But the ram is not worn. It has constant diameter over its
whole length.

OK, Jim, I know you are no dummy. What *is* worn? If you have a funky
worn bore in your tailstock body then I vote for boring and resleeving.

If the bore's OK but the ram is worn then I vote for plating and then
regrinding. Tricky, that, because you don't want to plate the ID taper ..
