Yoda,

I think you have said that when actually making a golf swing, the hinge is actually in the left hand, not in the left shoulder.

Where is the second pin located, that changes things from Horizontal Hinging or Vertical Hinging, to Dual Horizontal or Vertical Hinging, respectively?

Is the second pin just the left shoulder at our bent-over address position?

......

There is no hinge pin in the Left Wrist for Clubface control per 2-G. There is a hinge pin in the Left Wrist for Clubhead velocity control per 2-K.


What I said about the Left Wrist and Hinge Action is that, while the Hinge and its Pin are located in the Left Shoulder, the player's control is in the Motion that his Flat Left Wrist makes through Impact and the Follow-Through. Here the educated Flat Left Wrist reproduces the desired Clubface Motion --Close Only, Lay Back Only or Simultaneously Close and Lay Back -- by remaining Vertical to the Associated Plane of Motion.

The second pin you mention -- the one that attaches the 'Shaft' of the model Club to the Hinge in the Hinge Apparatus you built -- is there solely for the purpose of lowering the Clubshaft onto the Inclined Plane and then maintaining it there throughout the Impact Interval. Hence, it should be considered a secondary hinge controlling the Clubshaft and not the Primary Hinge controlling the Clubface.

This Pin can also be visualized at the Shoulder as illustrated in the two pictures (10-10-D and 10-10-E) on page 167 (6th edition). Note the double-headed arrow located on the Left Forearm in each illustration. The arrowheads indicate the Vertical motion of the Arm that allows it to lower from the Shoulder and thus postion the Clubshaft On Plane.

Also note that it is the large middle "dot" in the middle of the blade of the Primary Hinge that attaches the Angled Hinge and permits its Vertical motion toward the Plane. That "dot" is a vertical (to a wall) pin that permits the Angled Hinge (the Left Arm and Clubshaft) to belowered vertically to the Angled Plane.

The other two dots on the blades of both the 10-10-D and 10-10-E hinges are somewhat misleading as they are not 'fixed' and hence they do not restrict the Vertical motion of the Angled Hinge. This is in contrast to the three small dots on the blade of the two Hinges of 10-10-A/B that are 'fixed'and that therefore do not permit the Vertical motion of the secondary Angled Hinge that is necessary to produce the On Plane Clubshaft of the Dual Horizontal and Dual Vertical Hinges. Note that the pins are similarly fixed' in the Angled Hinge of 10-10-C. However, the Clubshaft is positioned On Plane none the less because the Angled Hinge Pin itself is positioned Vertically to the Angled Plane.

I know this must sound very confusing, but it just can't be written any clearer than I have done it. We'll be covering these ideas in the thread, and as your understanding evolves, come back to this post and try again.

I plan on getting Lesson Four posted tomorrow, and we should move along pretty quickly from there.
