I worked on the motor some as I'm waiting to complete the cabinet finish and waiting for my parts order. I cleaned up the commutator and put it back together with some fresh motor lubricant. As I mentioned before, when I opened up the motor I found that a carbon brush spring had been ran through the motor, that has left some scaring on the copper section of the commutator.

After cleaning the commutator I put the motor back together. I decided to put the bent up spring and carbon brush in there to see if it worked. After a little bit of troubleshooting I got it to sew under electric power. As one of the brush screw caps is missing I had to hold the spring down with the plastic end of a screwdriver. You can see the spring sticking up in the picture.

I made a conscious effort to make sure I threaded the machine correctly this time.
