You state that I am wrong. That may certainly be true. However, I would better appreciate that fact if you provided a detailed explanation.

I already did. Incubate my reply -- posts don't have to be 1,000 words long to be precise -- for more than a nanosecond and get back to me. In retrospect, in addition to 10-10-D and 2-C-1, also study 2-F, 2-G, 7-10, 6-B-3-0, and The Glossary (specifically Flat And Vertical Left Wrist; Hinge Action; and Rhythm).

In 10-10-D, Homer states that the angled hinge keeps the clubshaft on the inclined plane while the horizontal hinge keeps the clubface turning. That's exactly what I was demonstrating in this short video.

. . .

Where is my error in the interpretation of 10-10-D?

For starters, you did not demonstrate 10-10-D (Horizontal Hinging on an Angled Plane). Instead, you demonstrated 10-10-C (simple Angled Hinging). But, even Angled Hinge Action demands Clubshaft Rotation. Only with Vertical Hinge Action (10-10-B/E and 2-C-2/3) and its Zero #3 Accumulator Action would your argument have any validity.

You also wrote with respect to the clubshaft-: "it must rotate to and from the Plane of the Sweetspot." How does the clubshaft rotate to/from the plane of the sweetspot when Homer stated in 10-10-D that the clubshaft is maintained on the inclined plane?

Read the caveat and detailed explanation in 2-F, and you will understand. On second thought, maybe not. In a pinch, re-read the third sentence of the second paragraph in my post #125 above.

Neil - let me ask you a simple question. If you can imagine the clubshaft twirling on its axis so that the hosel rotates around the sweetspot, can you please provide photographic evidence of exactly where in the golf swing this phenomenon is happening? Thanks.

Neil has given me his proxy, so allow me, please . . .

"What I said is a fact. And anyone who understands Sweetspot Plane versus Shaft Plane understands that fact. In person, I can demonstrate it in five seconds. Regarding photographic proof, it ain't my job to jump through your hoops."
