Martee,

I know what you are saying here, and I'm not trying to be picky, but since you have raised the issue, I do think it is important to get it exactly right.

The Pivot Center hinge pin is vertical -- not horizontal -- to the ground. Its purpose is to anchor the Pivot, not to produce a specific plane of motion. Thus, it is not analagous to the Hinge Assembly of 1-L #4 and 2-G that controls the Clubface and Clubshaft and their respective planes of motion.

That Hinge Assembly contains two vertical pins, one to control the Clubface and one to control the Clubshaft. The Clubface Control pin is positioned vertical (perpendicular) to one of the three Basic Planes -- Horizontal, Vertical or Angled -- in order to produce a specific Clubface Motion (Close only, Layback only or simultaneous Close and Layback). The Hinge Assembly is then named according to plane of Clubface motion it produces, i.e., Horizontal, Vertical or Angled. In each case, though, the hinge pin itself is vertical to its Associated Plane.

The Clubshaft Control pin is likewise positioned vertical, but only to the Vertical plane. This pin permits the Clubshaft to be lowered (vertically) from either the Horizontal or Vertical Clubface Control Hinge onto the Inclined Plane. No such pin is necessary for the Angled Hinge Assembly because that arrangement automatically produces an On Plane Clubshaft.

The Left Wrist also contains a vertical hinge pin, and it is for Clubhead Velocity Control. It is positioned vertical to the Vertical plane and permits the perpendicular Cocking and Uncocking of the Left Wrist (2-K #5). It does not permit any Left Wrist horizontal motion, i.e., Bending or Arching. However, it does permit Left Wrist rotational motion as produced by the swivel action of the Forearm (2-K #4).

So, in The Golfing Machine®...

There are no horizontal pins.

There are no angled pins.

There are only vertical pins.

I agree need to be correct..

No Horizontal pins, I stated Horizontal Hinge Pin, 1-L is labeled Horizontal Hinge Pin...Now I am really confused, cause I went to 1-L and used the percise terms/words that are in the book.

I did note that the pin itself was perpendicular to the ground cause we had this dicussion on hinge pins and vertical before, where my preferrence is to use perpendicular cause of it normal reference of the word vertical and horizontal.

So you are telling me that my label is incorrect? If so then my use of 1-L was totally misplaced...and .... I really need help here. The label on 1-L is rather clear to me...
