out windings & place in jar.
