I've heard conflicting reports on whether or not a Supernova chuck is too
heavy for a Jet Mini's bushings/bearings. Is the difference in weight
really all that much?

Relatedly, doesn't the method of tightening the Nova put quite a bit of
weight on the bearings/bushings in the first place -so that the Supernova
may actually be better b/c you never have to tighten with force downward on
the headstock?

scratching head

Thanks in advance,
Dave
