| 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 per2-G. There is a hinge pin in the Left Wrist for Clubhead velocitycontrol per 2-K.
What I said about the Left Wrist and Hinge Action is that, while the Hinge andits Pin are located in the Left Shoulder, the player's control is in the Motionthat 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 remainingVertical to the Associated Plane of Motion.
The second pin you mention -- the one that attaches the 'Shaft' of the modelClub to the Hinge in the Hinge Apparatus you built -- is there solely for thepurpose of lowering the Clubshaft onto the Inclined Plane and thenmaintaining it there throughout the Impact Interval. Hence, it should beconsidered a secondary hinge controlling the Clubshaft and notthe Primary Hinge controlling the Clubface.
This Pin can also be visualized at the Shoulder as illustrated in the twopictures (10-10-D and 10-10-E) on page 167 (6th edition). Note thedouble-headed arrow located on the Left Forearm in each illustration. Thearrowheads indicate the Vertical motion of the Arm that allows it to lower fromthe Shoulder and thus postion the Clubshaft On Plane.
Also note that it is the large middle "dot" in the middle of theblade of the Primary Hinge that attaches the Angled Hinge and permits itsVertical motion toward the Plane. That "dot" is a vertical (to awall) 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 aresomewhat misleading as they are not 'fixed' and hence they do not restrictthe Vertical motion of the Angled Hinge. This is in contrast to the threesmall 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 secondaryAngled Hinge that is necessary to produce the On Plane Clubshaft of the DualHorizontal and Dual Vertical Hinges. Note that the pins are similarly fixed' inthe Angled Hinge of 10-10-C. However, the Clubshaft is positioned On Planenonetheless because the Angled Hinge Pin itself is positioned Vertically to theAngled Plane.
I know this must sound very confusing, but it just can't be written any clearerthan I have done it. We'll be covering these ideas in the thread, and as yourunderstanding evolves, come back to this post and try again.
I plan on getting Lesson Four posted tomorrow, and we should move along prettyquickly from there.
