Help with Hardinge HLV-H tailstock
 

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!

George

They do tend to sock on down tight, especially if you use way oil and
leave them sit for a while. To break them loose, bump with the
carriage.

I tend to keep ATF (which is what hardinge says to put in the pump
lubricator on the carriage) under the tailstock. But the bearing
surface is large and it does still stick if not used for a week
or so.

Which IBM laboratory did it come from? T.J. Watson?

I'm not certain which lab used my lathe, but I believe it was in
Endicott, New York, if that helps.

Thanks for the suggestion about transmission fluid - I'll give it a try.

Thanks

George

That's what the mfr. specs for the pumper oiler that does the cross
slide and carriage. It's already on the ways, I just juice up the
tailstock end with a pump oiler now and again.

When I was putting way oil on it, it would lock down *real*
tight after a few days if it didn't get used. Come to think
of it, I haven't *used* the pump oiler at work that has way
oil in it, in a couple of years.

I also use ATF in my HLV-H.

"The importance of morality is that people behave themselves even if
nobody's watching. There are not enough cops and laws to replace
personal morality as a means to produce a civilized society. Indeed,
the police and criminal justice system are the last desperate line of
defense for a civilized society. Unfortunately, too many of us see
police, laws and the criminal justice system as society's first line
of defense." --Walter Williams
