I adjusted the COG Orbits to Intersect at Low Point in the Lower 2 Illustrations and depict one Ball Location behind Low Point and the other about 5 inches behind Low Point.



This doesn't make any sense because with each club in the bag, the COG of the Clubhead is progressively higher or lower. So, Soling the Club at Address and taking out the slack in the machine will give you the precise COG Orbit for each Club. So Playing the Ball 1.5 inches behind Low Point in the top Drawing seems to agree with golf club design and Geometry of the circle.

The Bottom 2 illustrations require the Player to raise or Lower each Club at Impact Fix and Address to different heights above the ground to align each clubs center of gravity to one another. This also provides a startling revelation. When the Ball is located 5 inches behind Low Point and resiting on-the-ground, then the clubhead will always strike the ground before the ball is struck. This can be augmented with Shaft Lean however, as the shafts lean progressively forward, the Impact Contact Points once again become the same. Hmm?

The Drawings also illustrate that when the Ball is located 5 inches behind Low Point, the Clubhead will practically scoop a divot deep enough to sod your lawn. That can't be right.

Also, and very important to current TGM bashing discussions is the issue of clubface closing. I've contended that it's not the purpose of Hinging to close the clubface, but that Hinging only determines to which associated plane the clubface closes in relation to... Locating the Ball 1.5 inches behind low Point however will show that the Clubface needs approximately 1/10 of a degree of closing to sustain the Line of Compression. Hmm? Certainly that's less than the Normal to Path Closing ratio.

The Physics, Geometry, Golf Club Design and Homer Kelley are beginning to converge for me. It's becoming increasing clear that the purpose of inclining the Striker is for Trajectory by controlling the Rebound Force, the Purpose of Locating the COG of the Clubhead is in order to make the inclined striker contact the ball at progressively lower points on the ball to cause progressively higher rates of spin and the purpose of locating the ball 1.5 inches behind low point for every shot is to allow all of this to occur. The Geometry of the Circle and Hinge Action only needs a 1/10th degree of closing to make the ball respond to an angular force as it would to a linear force.

There's not much science here. This is pretty simple stuff. The Complexity doesn't rest with understanding the simple Science.

This is going to be a fun project. But, I'm going to wait and listen to comments and I will continue to doubt myself.
