I Picked up a used Albrecht 1/8" to 5/8" chuck. Seems to operate very
smoothly, but if you close it down to near 1/8", the jaws become
slack. An internal acme type threaded screw moves the jaws in and
out, and when the chuck is set to less than about 0.135", it reaches
the end of it's engagement. It's easy to reengage the screw, and it
works fine on larger diameters, but this seems wrong. Is this normal
for this chuck? I have a 1/32" to 1/2" Albrecht and it does not have
this issue with drills below it's minimum, ie the jaw screw does not
disengage at it's min diam. setting. Can it be adjusted or is the
screw damaged?

It's because it's a METRIC 1/8"

I thought the metric 1/8" was 118 thou...

It should not be.

Is it possible that someone re-ground the jaws' mating surfaces
to deal with wear, and this results in them extending too far out?
Perhaps even someone put jaws for a 1/2" chuck in the 5/8" one?

Good Luck,
DoN.

That's a thought, I'll have a look too see if they have been ground.
I think the jaws in the larger chuck look wider, but I need to verify.
