You're right about the oil holes. The parts on the tailstock don't really move all that much. An occasional drop of oil now and then will keep it all in good shape. My tailstock looks a bit different, but pretty close. My AR is an early 1971.
Hi, just reading the threads on Sheraton lathes and found this one and your comment re the date of yours. Is there a way to determine approximate dates - I have a 9" AR serial number AR272 and am trying to work out how old it might be.
