Your seeing it right, someone in past lathed down the front of the shaft, added threading , and some little brass deally bob on the end. 





Now I have to add a new machined armature shaft to the bucket list. The good news is the motor runs great. Bernie saved my butt designing an armature with removeable shaft. I had to be done that way based on the ball motor frame design. The shaft has to come out first so the field frame and armature could be removed as one.


Wow. That almost looks as if they tried to make a wedge-type retaining system, similar to a Browning taper bushing pulley. Only they did it really sloppy.

Also really cool about the shaft design and disassembly / reassembly process!
