Hi, i am mounting a bowl blank on a worm screw but I can’t get thenscrew alined and it comes loose when I screw the blank on. I have a G3 chuck, the screw has a flat spot on the bottom, the part inside the jaws, but I can’t see a corrisponding flat on the chuck and the instruction are no help. What am I doing wrong. Thanks Mike

The flats on the worm screw align with the jaw slides (not the jaws), The ends of the jaw slides are flat.
The easiest way to me is to have one jaw top side up (12:00), then turn the worm screw with a flat side up and insert.
Tighten the jaws almost all the way and pull the worm screw out and then fully tighten the jaws; this will insure the screw is fully extended and can not come out any further during use.
