Peter, I had a similar problem with my old monotube's pulleys. I went to
Home Depot and found some longer screws (but not long enough to protrude
above the bottom of the pulley groove), then used Loctite and had no more
problem.

I have a Record CL3 lathe that I have recently started using. I noticed
that it was getting rather rattly and discovered that of the two grub
screws
supposed to be holding the spindle pulley in place one was not in situ. I
have since found it in the headstock and replaced it but the two screws
always work loose causing me great frustration at having to keep stopping
to
tighten them up. Has anyone else experienced this problem and if so can
they
suggest a solution. I have taken the shaft apart and can see no obvious
defects but did notice that there was quite a lot of oil on the shaft
(probably due to my over enthusiastic use of the oil can). Could this be
the problem?
Thanks in advance for any suggestions.
Peter
