".....taking the shaft in the middle and third fingers and 'screwing' the hand to the left."
Jim, did he mean the fingers at the bottom of the shaft "screwed left" under the bottom or
the thumb pad at the top of the shaft "screwed left" over the top?
After all; When you screw you're either moving left at the top and right at the bottom
or right at the top and left at the bottom. In short, when you screw you are pressuring
the shaft in opposite directions simultaneously.
