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?
