Either way, even red locktite couldn't keep that thing from slowly backing out after an hour or two, and I think his application would require something long lasting. I'm thinking that an ungeared CIM like he is planning would make this problem much worse, but that's purely anecdotal.

Ours is slightly too large and ends up sitting on top of the keyway, actually. That combined with a soft steel shaft might account for the good seating, not to mention the accumulated grime holding it in.
