Peter,
I too have a Record CL3 - had it for six or seven years, but never
experienced this problem. I replaced the motor about two years ago and
struggled for some time to get the pulley off the motor shaft. Loosened the
grub screw and expected the pulley to slide easily. It was only when I took
the grub screw right out of its hole that I discovered a second screw
underneath.
The pulley on the spindle is exactly the same, one grub screw on top of the
other. Tighten the first one down on the spindle, then tighten the second
one down on top of the first. It's the same principle as locking two nuts on
a bolt to prevent them working loose. Loctite may help, but you shouldn't
need it.

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
