This is impressive, thanks for the information concerning the DVD torque.
With sheaves, pulleys,2HP motor driving a two inches shaft mounted with two
pillows blocks in line my friend's lathe only gets down to 226 RPM. This is
enough for him to handle large heavy burls. Changing the belt is
accomplished with the assistance of a foot pedal and loading the burl is
done with a mechanical hoist.

That is true. My 2hp vector drive has significantly lower torque at low
RPM, but then again its got a 3-step pulley to compensate.
The DVR has FAR more torque at the bottom end. At 100 RPM, I cannot stop
it by grabbing the handwheel. Add the fact that you don't
have to change belt positions and you've got quite a capable lathe. I'd
put the DVR against any other 2hp lathe at low RPMs (with
the same 1-to-1 shaft to pulley ratio) in a torque contest.

What would be the torque of an Electronic Variable Speed at 200 RPM.
I am lead to believe that at low RPM the EVS torque may not be as
powerful
as in High RPM. Having two EVS for a while maybe you could comment of
this. TIA
