Re: 7.5 HP Lathe on a 10 HP idler?

The *real* test is to put a heavy chuck (e.g. the typically

spin loose, set for the highest spindle speed (within the safety range
of that chuck, of course), start it at that setting, and once it is up
to speed, reverse it and see what happens. The only more sever test
would be to have a maximum diameter workpiece (which will clear the
cross-slide) the length of the lathe between centers -- or perhaps
reversed jaws and the largest diameter workpiece which is short enough
to not walk out of the jaws without tailstock support. :-)

So, DoN, do you think that with the chuck heavy enough and RPM high
enough, plug reversing the lathe would actually reverse the idler?

(I believe that it is true, based on general symmetry considerations).
