One of two solenoids which release the brake pack on a large capstan winch has failed. The remaining solenoid is strong enough to retract the brake pack but since the consequence of complete failure is serious, I'd like to repair it and make a backup in case of future problems.
The machine is from the early 1950s and no parts are available. It's a simple coil, about 2 1/2" square by 1" thick. That's from memory, it's still in the machine and no pictures. When I looked at it, I thought it would be straightforward to rewind. Measure the wire diameter, count the turns and buy some magnet wire to rewind. Maybe varnish for stability. Motor is 7 1/2 hp operating at 480 V, 60 Hz. Coils see 240 V as I recall.
Is there much more to it than that? Or other methods I should pursue?
Thanks,
Jim
