Reading lathes.co.uk (and I have read all of it) seems to suggest that the traditional approach was three bolts. Rivett just took it to extremes. The Rivett bed is basically a solid rectangular bar. (There is a central slot, but it is half an inch wide, and only about 1/3 of the total bed length.) I think that my Chinese 9x (which, actually, might be an Indian knock-off of a cheap Chinese lathe) has only two bolts, one at each end. However, I have never noticed that it turned tapered, for all its other faults. -- 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?
