I have not seen it, nor know what it is. Quite frankly, I can't afford much at the moment... but I'd like to know what it is and if it confirms or denies my belief that the rear knee, hip and shoulder move into alignment with the toes (or slightly in front of them) of the front foot. Is there anything you can tell me?
A question about that swivel move Brian

mathew,
how about a graphical illustration-similar to the straight right leg explanation?
cheers

Hinging I would assume silver...ok
This will give you an idea of the left shoulder hinge assembly....
Now heres 12 pages with yoda's thread on hinging... lots of good stuff..

Mathew,
Sensational! Truly a Hall of Fame post.
Your graphic does far more than bring out the basic idea of the Hinge Action Concept. Properly used, it holds the key to several of the most important ideas in The Golfing Machine:
1. Hinge Location and Mounting. The governing Hinge Pin and Blade are located in the Left Shoulder and can be positioned perpendicular (Vertical) to each of the three basic Planes of Motion, i.e., Horizontal, Vertical and Angled.
2. Hinge Attachment. When the Primary Lever Assembly -- the Left Arm, Flat Left Wrist and Club -- is attached to that Hinge Blade, it moves in a Circle around the Pin. Further, its Motion through Impact is controlled by (and is identical to) the Plane of Motion of the Hinge.
3. Plane of Motion of the Left Arm Flying Wedge. Thus, the Hinge Mounting governs the Motion of the entire Left Arm Flying Wedge (6-B-3-0-1). Here the Left Arm, the Flat Left Wrist and the Club all lie against the same plane through Impact, i.e., the Plane of the Hinge Blade. If one mentally extends the Hinge Blade in your wonderful illustration to incorporate this entire Left Arm-Club unit, you can 'see' how that unit must move to comply with each of the distinctly different Hinge Mountings. And also, in so moving, how the all-important Clubface is caused to Close Only, Lay Back Only, or simultaneously Close and Lay Back. Then, by holding the Flat Left Wrist in the Feel of the selected Plane of Motion, you gain total control of the Clubface through Impact.
4. Rhythm. Finally, in order to maintain the Left Arm Flying Wedge against the Blade of the Hinge, the Clubhead must have the same RPM around the Hinge Pin as does the Blade (6-B-3-0). Therefore, each of the three distinctly different Pin Mountings will produce a distinctly different Rhythm, i.e., RPM or 'Clubhead travel distance' around the Pin. The 'Closing Door' of Horizontal Hinging produces the longest Clubhead Travel, and the 'Opening Trap Door' of Vertical Hinging produces the shortest.
Congratulations again, Mathew. Homer would be proud!
Holenone,
Hello, I am newbie to these TGM related site and discovered the above thread about the various hinges last night. Your explanations are without equal in understanding the concepts described in TGM. While going through this thread I couldn't wait to get through to the end but was somewhat disappointed in how the thread sort of fizzled out. I'm out to build my own hinge and would be indebted to hear the conclusion of it's message, I know the thread is old but to me it's like it was written yesterday...
Thank you for any help

The first three lessons of the thread discussed the mechanics of the Hinge Action as they related to the Hinge itself. The third lesson ended with this:
"Our next step is to learn how to use your Flat and Vertical Left Wrist to replicate the Mechanical Motion of each of the Three Hinge Actions. The goal is to convert our carefully developed G.O.L.F. Engineering System into your eagerly awaiting G.O.L.F. Feel System. When that happens, you will have gained total control of the Clubface for the rest of your life."
The ensuing Q&A on the TGM and Chuck Evans sites brought out many fine points, including commentary that described how the Golfer's Flat Left Wrist should be used to duplicate the Motion of the Hinge Blade. Alas, to date, there has been no official conclusion to the series. However, you may consider the above post as Lesson Four, how the Golfer applies Hinge Action mechanics to control the Clubface alignment and Clubhead Rhythm through the Ball.
Glad you are back Yoda/
For dual horizontal hinging , the left wrist stays vertical to the horizontal plane(or the ground) from impact to followthrough. It's described as a full roll feel because the left wrist is rotated/rolled in relation to the inclined plane. However, the left wrist doesn't rotate/roll in relation to the horizontal hinge plane, and the hinge plane is the plane to pay attention to during the hinging interval. The hinge pin/blade is vertical to the ground from impact to follothrough. IS the above correct?
For angled hinging, the left wrist remains vertical to the inclined plane. Why is it called a half roll feel, and not a no roll feel?
I think after tongiht, after wading through the Yoda primer and other back discussions, I may finally have an inkling about hinging. Horizontal hinging still feels like one long/large swivel. Isn't horizontal hinging sort of(I know you hate seems as if)like a partial swivel, when compared to the inclined plane? Even though I understand that during hinging, the hinge plane is the focus for clubface control.

