But, from what I understand, w does change as you alter the particle 
path of the rotor.

There is a curious phenomena that if you force a gyroscope to move on a 
single axis, it will brake free, stop resisting the torque. I'd 
forgotten but now recall being there playing with a gyro.

See: Captive (one degree of freedom) gyro
http://www.upscale.utoronto.ca/IYearLab/gyroscop.pdf

But this seems to creates a contradiction to conservation of angular 
momentum. Spin up a gyro oriented to the poles which transfers momentum 
to the earth. Push it around on a single axis, broken free from torque, 
180 degrees. Now brake the rotor and you have added even more angular 
momentum to the earth!??

What am I missing?
