I have always maintained that there are two SEPARATE forces that induce angular displacement of the bat. (1) The CHP - generated from body rotation. (2) Torque - generated from the push/pull actions of the hands and forearms.

If I believed a "circular hand path can only be created by torquing the bat handle", why do you think I would add the steering wheel knob to the bat (which eliminates torque at the handle) when demonstrating a productive CHP.

Jack,

Now you've really lost me. Are you saying that the circular hand path is created by applying forces to the bat handle?

If so, please try to explain what's happening at the handle. I'm not trying to misquote you, but my impression was that you believed that bottom hand torque was the primary contributor to bat speed after top hand torque had ended. This meant to me, perhaps in error, that you believed that linear forces at the hands were small. Are you instead saying that linear forces are large, and that both torque and linear forces are important?
