Stationary Head - To be or not to be
 

There has been an additional text to the second paragraph on
2-H in the 7th edition.

"The important thing is that the true Swing Center for ALL COMPONENTS is around a Hinge Pin with one end at the top of the Stationay Head and the other in the ground, precisely between the feet, with no regard for Body Location or Position at any time"

How do you read this? What does it mean for you?
What is your interpritation(?) of it?

It Is What It Is
 

It means...

1. Set your head where you want it to be at Impact; then...

2. Leave it there until after the Follow-Through (Both Arms Straight position) and into the Finish. In the interim, allow your Body (Hips and Shoulders) to move as necessary to Load, Deliver and support the On Plane Club.

So.....
 

Although he writes that the stationary head is NOT mandatory,
this statement and your description makes it mandatory!

Could this not be the end of the debate?

The Real Debate
 

Amen Corner,

If you moved your head by x inches in any direction, are you able to move it back x inches?

All the time?

Per 1-L-1, "The Stationary Post (player's head) accurately returns the Clubhead through the ball (Centered Arc)"

With that, the Real Debate is...why wouldn't anyone want a centered arc?

I don't know where I got this, probably a little from a lot of places.

Stationary Head is stationary head, but that doesn't mean that it may not move. It is just not suppose to move on its own, initiate motion, etc. It can move by pivot motion IMO.

One must remember that golfers body must be taken into account, not all bodies have the flexibility to make shoulder turns and/or hip rotation and not cause other parts of the body to follow.

With a machine, the top point would be fixed unless an unbalance situation would arise. Then the machine would be redesigned to establish a proper balance for the motion to prevent the top from moving.

With the golfer's body, flexibility many limit pivot movement that can be performed prior to head movement. There must be a limit to the amount of acceptable movement, rule of thumb is it should not exceed movement past the right knee. Movement up and down or side to side on its own is unacceptable. If the movement of the head by the pivot is such that the to maintain body balance by other components, a problem is at hand IMO.

Clarification
 

Comdpa,

Let there be no mistake, I do understand the concept of Pivot Center.

The reason of my thread is that there has to be a reason why it is put in the 7th edition, and I have talked to other AI´s about the subject, and I have received different interpretations on this sentence.

You can read it as the hinge pin should be vertical during the hole swing or that the pin can tilt to one side or the other as long as the end in the ground do not move from it´s position, which is precisely between the feet. The mental picture I have in front of me is like a metronome.

How do you interpret it?

See 7-12 . . . I think that should clear up any interpretation issues. The title of the section is Swing Center TRIPOD. The head does't move, but what is UNDERNEATH it may. And in 1-L #1 it says STATIONARY Post (player's head). The post is IMAGINARY . . . It ain't the spine. It is a line drawn up between the feets and up through the mellon. Also see Axis Tilt in the Glossary . . .

Mechanical - To change directions, the helicopter pilot alters the plane of the rotating blades by tilting their axis in the new direction.

Golf - To change the plane of the Shoulder Turn without moving the Head, the golfer must tilt the Shoulder Axis by moving the Hips.

Further Clarification
 

Are you not talking about a stationary head?

Translation problems
 

Compda,

Sorry for the poor clarification, I will blame it on that english is my third language.

The point I want to make is that on page 29 under 2-H, regarding the Hinge Pin through the stationary head down to a point right between the feet, Mr Kelley suddenly In My Translation, makes the stationary head mandatory. Which could end the debate that our humble host has with the host of another TGM-site!

Or is my translation faulty?

Nailed
 

I think you just hit the nail on the head...:)
