I have recently purchased a SIP 36" lathe. This has a single bar bed
with a key underneath to align the tailstock. The keyway has quite a
bit of play on it and the side movement of the tailstock is controlled
by a pin, grubscrew and locknut. My problem is how to align the
tailstock and hold that alignment. If I align the tailstock centre
with the drive centre and then lock the grubscrew and pin, the
tailstock is too tight to slide on the bed. If the grubscrew is any
slacker then I get sideways movement in the tailstock and
misalignment.
Has anyone experienced this problem and how did you overcome it ?
