Thanks Steve for the information and the advice.
Although gearing up the NXT motors may result in a loss of torque, it sounds
like a good option. Another option might be to control the switch for the RC
motor with one of the NXT motors (which would be controlled by either a
revolution sensor or an ultrasonic sensor). That way if there is a jamb between
the chop block and the blade assembly the NXT system could stop the blade.
2 Questions: Is there a revolution sensor that can interface with the NXT
system (someone at Brickfest told me that the older mindstorms kits had a
revolution sensor). Can the ultrasonic or light sensors do the same thing as
the revolution sensor?

| (...) The NXT motors have built-in rotation sensors, so you could detect a stall condition with no other hardware. You could use the ultra-sonic (distance sensor) or light sensor to detect when the blade passes in front of it, to determine when the (...) (18 years ago, 26-Jan-07, to lugnet.technic)

| Hi Nathan, (...) the RCX rotation sensor should work on sensor ports like all legacy sensors, provided it is supported by the firmware. It would also be possible to build a rotation sensor for the motor ports, i.e. like a NXT motor without the motor (...) (18 years ago, 27-Jan-07, to lugnet.technic)
