I have a Clausing 5914 that will drill holes quickly for the first 1/2"

What can be done?
I can imagine boring out the tail stock and pounding a sleeve on the ram.

Well, you take $330.00......


Figure out what's worn. If it's the housing, bore housing & shrink a
sleeve into the housing. If it's the ram only, have metal sprayed only
it and turn back to size. If you were lucky, wear would be limited to
the end away from the taper and graduations. If so, you could cut it
undersize and shrink a sleeve over it.
If both pieces are worn, I think I'd look for a replacement with
fewer miles on it.
