The tailstock on my HLV-H has become virtually impossible to move. I've
removed the clamping assembly and the gib, so that only the tailstock
boy itself remains on the bed, and the thing still moves only with
extreme difficulty. Should I be using some special oil for the
tailstock bearing? Any other suggestions?

(I guess the previous owner- IBM labs - had a similar problem: they
drilled two holes through the body to the bearing surface on the
bottom; one hole is fitted with an air coupling, the other is plugged
with a screw but is, I assume, intended to provide a path for
lubricating oil.)

Thanks!
