And, again, we point out that the idea is not that the lathe must be LEVEL,
but level is an easy (maybe the EASIEST) way to be sure both ends of the
bed are perfectly parallel to each other, in other words, without twist.
All I can say is that, after years of fooling with lathes without a precision
level,
the first time I leveled a lathe with a master precision level, it cut more
accurately than I'd ever achieved after hours of working with test bars
and dial indicators.
