I got a used 6 1/4" three jaw chuck a couple of years ago. It has always
required a lot of effort to open or close. I took it apart and cleaned and
lubricated it when I first got it and everything appeared normal. I've got it
apart again now and the all the jaws are tight in all the slots of the body;
to the point I can't move them with my hand but have to rap them with a
soft-faced hammer.

Question: If I lap the jaws to the body am I going to regret it later?

Thanks.

Paint it up with a magic marker and run things through. You'll see what and where
quickly.
