21 important points?
 

Characteristics of all Mechanically and Geometrically Correct Golf Strokes


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 Clubface alignment
5 The Clubshaft lies full length on a flat. tilted plane
6 The Clubshaft always points to 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 through Impact by an On Plane force, (moving towards the Plane L:ine)
11 Clubhead Force and Motion is On Plane at right angles to the Longitudinal Centre of Gravity and varies with the speed, Mass, and Swing Radius
12 Ball speed is dependent on both before Impact and after Impact Clubhead Speed
13 The Clubhead travells Down and Out until it reaches "Low Point"
14 Divots are taken "Down and Out" not just "Down"

16 The Plane Line controls the Clubhead Line-of-Flight. Clubface alignment controls the Ball Line-of-Flight
17 The Clubface need 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 relationship of all Machine positions and motions can be described by a geometrical figure

The 21 Golf Axioms
 

Axiom: n. A self-evident or universally recognized truth.


I just love the 21 points in 1-L. And, I live on their principles every day in my teaching.

Lynn Blake Certified Instructors are required to memorize them and relate them individually to the major concepts of the Golf Stroke. This results in a greater depth of understanding and an increased ability to solve each student's unique swing challenges. They are far better teachers with this skill than without it.


:salut:

It's very interesting (and telling) that no instructor I've met can name - let alone explain - these 21 points. While this information can be overwhelming for guys like me, it is essential to move forward. Thanks so much!! Jeff P.

1-L, is for the way you look at me.
 

1 The Stationary Post (player's head) accurately returns the Clubhead through the ball (Centered Arc)
Regardless of Axis Tilt of the body, Tripod with centered eyes.

2 The Post may turn (Pivot) but does not "Sway" or "Bob"
Provides a fixed Head height.

3 There is no wobble in the Clubshaft attachment (Grip)
The Hands are clamps. Extensor Action

4 The Hinge Assembly controls Clubface alignment
The First Imperative

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

6 The Clubshaft always points to the Plane Line except when they are parallel to each other
2-F

7 The Lever Assembly is driven by exerting pressure against it
(Note: 7 thru 11 deal with the movement of the Lever Assemblies and the Second Imperative)
Pressure is on the aft side of the shaft Pressure Points 1,2,3

8 No portion of the Lever Assembly can swing forward independently
Bent Left Wrist

9 Regardless of how the Lever Assembly is driven, it moves in a circle
Around the left Shoulder

10 The Lever Assembly must be driven through Impact by an On Plane force, (moving towards the Plane L:ine)
Swingers use Centrifugal Force, Hitters use Muscular Drive of an active Right Arm.

11 Clubhead Force and Motion is On Plane at right angles to the Longitudinal Centre of Gravity and varies with the speed, Mass, and Swing Radius
Not Clubface Motion, Sweetspot, Pressure is on the aft side of the shaft.

12 Ball speed is dependent on both before Impact and after Impact Clubhead Speed
Not from effort, but a mechanical advantage. Reference 2-E

13 The Clubhead travells Down and Out until it reaches "Low Point"
14 Divots are taken "Down and Out" not just "Down"
Reference Yoda’s drawings I posted this week.

15 The Club starts Up and In after "Low Point" but the Thrust continues Down Plane during the Follow-Through
No quitting, the right elbow is still bent at Impact and Low Point and continues to Drive or be Driven until straight which is at the end of the Follow-Through (8-11), reference 6-A-4.

16 The Plane Line controls the Clubhead Line-of-Flight. Clubface alignment controls the Ball Line-of-Flight
Both must be monitored. Imperative #3 and #1.

17 The Clubface need to be square to the Line-of-Flight only at Point of Separation
Impact and Seperation are two different points and can be up to 3/4 of an inch in difference.
The Left Hand face down the Angle of Approach at Impact.

18 Changing the Plane Angle has no effect on the Plane Line
The roof can change, but the gutter remains the same.

19 Stance Line, Plane Line and Flight Line are normally parallel
“Normally” being the key word.

20 For any given Line-of-Compression (through the ball) every Machine must produce identical Impact Alignments
Impact Alignments must match the desired shot.

21 The relationship of all Machine positions and motions can be described by a geometrical figure
Everything has a geometric relationship to everything else.

OMG, what a post!

Thanks Drew!!!

Kevin

This is exactly what I was hoping for. More enlightenment. Thx.

In my opinion YODA has treated us to some of the greatest pictures ever in G.O.L.F. this week, and Drew just treated us to maybe the greatest post. Only on LBG!

Kevin

Yes, this is pure GOLD. I had a MORAD instructor - didn't discuss any of this. I had a S&T instructor - didn't discuss any of this. Can't believe what I've been missing. No wonder I couldn't build a proper foundation to my golf swing. Thanks guys!

Great post Drew !

Nice work Drew!!

Thanks Drew. I needed that. I just saved it in three spots on my computer. I can lose anything anywhere.
It truly is remarkable--all this stuff we learn here.

Drew Hits 21!
 

Great job, Drew. I went through your synthesis of every point and concur 100 percent. Thanks!

:salut:

Return of the Jedi
 

Well after all, I was trained by the best :yoda: :) ,

Your post, and avatar of one of my fav comics, made me very happy!
 

I'm actually looking forward to the winter driving range! So much to work on!

2 questions.....
 

Could someone point me to the drawings referred to about the divot in 1-L-14

and

in 1-L-16

What exactly is meant by "Clubface alignment controls the Ball Line-of-Flight"?

Does this mean the shape of the club face at separation controls the golf balls initial direction or how it curves or what?

A Picture is worth a 1,000 words
 

1-L-14 and 1-L-16 are pictured in 1-L. The 21 points explain the picture.
Reference 2-G and 2-D-0, regarding Clubface alignment control for starters.
Initial Direction at seperation unless the Venturi effect has enough time and speed to cause the vectors to scatter.

Nice one Drew , gonna copy this to my LBG file too.

I believe the original post had a slight typo in 19. Should read "Stance Line, Plane Line and Flight Line are normally parallel." I know this is a weird thing for the kid at the back of class to note.


.......Hey its recess...

You are right. I just copied something I found. It is now corrected in post #1, but I can't correct it in the other posts ...

Drew,

I'm sorry. I don't think I was clear. I was referring to this:

This is the same essentially as the trackman "stuff" . . . if there is a divot the club is traveling down AND OUT . . . period . . . so down is "swinging to the right" . . . the right of "something" . . . maybe not the correct something but to something. Lowpoint . . . ala hulu hoop in the ground.

All Better Now
 

Done!

:)

Thank you for clarifying.

Down and Out to a degree consistent to the angle of the inclined plane being employed (assuming you are on a plane). The flatter the more out , the less down the steeper the more down and the less out.

There are Angle of Attack, Arc implications associated with plane angles and shifts. So though the actual plane angle being employed may be said to be irrelevant to the measurement of ball reaction its still part of the overall geometry and anything but irrelevant to a golfer, especially one trying to aim his circular clubhead orbit in some manner....unless he choses to trace circles with his clubhead but then he'd need to change that circle for each club , for each ball position, for each release point, for each plane shift etc. Far easier to just use the straight plane line. Or the alternate method the Aiming Point.
