I've yet to explore some other options like using the back gears when turning. I know it builds torque but in addition to engaging the back gears I have to also change belt location from countershaft to spindle to get spindle rpm to recommended level. That's for another day.

Jerry,
With a given motor and motor RPM, torque delivered at the spindle is inversely proportional to spindle RPM. If you have the belt positions selected to give the desired spindle RPM in direct drive, then shift into back gear and change the belt position so as to get back to the exact same spindle RPM (assuming that this is possible with the available pulleys) you will actually be delivering slightly less torque to the spindle than you were in direct drive because of losses through the back gears.
