When the ball and clubface meet, the clubface can either close only (horizontal hinge action), close and layback (angled hinge action) or layback only (vertical hinge action).

I still don't understand this sentence after all these years of the Golfing Machine.

Best Video ever made explaining Hinge Action: http://www.lynnblakegolf.com/index.p...on-part-1.html

Also see video #2 in the series.

When your brain grasps this Hinge Alignment geometry concept, it will be a light bulb moment.

But one thing. It's not a "When the Clubface and Ball meet". It's a "the Clubface is making one of three motions" as it meets the Ball and travels through the Impact Interval.
