Gee, rebuilding one of those armatures must be pretty involved. What about the field coils?

I've seen pictures of them being rebuilt and they do that for traction motors at the Altoona Loco shop in Pennsylvania. I guess a new commutator can be pressed on as well.

If you still have starting trouble I would check the voltage drop between the battery and the starter post when the starter is turning. Those floor switches can wear out and cause problems. A new set of cables may be in order as well. You can have those made by one of the harness makers. The results are better than the DIY stuff.
