................beyond the Hinge before Impact, ................

..........hands will pass the Hinge .............

I truly do not know what "pass the hinge" means . Your Hogan pix passed this question.
I SEE what you are saying

The Hinge is Located at the Shoulder. His Hands did not pass his Left Shoulder Hinge Location until after Impact. If his Hands passed his Left Shoulder before Impact then he would have swung "out to the Right" (down the Angle of Approach) farther than you think is correct, after Impact.

As an aside I dont think the Hinge is necessarily in the Left Shoulder for all shots or for that matter at all times during one stroke.

Take Arnies Hands only putting style , The Peck Basic Stroke the Hinge is the Hands. Or take a Pivot only putting stroke (Putt Basic) .....the Hinge would be in the Pivot Center wouldnt it? For an Arms only (Zone 2 only) stroke the Hinge would be at the Left Shoulder .........How 'bout the Right Elbow for Right Arm swinging? All of this may have implications to ball placement when putting, chipping assuming you want to hit the ball at or fore of low point...low point being underneath the center of the circle.

The Machine of 1-L zeroes the Pivot and the Hands, no? It does its job revealing the underlying geometry of golf , really, really nicely but its a model only with some assumptions inherent, Im thinking. Somewhere in the book Homer talks about the Three Zones and how anyone of them can manipulate the clubface in a manner consistent with the three Hinge Actions....cant find it right now.

Was Hogans Hinge at his Left Shoulder .....yes as the center of his Arm Swing had become the center of his motion by that point in his swing. Let me explain, in Startdown where his Left ARm is pinned to his chest , where his Pivot is Delivering his fully loaded and in tact Power Package Down Plane........the Pivot Center was assuming command and was the center of his motion at that time. The pivot center , a place located somewhere between the shoulders.... Of note is that the Radius , the length of the lever is shorter from Pivot Center to Clubhead, by about half of the left arm actually. When the Left Arm blasts off , accelerates away from the chest (Pivot) the center of the motion jumps to the Left Shoulder and in so doing establishes a longer Radius from shoulder to clubhead...... exactly like a bicycle chain moving to a bigger sprocket wheel. With similar results too..... bigger circle , longer radius, increased clubhead speed at the other end of the radius , lever.

Radius , lever length, another good reason to not put a hanky under your left arm pit.


Uh I hope we're in the Lab here.......... cause who are these dudes in the white coats? Daryl, Mike is that you? Is that jacket for me? Hope its 44 tall........

Great thinking O.B. "Where's the Hinge?"

When we look at the Inclined Plane and inscribe the Angle and Arc of Approach, they're both going inside-out.

Thanks D. Ill show my doodle for that one sometime .....still in its infancy at the moment. Maybe in a different thread.

Yeah the curved Arc is inside out till low point whereas the Angle of Approach just keeps on going straight line , wheel track ..... Homer tried to make it easier to understand with the wheel rim, wheel track thing but I believe he really needed diagrams to explain the Visual Equivalents. The Angle isnt all that helpful, handy if you cant understand it. But that said its still a little bit of Homers genius ....... amazing stuff, really. The guys geometry was so impressive and geometry is best explained in drawings not words. Perhaps the reason the book is such a hard read.

Somebody's gonna shock the golfing world when they draw it all out.
