I believe that this visual demonstration shows exactly what is happening to a golfer's clubshaft, hosel and clubface when it travels through impact when the golfer employs angled hinging.

Do you disagree?

Jeff.

I appreciate your effort in the visual demonstration. But I think it misses a crucial ingredient: under centrifugal acceleration, the clubshaft bends from the drooping of the clubhead. You can now keep the grip-end of the bent clubshaft on your plane board with the clubhead swinging below the plane board. For a well matched club, the sweetspot should now be on plane too. I have no difficulty envision the rotation of the clubhead around the sweetspot under this scenario.
