Anchorman, Keep in mind that these universal motor rotors spin in the range of 10 to 20K RPM. Be sure your coating operation spreads the film evenly over the whole winding scheme. If you don't, you may end up with an unmanagable thing that won't sit still. You could stick the rotor in the lathe and spin it slowly while you spray on the coating. Aerosoling epoxy might be a problem. The coating could run/droop during the bake process. If you have a rotissory attachment for your oven, now would be a good time to break it out. If you dab on epoxy in hopes that it will fill in and adhere to the windings, do a test on some wire strands and bake them. When cured, verify that the epoxy cant be broken out of the wire strands. I have not had good luck with epoxy adhering to enameled wire. Whatever you do to one side of the windings, regarding adding weight, you must add to the other side to compensate. Keep in mind also that if the fix material is not adhered to the existing windings, it can break away from the adjacent windings and pull the loose wires even further out. When you get the motor back together, set it up with a motor speed control and bring the speed up gradually to verify that you have performed an operable fix. Good luck. WWQ
