My next question is when does it rotate in the backswing and forward swing?

This is why Homer Kelley wants the hands to be Educated. The Hands control the whole Enchilada.

You can turn (to the right clockwise) the hands on plane early- from the address position as the first move. This fans the clubface open as the hands continue the back stroke. You can take the back square for foot or so and then turn them on plane. Either way this is called Standard Hand Action. A turn to the right and a roll (to the left counterclock wise) back to the left.
** see note

The second way is called Single hand action. There is no turn to the right of the hands therefor no turn roll to the left. It is the body turn that makes them appear to turn and roll.

IN EITHER CASE: the hands control the club- the forearms follow suit. I never gave much thought as to what by forearms were doing- just my hands.

Might not be the answer you were looking for but....


Burner- bad pun

** additional info. The Hands turned to the right need a roll back to the left and is part of roll/swivel/horizontal Hinge action/swivel that is used by Swingers. That is why this Standard Hand Action is perfect. Slicers hardly ever fully return the hands via the roll, let alone HH and swivel and finish the pivot.

Blimey, look at the time!
