[12 piece bucket]

Birdie,

-- Bucket, run your search and tell us how many times -- and deliberately chose it over the 'point-between-the-shoulders' alternative (mentioned once and as just that, a deliberately rejected alternative).

1-L MACHINE CONCEPT 1. The Stationary Post (player’s head) accurately returns the Clubhead through the ball (Centered Arc).

2-0 A. The Three Basic Essentials are:
1. A stationary Head

2-H The spine, between the shoulders, is the center of the Shoulder Turn only, not of the Left Arm, except by specific extension of the Swing Radius. Because, Swinging from the Wrists, the Left Shoulder, the Right Elbow, the Waist or the Feet, show it to have just to many exceptions. Though the “Head” Pivot Center is recommended, it is not at all mandatory.

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 Stationary Head and the other in the ground precisely between the Feet, with no regard for Body Location or Position at any time. These lines may be a duplication. If found eliminate one of them.

More to come . . . gotta go eat!
