The commutator on the motor looked ok from this angle. I did not want to take the motor off and dis-mantle it last night. The one brush that I took out looked pretty good, as well. It certianly was not oily and the motor did not smell when I ran it. Nor did it smoke. Both very good signs.
I did put a little grease in the motor grease port.
Tomorrow I have to go to Albany again. I have to pick up a long bed 301. I really want it for free motion quilting. There is also a vintage Monty Ward there that I may be able to pick up. Those machines, I believe, were also Japanese made machines. It may be a good one.
