If the motor is spinning at 350 RPM, then the final output will rotate at
about 0.17 RPM (with a 1:2016 reduction), ignoring friction losses. That's
pretty slow.

If you ignore frictin losses then the torque output will be 1210 ft*lb!
(assuming a motor output of 0.6 ft*lb) If you could fit on a Phillips head,
you could try driving screws into solid wood ;-)
