If you watch a girl slowly twirl a baton you can see the ends going round and round. If she twirls fast enough, then the ends blur and she can make the baton look like a spinning disk. If she has a 42” thin rope with a weight at each end and spins it slowly over her head, then the weighted ends would droop and it would appear as though she is spinning a cone shaped object. If she spins the rope very fast, centrifugal force will pull the weights outward and the rope will straighten and it will look like it did when she twirled the baton.
The faster she twirls, the greater the centrifugal force and the tighter and straighter the rope. The two weighted ends are moving directly away from each other so the rope is in a straight line. If the ends didn’t pull directly opposite each other, then the rope would be bent in some way.
If she spins the rope with weighted ends, and hits your car door with one of the ends, the weighted end will dent your car door. Centrifugal Force did not cause the dent. The velocity of the weight caused the dent.
The Hitter does not use Centrifugal Force. He applies muscular force to the Primary Lever through the #1 Pressure Point by the #1 Accumulator and Uncocks the Left Wrist using the Same Muscular effort down the same path. The primary Lever is the Left Arm connected to the Clubshaft with a Flat Left Wrist. The Left Arm Flying Wedge. The endless belt effect is how the velocity at the end of the secondary lever increases without increasing its RPM. TGM Golfers will agree that the hitter does not use CF. And that’s correct. They are also aware of two Levers. One Primary and one Secondary.
The Swinger does not load the Primary Lever. Why? Because he hasn’t created one. Centrifugal Force creates the Primary Lever. It Pulls the Clubshaft in line with the Left Arm so together, they become one long stiff solid Primary Lever beginning at the moment just before Impact. Then the Hinge (one of three) guides the Primary Lever through Impact.
Every choice of component variation that a Swinger uses must set the stage and make it possible for the Left Arm and Clubshaft to be assembled into a Primary Lever by Centrifugal Force. That means that the Left Arm and Clubshaft need to be carried in a specific way with specific alignments down to the Release Zone so that when Centrifugal Force pulls on the clubhead it will create a straight and stiff Lever.
So if the Clubhead is going one way and the Left Arm another, then Centrifugal Force will yank them into alignment but it will be too late. The ball will already be gone.
It's just a thought. I'm prepared to be corrected.
Very good post, however I couldn't help but think I'm gonna need pics, lots and lots of pics of pretty girls (and batons if you have to) to help really drive the message home.
He is talking to “Hitters” and he is telling them that Extensor Action will create their Primary Lever.
“...and just moving from “Bent Left Wrist” to “Flat Left Wrist” during-and as-the Loading Action are very effective for short shot procedures (10-19-0).” I think HK is saying: to go from the Bent Left Wrist to Flat Left Wrist will at the same time form and Load the Primary Lever. He is not suggesting that Hitters start with a bent Left Wrist, only that going from Bent to Flat creates it. Left arm and Clubshaft in-line with a Flat Left Wrist is the Primary Lever.
Then in 10-19-0, “…Drive the one, Drag the other…into Release” I’ve always missed the "into release" part of what HK is saying in this sentence. Three things happen after “into Release”. The Left Wrist begins to Uncock, the right Elbow begins to Straighten and the Clubhead is Accelerating. In the third paragraph, you can sum up all of it by saying that Extensor Action in very short Shots will create the Primary Lever for both Hitters and Swingers and may be used as a substitute for their normal Patterns. When HK says: “Then use a normal Flat Left Wrist Downstroke per Pattern for both procedures-…” he isn’t instructing you on how to get to Impact, it’s a description of the Type of impact; a Flat Left Wrist Impact (Primary Lever) for both Hitters and Swingers.
So Extensor Action for Hitters does what CF does for Swingers. It helps create the Primary Lever. But, I swing, and I use Extensor Action. I didn't before last year, but now I wouldn't swing a club without it. So? Maybe I'm just confused.
Let me sum up everything I’ve said about CF, the Primary Lever and Sequenced Releases. In a nutshell.
At the heart of TGM is the Primary Lever. Maybe not the Heart but certainly one of the heart valves. Without it, you’ll go through impact with a Bent Left Wrist and it’s hopeless. You only have a Primary Lever when you have a Flat Left Wrist, and Straight Left Arm in-line with the Clubshaft. The acid test for the Primary Lever, is the Left Arm Flying Wedge. All Hinging types need a Primary Lever. The Lever is Hinged through impact, and the Length of the Lever, if your Pivot is good (Pivot Lag), can be 12 feet long.
In Hitting Procedure, the Golfer creates the Primary Lever geometry at Startup and uses Extensor Action to unify it (which keeps the Flying Wedge, proof of the Primary Lever) and during Release he uses muscular effort to Drive the Levers through Impact.
The Swinger must rely on CF to create the Lever and bring about the rigid unity between Left Arm Wrist and Clubshaft during Release. If the Swinger Chooses a Simultaneous Release, then use 10-2-D Grip and create the Primary Lever just like in the Hitting Procedure. He’ll lose some of the advantages of a Sequenced Release, but he will have a simplified procedure.
Daryl, what are the advantages of a sequenced release then? what dos the simultaneous release for a swinger lose?
10-2-D (please read 2-P) explains all of the advantages of Swingers with Simultaneous Release. (10-2-D tipoff that HK meant it for a Simultaeous Release is when he said that the Right Hand motion is like a Paddlewheel)
The difference between a Swinger using the above procedure vs. Sequenced Release is three-fold. The Advantages are outlined below. All from the Book.
First, The Throwout Action of CF and it’s pull on the Clubs Center of Gravity will automatically square the clubface for straightaway shots. That’s cool. Easy. Forgiving and dependable.
Second, and even more inherent, and even more important, is that the Lever and Hinging System is not Timing Dependent. A swinger using true Simultaneous Release will have to time the correct amount of Uncocking and maximum force to the Ball Posistion. Sequenced Release and Horz. Hinge is Not timing dependent.
Third, Clubhead Throwaway. CF with Simultaneous Release has a lot of Throwaway Tendencies. The Wrists have to Start and Keep Uncocking all of the way through and past Impact. It’s therefore a “Controlled Throwaway Swing”.
The Swinger using Sequenced Release and Horizontal Hinging will, if you look at any of Yodas Finish Swivel videos, will have the Left Wrist Arched at full arm extension, well after impact, and almost as high off the ground as his Left Shoulder and the Clubshaft is still pointing at the base line of the Inclind Plane - ---- NO THROWAWAY in other words - the primary lever was hinged through impact.
