The runout means you can't bore a perfectly cylindrical hole using the
quill feed but you may be able to by locking the quill and raising the
table, which is what I have to do. Used machines require a little
understanding, no big deal. How is the runout with the quill
retracted?

Do not confuse runout with deflection. That a quill moves under a given
load doesn't mean it won't run a circle. Running a true circle relates to
the bearings, not the quill fit.
