I am trying to find out what lubricants Pultra recommended for use
with their small lathes for the headstock bearings and for the thrust
bearings in the PR2 cross slide. The later is a most impresively
designed cross slide given its size; feedscrews are threaded 40tpi and
instead of the usual bronze nut with a slit which can be closed up for
backlash adjustment, each feedscrew a pair of threaded bronze nuts whose
separation can be adjusted.
Does anyone have a manual for something like a Pultra 1750 or 1770 which
might contain this information?
