keyed chuck on that machine.

I've been pretty much spoiled by keyless chucks.
I'm trying to decide whether to buy a keyless or
keyed chuck for a lathe. If I'm just drilling a hole,
keyless is just fine. Putting a tap in the keyless
and tapping wouldn't be a problem because you are
still going forward. But when you put the lathe
in reverse to remove the tap, would the tap
loosen in the chuck? I would assume that there
is less resistance pulling the tap out, so maybe
it wouldn't loosen. Also I assume if it did
loosen, the worse that could happen is I'd
have to remove the tap by hand.

So I'm looking to those with the experience
to help me decide.

Thanks,

Occasionally the keyless chuck (Albrecht)loosens up when reversing.
All I do is put a little tightening torque on it by hand while reversing
and it holds fine. I'd never give up the keyless just for this reason.
