You got it right Byron. I am pretty pleased with it....since I have had both rotator cuff re-builds....not too good at movement. It is soooo sweet. I can still use it manually. It is variable speed....reversible direction, and controlled with either the adjusting knob....or the footr pedal. Foot pedal will stay where I push it to...or can go all way dowqn for max speed...or down with the heel and go to off or minimum speed. I am liking it enough already..... I think I will forget about the inline axis idea.

Thanks for the replies.
