This is my last post on this thread unless something really burns me.

Forget about a human golfer for a minute. So there are no hands and therefore no grip.

Go to Mathews animation 422-1-L_Hinges_LBG (I'm not sure how to post the link). Stop it at the 2 sec mark. Cock the "wrists" (its not drawn on there but imagine a hinge pin half way down the arm....just like the golfers flail 2-K#5 Vertical wrist motion)

As soon as you cock the wrist, the clubshaft no longer points as the plane line. That is what I have been trying to say all along. How do you horizontal hinge and cock your wrists and stay on plane all at the same time? I tried to rationalize it with wrist turn (I think Yoda has also referred to it as startup swivel)

So there are only 3 paths forward:
a) someone acknowledges my point.
b) someone tells me why I am wrong (please!!!)
c) I call enough enough and move on from TGM, being all the wiser for what I have learned the last month.

Thanks.

I sense some confusion re: horizontal hinge. A concept that is easily confused.

I agree with bucket, also some confusion re: #3 accumulator.

The simplest way to understand the horizontal hinge is to first see that it is a hinge motion, like a door, that relates to the left shoulder.

Hold your arm straight out in front of you, back of the hand towards your target. With no turning/rolling, move your arm back and forth like a door, like a lighthouse beam, from the left shoulder.

That is a horizontal hinge motion of the left wrist. It remains verticle to the ground.

Confusion comes in when you take that same relationship of the wrist to ground and put it on an inclined plane. You don't change how it relates to the ground, it is still moving (and in my view 'feels') like it is verticle to the ground, even though it is now on an inclined plane where it will be turning and rolling to maintain that verticle relationship. Viewed from overhead it is still a 'lighthouse' beam.

Do the same drill as before, but stop at any point and lower the hand down to the inclined plane. Notice it will look and perhaps feel like it is turned or rolled, but nothing has changed relative to the left shoulder, and the ground.
