Hello again,
I mounted my 3" 4-jaw chuck on my lathe and found that one of the jaws was very tight and after some travel locked. Took it off the lathe in an attempt to determine what the issue was thinking there was probably some swarf in the mechanism but I encountered some issues.
First there are no screws on the back of the chuck as my other chucks have but there are threaded plugs. What I mean is there are four plugs that are internally threaded 6mm. I'm guessing that these are press fit plugs to hold the worms in place and the threads are for a pulling device to remove them, perhaps?
Second the worm that locks has a large burr at the end of the worm and I suspect this is the problem. If I could get the worm out of the body I may be able to use a Dremel tool and grind away the burr. Obviously I don't want to do this while still assembled because I don't want any grit getting into the body.
So, am I right about the plugs and can this issue be remedied or is this chuck junk?
(Should have known better than to get a chuck from LMS. I usually regret my decision to get stuff from them because of the time to get it to me and if anything is wrong, they don't pay for return shipping so I just keep it and deal with it.)