The left wrist stays vertical to a horizontal plane for Horizontal Hinging. When you're on the inclined plane, you're actually utilizing Dual Horizontal Hinging and the feel is a full roll.
You are correct: it does remain vertical to the inclined plane. However, it IS called a no roll feel - but the actual motion is a half roll.
It (horizontal hinging) will feel like a little left wrist roll. If you are swinging, "just let 'er rip" and you'll have your dual horizontal hinging.
The Hinge Pin is always mounted perpendicular to one of the three basic Planes of Motion, i.e., horizontal, vertical or angled. The Hinge Blade always rotates in a circle about its pin and remains perpendicular to that Plane as well. This is simply how a hinge operates, i.e., it is the action of a hinge.
In G.O.L.F., the Hinge Actions are named for the Plane of Motion imparted by the Hinge Blade. They are not named for the always perpendicular Hinge Pin. For example, a pin mounted perpendicular to a horizontal plane produces a horizontal blade motion and is therefore termed Horizontal Hinge Action. Similarly, a pin mounted perpendicular to a vertical plane produces a vertical blade motion and is termed Vertical Hinge Action. The same logic holds for Angled Hinge Action.
To clear the Fog, take a pencil and position it perpendicular to the cover of a book. Maintaining that perpendicular position of the pencil, lay the book first horizontally; then stand it vertically on its end; and finally tilt it at an angle. Note that no matter what the plane of the book -- horizontal, vertical or angled -- the pencil remained perpendicular to the book.
Now, substitute a hinge for the pencil. Like the pencil, the pin is always perpendicular to the surface of the book. And the rotation of the blade around its pin is always the same, no matter how you position the book. Only the Plane of Motion differs, and it is on that basis that the Hinge Actions are classified.
DDL,
In order:
1. Your first paragraph is correct. Congratulations!
2. Each of the Hinge Actions has its own distinct Feel and Clubface Motion through Impact. You are confusing the two, i.e., the Feel of a Motion with the Mechanic that produced that Feel. Contrary to your statement, Angled Hinging is described as having a No Roll Feel. The Half Roll you mention concerns Angled Hinging's Half Roll of the Clubface through Impact, i.e., halfway between Close Only and Lay Back Only. In other words, the No Roll Feel produces a Half Rolled Clubface. And vice versa.
Similarly, Vertical Hinge Action has a Reverse Roll Feel and an actual No Roll (Square or Lay Back Only) Clubface alignment through Impact. Horizontal Hinging has a Roll Feel and a Closing Only Clubface (Full Roll).
3. You are again correct. Horizontal Hinging causes the Flat Left Wrist to Close in relation to the Plane Surface and accordingly, the Clubface to close in relation to the Plane Line.
In Dual Horizontal Hinging, the Left Arm is the second ("dual") hinge. It is "attached" to the primary Horizontal Hinge (that controls the Clubface alignment) and serves as an Angled Hinge that lowers the Club vertically onto the Inclined Plane (that controls the Clubshaft alignment).
The Golfer using Horizontal Hinge Action (a Closing Only Motion of the Clubface) is almost always also attempting to maintain the Clubshaft on an Inclined Plane. Therefore, for all practical purposes, the two terms -- Horizontal and Dual Horizontal -- are interchangeable.
The only exception would be with Putting and Chipping, where at the Player's option, Horizontal Hinging can be produced while maintaining the Clubhead directly on the Target Line, i.e., in a Vertical Plane of Motion. Because such a procedure eliminates the Inclined Plane, there is no need for a second Hinge to control an Angled Plane of Motion. Hence, Horizontal (Only) Hinging is the designated Variation, not Dual Horizontal Hinging.
