The Un-Centered Angled Hinge

Yoda, I'm still having trouble seeing the Slice tendency of the Angled Hinge. I keep looking at Mr. Kelley's illustration 2-C-1 #3, wondering how the illustration would differ if it were Angled Hinging. And although there is no Layback with a Horizontal Hinge, isn't there some Layback with a Dual Horizontal Hinge? (Maybe I'm asking these questions too soon, since we haven't even reached the "Dual" part of the lesson yet.)

You'll see this more clearly as we go along. Actually, you'll really knowit when you can Feel the difference between the Horizontal HingeAction and the Angled Hinge Action. And that won't be long now.

For now, the answer you seek is that the first Clubface in 2-C-1 #2A/B and#3 would be more 'Closed.' This is because the Angled Hinge is producing aClubface 'closing' that is less than that of Horizontal Hinging. Per 1-L#17, the Clubface must be square to the Line of Flight at Separation.Therefore, with Angled Hinge Action it must be more Closed at Impact to allowfor that 'Opening.' Otherwise, a slice will result.

Don't expect to understand what I'm about to say, just throw it in yourIncubator in hopes of some future feathers. In Horizontal Hinging both theShaft and the Clubface are rotating around the same Center. Hence, there is aCentered Motion and the Point of Compression is maintained. However, in AngledHinging, the Clubface is constantly staying vertical to the surface of theAngled Plane (and more and more open to the Plane Line versus HorizontalHinging). And this motion has no center. None. Thus, the basiccharacteristic of the Angled Hinge Action is a slicing, uncentered Motion.This means Compression Leakage and "Fore Right!" unless compensatedby closing the Clubface at Impact Fix per 2-J-1.

This 'Closing' of the Clubface at Fix will be more with the longer Clubsbecause the Ball stays on the Face longer. And more time for the 'uncentered,slicing tendency' to be exaggerated.

Finally, there is no Layback with Horizontal Hinging, with or without the DualHinge arrangement that permits the Horizontal Hinge Action to be executed as onOn-Plane Motion.
