I've had this issue before, and it's rather annoying.
On my large 5/8 drill chuck, when I try and turn a stopper, I will sometimes have the chuck fall out of the taper. The taper stays in the lathe, but the chuck head separates.
I've tried cleaning it, blowing it out with compressed air, wiping down inside and out with mineral spirits, and then seating it with a rubber hammer...and it will hold until some pressure makes it slide out again...
No signs of burrs or debris inside. Is there some trick I can try? I'm almost ready to epoxy the two together - but would rather not if possible..
