You are right. The up and down and side to side movement is only .007", 3"
from the ram's orifice, with about 10 pounds of force.


After giving this more thought, I came to realize that you likely have
considerable wear-----which would not be restricted to the quill alone. I
can't help but think that you may have to bore the tailstock housing to
re-establish a round and straight bore before attempting any kind of repair.
Otherwise you'd improve the condition, but not eliminate it.

If you choose to do the upgrade, you might consider making the quill from
Stressproof, unless you have access to heat treat and grinding.
