I Lathed this spool for a Elevator Mechanic. I thenk chopped a Jeep Fish Price motor coupling in half and kept the motor side. I want to attach these together. Any ideas? I tried 5 min set 24 hour cure poxy, but it was too fragile. Maybe i did it wrong? or any other ideas would help. Also I have high machining capabilities, but I am lazy so Macgyver style fixes are preferred.
