I failed to grind the welds completely, so I just cut the stator ring and then was able to easily remove each laminated piece of sheet steel from the TTR source coil. You shouldn't need to do this unless you are a barbarian like myself.

Removing the TW200 "source coil" from the stator assembly is not to bad. It is not welded in like the TTR coil, so I was able to vise the source coil and then use light taps with a ball peen hammer to slide the stator off.
