The yellow line represents the ball-target line and also the base of the sweetspot plane.

The red line represents the sweetspot plane line (drawn from PP#3 through the sweetspot ).

The green line represents the clubshaft plane - note that the base of the clubshaft plane is inside the ball-target line.

Do you believe that this practical example is actually happening in a golf swing? In other words, do you think that the clubshaft is traveling on its own clubshaft plane through the impact zone while the sweetspot is traveling on its sweetspot plane?

At Impact, yes.

If your answer is yes - then consider your statement in your last post.

You stated-: "the clubshaft has rotated onto the plane of the sweetspot."

Do you imagine the hosel rotating around the sweetspot?

Yes.

If you imagine the hosel rotating around the sweetspot post-impact, then does the hosel have to leave the surface of the clubshaft plane to achieve that goal?

Yes.

If not, then how do you mentally envisage the hosel rotating around the sweetspot?

Not applicable.

If the hosel has to leave the clubshaft plane to rotate around the sweetspot, then how one can infer that the clubshaft is on its own inclined plane through the impact zone?

Read the bolded portion of the sentence in question from your own post:

I like Homer's statement when he states-: "Except for Impact, the clubshaft is an acceptable Visual Equivalent for both planes, especially if the Clubface is Turned "On Plane"."

Jeff.

"Except for Impact" means exactly what it says. Those words imply -- and I infer -- that otherwise, the Clubshaft is in the process of rotating to or from the Sweetspot Plane.

If you are tempted to answer that the hosel leaves the clubshaft plane in order to rotate around the sweetspot post-impact, then look at the following Martin Hall swing video.

Can I call my lawyer?



Seriously, Jeff, I'm out of time for now. I'll see what I can do later.

Whew!
