This does, of course, go against all the standard tenets of lathe design. Not unexpected for machines not manufactured with any consideration of lathe design, perhaps. My Rivett sits on two inset ball-bearings at the headstock end and a spherical washer at the tailstock end specifically to ensure that the support stand could have no influence on the shape of the bed. In the case of Gene's lathe it seems quite possible that the head simply isn't straight on the bed. It would be interesting to put a long bar in the chuck and see if it is possible to move the headstock about. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Is your legacy SCM system holding you back?
