I wish I had a gyro to test. As I recall, with one axis of freedom it 
takes an initial impulse to start the swing and an equal but opposite 
impulse to stop the movement. So, there is no net torque to account for 
the 'potential' phenomena. The precession torque to start and stop will 
be in the same direction but orthonormal to both the other torques!?

There must be someone on sci.physics that can explain this.
