I was going to post this thread a while back but changed my mind. But the subject came up in a thread on another forum so thought I'd go ahead n post.

This is is just a FWIW post. The subject is wheel collar loose and wheel is lost.

I have tried using thread locker but even the blue was too strong. The hex wrench, supplied with the collar, rotated inside the set screw. I finally used a ball wrench that was strong enough to remove the set screw.

My solution: I added a small n tight O'ring on the gear wire to retain a loose collar. I tested this using a disk sander with no sanding pad. Wheel horizontal on top of loose collar and O'ring below collar. Ran wheel up to speed and nothing moved during the test. Time will tell how good or bad it works.
