Your answer to my first post ever on this Forum really sailed over my head, which explains the delay to my response. Not that I expect to change your mind on this subject, but I think both you and Homer are mistaken on this point. The vertical hinge pin in 1-L is a hinge pin that controls both the raising and lowering of the arms (primary lever) and the club (secondary lever). What Homer missed about the horizontal hinge is that it comes in two different forms, one that allows the clubhead to move futher away (outward) or cause it to move closer (inward) to the golfer's center of gravity. Every golfer has the option of combining either an inward or outward primary lever along with an opposing secondary lever. Both swing methods are equally effective at producing effortless power and accuracy.
This fact allows the vertical hinge to stay vertical (in line with the force of gravity) throughout these two distinctly different swing methods. I contend that Homer explained his two methods (hitting and swinging) based on his own experience a golfer, in which his preference was for an outward primary lever and an inward secondary lever. He likely felt the effortless power of the other swing method, which reverses the direction of the two levers, and tried to explain it with geometry that involved refering to a vertical hinge pin as an angled hinge pin.
In my opinion, angled hinging can only be used effectively in partial golf shots. I see it as a means of combining horizontal and vertical hinging into a single movement. However, in order to have a full four barrel swing, you must use a combination of pure horizontal and vertical hinging throughout both swing methods.
Believe me, I have the highest regard for Homer's genious and believe TGM to be a monumental contribution to the science of the golf swing(s).

Ray,
I applaud your original thinking on the subject of the golf swing. Unfortunately, we have -- to put it mildly -- 'irreconcilable differences.' Nevertheless, I have assigned numbers to the text of your post and have reprinted them below with my comments in bold.
1. Your answer to my first post ever on this Forum really sailed over my head, which explains the delay to my response.
Yes, it is a mind-bender, but it is also fun once understood. It helps to articulate the words according to the way I have bolded and italicized the typeface.
2. Not that I expect to change your mind on this subject, but I think both you and Homer are mistaken on this point.
You are right on the first point and entitled to your opinion on the second.
3. The vertical hinge pin in 1-L is a hinge pin that controls both the raising and lowering of the arms (primary lever) and the club (secondary lever).
Agreed (but only one arm, not arms). This is the vertical hinge pin -- a pin mounted vertically to a vertical plane -- of the Angled Hinge.
4. What Homer missed about the horizontal hinge is that it comes in two different forms, one that allows the clubhead to move futher away (outward) or cause it to move closer (inward) to the golfer's center of gravity.
There is only one form of a horizontal hinge. It is a standard hinge whose blade is mounted vertically (perpendicularly) to a horizontal plane. In its G.O.L.F. application, this horizontal hinge causes the Clubface to Close Only through the Impact Interval. The action of all hinges are identical on a given associated plane (horizontal, vertical or angled): The blade of a hinge moves in a circle about its pin. The radius of that circle is fixed by the length of the blade. Accordingly, a Clubhead attached to the end of the blade traces the circumference of that circle, and therefore moves no further and no closer to the hinge pin. The center of gravity of the body (Zone #1) has no bearing on Hinge Action (Zone #3).
5. Every golfer has the option of combining either an inward or outward primary lever along with an opposing secondary lever. Both swing methods are equally effective at producing effortless power and accuracy.
6. This fact allows the vertical hinge to stay vertical (in line with the force of gravity) throughout these two distinctly different swing methods.
We have a new player: the vertical hinge. Is this in addition to the two horizontal hinges?
7. I contend that Homer explained his two methods (hitting and swinging) based on his own experience a golfer, in which his preference was for an outward primary lever and an inward secondary lever.
Homer explained the 'two methods' (Hitting and Swinging) based on physics, not his personal experience as a golfer. The Ball is hit with a Lever, specifically, a Golf Club. To put that Club in motion, a force must be applied to it. That force is defined by physics as either a push or a pull. In G.O.L.F., pushing is defined as Hitting, and pulling is defined as Swinging.
8. He likely felt the effortless power of the other swing method, which reverses the direction of the two levers, and tried to explain it with geometry that involved refering to a vertical hinge pin as an angled hinge pin.
Power is a Clubhead function. Hinge Action is a Clubface function. And in any event, the pin you are referring to is the vertical hinge pin (of an Angled Hinge), not an Angled hinge pin.
9. In my opinion, angled hinging can only be used effectively in partial golf shots. I see it as a means of combining horizontal and vertical hinging into a single movement.
Please do not tell this to Arnold Palmer, Craig Stadler or Lee Trevino.
10. However, in order to have a full four barrel swing, you must use a combination of pure horizontal and vertical hinging throughout both swing methods.
Two Swings using two -- no, make that three -- Hinge Actions. Also, four Power Sources that enable the golfer to simultaneously both pull and push the club through Impact. The good news is...you understand this!
11. Believe me, I have the highest regard for Homer's genious and believe TGM to be a monumental contribution to the science of the golf swing(s).
