The Machine Concept (1-L) - Shall we review?
 

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

2. The Post may turn (Pivot) but does not “sway” or “bob”.

3. There is no wobble in the Clubshaft attachment (Grip).

4.The Hinge Assembly controls the Clubface alignment.

5. The Clubshaft lies full length on a flat, tilted plane.

6. The Clubshaft always points at the Plane Line except when they are parallel to each other.

7. The Lever Assembly is driven by exerting pressure against it.

8. No portion of the Lever Assembly can swing forward independently.

9. Regardless of how the Lever Assembly is driven, it moves in a circle.

10. The Lever Assembly must be driven though Impact by an On Plane force (moving toward the Plane Line).

11. Clubhead Force and Motion is On Plane at right angles to the longitudinal Center of Gravity and varies with the Speed, Mass and Swing Radius.

12. Ball Speed is dependent of both before Impact and after Impact Clubhead Speed.

13. The Clubhead travels Down-and-Out until it reaches its “Low Point”.

14. Divots are taken “Down-and-Out” – not just “Down”.

15. The Club starts up-and-in after “Low Point” but the thrust continues Down Plane during the Follow-Through.

16. The Plane Line controls the Clubhead Line-Of-Flight. Clubface alignment controls the Ball Line-Of-Flight.

17. The Clubface needs to be square to the Line-Of-Flight only at Point of Separation.

18. Changing the Plane Angle has no effect on the Plane Line.

19. Stance Line, Plane Line and Flight Line are normally parallel.

20. For any given Line Of Compression (through the ball) every Machine must produce identical Impact alignments.

21. The relations of all Machine positions and motions can be described by a geometric figure.

1-L-10

Is at the top of my list.

These are the 20 things that must happen for a Geometrically Correct Stroke.

"execute like a machine"
 

because, the "machine" also cares nothing about the:

machine itself
club
ball
ball flight, carry and distance
target
hazards
results
mistakes
scores
partners
ego
pressure
confidence
prize
title

Yoda told me, in order for me to keep my Jedi status ;), I had to carry 1-L with me in my pocket and memorize the list. My poor little list is so worn and tattered. I think next time I'll have it laminated.

A bag tag with 1-L and 2-0 on it would help many, many people.


Perhaps someday someone will - 'Get it' :D

Hmm . . . Naughty naughty! Do you need a time-out young man?

A bag tag, now that is a great idea!!!!

I am a little foggy about 1-L-15. Can anyone explain how the Thrust continues downplane once the club passes Low Point and starts moving up and in?:???:

Clearing the Fog On 1-L-15.
 

The Right Elbow is still bent at Low Point. Consequently, the Right Forearm continues to Drive (Muscularly / Hitting) or be Driven (Centrifugally / Swinging) toward the Plane Line until it is fully straight.

For the record, this is one of my favorite 1-L axioms!

johngolf33,

For the thrust to go anywhere but downplane is to Steer per 3-F-7-A.

Imagine setting a huge wheel on an inclined plane. To start this wheel spinning, we can both pull the rim or push the spoke in a direction toward the plane line, i.e. downplane. You never push or pull it towards the target.

You are saying poor ball strikers intentions are wrong and that it is a Downswing NOT an Alongswing so, for clarification, could we paraphrase 1-L-15 by saying "The Club starts up and in after “Low Point” but the intent continues Down Plane during the Follow Through."?
