Hi There folks,
I just bought a drill chuck and arbor to fit the tail stock of my lathe. Problem is that the chuck has about 1/16th of an inch run-out. I checked the arbor, no run out there, definitely in the chuck. Is there any way to fix the run out in the chuck? When I drill, only one side of the bit does the cutting and my holes are about 1/16th larger than they should be.
Thanks,
SCOTT

Where did ya buy it? I’d be takin’ it back super quick. 1/16” is WAY too much runout.

That would be the other option – I got it at Busy Bee Tools (Canadian). The gas to get there is more than the chuck is worth though

Sometimes the chucks don’t get seated all the way. Before you give up on it take a hammer, withdrawl the teeth all the way into the chuck, and lightly tap the chuck into the headstock. You don’t want to drive it in so far it never come out. But you do want to hit it so that it reseats itself if it is stuck on something.

This also works on drill presses that have morse taper chucks.

Hammering it in did help fix some of the problem – It is still a bit off just by looking at it by eye – I will try drilling a couple holes this weekend and see how it works. Thanks.

Do the tips of the jaws all align in the same plane ??? It’s possible one jaw got misaligned when it was assembled. They are not at all difficult to disassemble & check.

Just to fill you guys in, I could reduce the runout but could never fix it. Ended up taking the Busy Bee chuck back and getting a more expensive one from Lee Valley. Seems to be alright, a bit of run out still but nothing I can`t deal with.
Cheers,
SCOTT
