The weight only is significant for the=20 centrifugal force on the e-shaft lobe. Richard; Unless I'm mistaken, or misunderstand what you're saying; the rotor does = not rotate around its own center. And the CM of the rotor does not rotate around the center of the e-shaft, but rather follows the center of the e-shaft lobe. Watch the animation on Tracy's web site. Al
