Daryl,

Reading it as Homer wrote "your bolding" in post 32 it just further proves my point.

With zero #3 in basic motion one can employ any of the three hinge actions the clubhead will always finish in the same spot at follow through (both arms straight approx. two feet through) because of zero #3, but the face can be laying back (vertical hinge), closed (horizontal hinge), or closed and laying back (angled hinge). These follow throughs reflect the clubfaces motion through impact and seperation. As edz pointed out the essence of Chapter 2.

Now Zero #3 can make the plane steeper which could make a Vertical Hinge easier to achieve than a Horizontal, but still all three can be achieved.

I know this because my machine can produce these shots, and I've taught it and seen it taught by many of the finest Golfing Machine Teachers in the Land!

B-Ray,

I appreciate your response. I do understand your point of view that one can simulate the Clubface motions associated with the three basic planes while zero-ing out the #3 Accumulator. I don't doubt that you perform this flawlessly and I've seen it done by others as well. I’m not an instructor but I understand the need to teach Hinging in an understandable way.

I’m struggling with two separate issues with naming this demonstration – “Hinge Action”. I'm not opposed to naming it Hinge Action for teaching purposes but I don't think that it's Hinge Action exactly by the book.

First, we all agree that with Zero #3 Accumulator, “all Lag Loading and Hinge Action have Angled Hinging Travel AND Rhythm”. Second, we also agree that the Rotating Shoulders impart “Roll” (closing) to the Clubface.

In your demonstration, Basic Motion prohibits shoulder rotation, “Roll” as we know it, and Zero #3 Accumulator allows only Drive Loading and Angled Hinging Travel and Rhythm.

We have the term “Swivel” which is a rotation of the wrists not dependent on shoulder turn. So, we have the warning; "intentional use of zero accumulator #3 can be useful while unintentional use can be hazardous". I could be wrong, but to me it means Unintentional use (zero acc #3) can be hazardous because Hinge Action must be replaced by a "perfectly timed Swivel" if Hinging other than Angled is attempted.
