This motor came back to life! The hardware store had some brushes, which didn't quite fit, but that's what the sandpaper is for. It spins nicely, no sparks, no fires. I hope to paint the cover pieces so it looks a little nicer. And I have to find a narrower pulley than the one I took from another motor. This one didn't have one and my non-Singer pulley won't line up with the hand wheel.
