Ah, we do neglect that the play in the threads of the loc and set screw will take up whan tightened, so, adjustment will get looser than wanted.

Nothing serious, but, not what the clearance was left at before tightening the screw in the loc.

Just my being through.



Except I leave mine about 1/8 turn looser than I want. Lightly seat the screw, then tighten the poly lock. I have never had one loosen itself this way. It puts more pressure on the screw than you can put on it with the hex wrench. Generally speaking 1/8 turn locks it all tight.
