	The torque of the Precious Plastic shredder is recommended at 70 rpm with a 1/4 hp or higher motor. Using the [[Motor Torque Calculator]], that comes out to 2800 N cm. The stepper motor above meets this specification (for torque, but not speed). '''This would have to be verified, don't trust the specs by themselves.'''		The torque of the Precious Plastic shredder is recommended at 70 rpm with a 1/4 hp or higher motor. Using the [[Motor Torque Calculator]], that comes out to 2800 N cm.

			Let's think about that. 280 kg cm. Or about 3 kg m.

			The stepper motor above meets this specification (for torque, but not speed). '''This would have to be verified, don't trust the specs by themselves.'''

	*Point - cheapest and quickest route to a functional but slow Precious Plastic Shredder is a geared down Nema 23 stepper above for $60, putting out as much torque as a $325 motor/geardown combo of the [[Precious Plastic Shredder]]. The $60 route is functional and appears to have the same torque ('''Verify this experimentally'''). It does allow for industrial productivity on the scale of 100 lb/day regrind very easily - enough for 50 rolls of filament daily. This is enough for 20 pieces of 2x4 lumber		*Point - cheapest and quickest route to a functional but slow Precious Plastic Shredder is a geared down Nema 23 stepper above for $60, putting out as much torque as a $325 motor/geardown combo of the [[Precious Plastic Shredder]].
