My favorite way to take care of the "locking collar" problem is to just turn
the collar upsidedown, defeating the locking mechanism. The collar works
fine that way and rides nicely on top of the bearing.
I have had another problem with this scheme, however. The collar is steel
and so are the allen set screws. They rust. I have a set screw I can't get
loose in one of these collars.
