I've been restoring a 1938 FW. I bought a new belt and lubed and oiled the machine. Tried a practice stitch on it and the handwheel seems to stick when it gets to one revolution around. Also, I bought new brushes for the motor to replace the ones inside it. One of the brushes came out ok. The other one was stuck and separated from the spring so I had to remove the motor and push the brush out so it could be replaced with the new brush. Put the motor back together and now ... motor doesn't seem to work. Check the wiring and it's all still intact. WTH.... Work for a couple months to get this little guy restored for my grandson. One thing after another keeps happening.
Does anyone have any ideas to help fix these or do I need to just give in and take him to a SMG?
