Hinge Action not in Zone #3
 

Why has Hinge Action gone from Zone #3 (Hands Lane) to Zone #2 (Arms Lane)?

Surely Hinge Action has everything to do with Ball Control and hence should be in Zone #3.

What the heck was Homer on when he made these changes? :think:

No, I disagree. Its rightful place is in zone 2. The travel between each Hinge action is different (rhythm) has everything to do with the clubhead and the straightening right arm for the procedure at hand.... hence clubhead control.

Go get 'em Mathew!
 

I agree.

Change is tough for some, but I know where he was coming from on this.

Makes sense to me.

Gathering evidence
 

Thanks Mathew for the reply, however I find the reason you have given is inadequate for me. I hope those who agree are not agreeing just because Homer made the changes, ipso facto, it must be correct. If it is so obvious that Hinge Action belongs to Zone #2, then why did Homer put it in Zone #3 in the 6th Edition? Was it just a careless mistake? I bet you it wasn't. Have the reasons that got Hinge Action in Zone #3 become invalid or superseded by other reasons? This is what I want to know.

I get the feeling that if Hinge Action were to be in Zone #2 in the 6th Edition, but moved to Zone #3 in the 7th Edition, everyone will be saying that it belongs to Zone #3 and will give all the possible reasons to validate the change.

This is such an exciting topic and can be explored from so many different angles. Lets start with the common sense approach. How many times have you heard about Hinge Action being used to control the Clubhead? Compare this to the number of times Hinge Action being associated with Clubface control. I can tell you for sure the latter far outweighs the former by a lot. Let me give you a few examples:

There are many more so I will not bore you with more quotes.

But lets here what Homer Kelly had to say in the 7th Edition about Hinge Actions:

""Hinge Actions" describe and control the manipulation of the Hands through the Impact Interval. This Hand manipulation in turn controls the Clubface MOTIONS." (7-10)
Sounds like Zone #3 to me.

But like Mathew said, each Hinge Action has a different Rhythm and hence difference Clubhead Travel. But that's only because of Accumulator #3. If we zero out Accumulator #3 all three Hinge Actions will have identical Clubhead Travel. Accumulator #3 is about Power and Force not Purpose or Direction and hence belongs to Zone #2 (see 9-0).

Having said all this, there are things Homer has added in the 7th Edition that needs to be examined. For example, the 6th paragraph of 7-10:

“The Left Shoulder, the Right Elbow and/or the Wrists supply the Clubhead Hinging because it does not require more control than that of Swivel type Hinging; However, The Flat Left Wrist supplies the precision Hinge Motion Control required for the Clubface. The Flat Left Wrist rides The Lever Assemblies and its relationship is constant. But also independent by reason of its required relationship to the Basic Planes per 2-G. Per sketch 1-L, Hinge Action is inseparable from Angular Motion and so it can only go aright or awry but not away."


I have more to say lets have more people chiming in...

Zone #2 Hinge Action
 

In my opinion, the quote above is the rationale -- the only rationale -- behind Hinge Action's new home in Zone #2.

In other words, Hinge Action is generated automatically by the physics of Angular Motion (2-K) -- Horizontal Hinge Action by the Throw-Out of Centrifugal Force and Angled Hinge Action by the Drive-Out of Muscular Thrust. Vertical Hinge Action is the byproduct of neither and hence is always a deliberate, mechanical manipulation.

Thus, Hinge Action executed by the Flat Left Wrist provides only a veneer control that "individualizes" Angular Motion's Clubhead Control into the three possible motions of the Clubface (Close only, Layback only and simultaneous Close and Layback). Which, also in my opinion, is why Hinge Action was a Zone #3 Component in the prior six editions: Zone #3 is all about "Clubface Control" -- "Accuracy" and "Direction" -- and is "mostly 'finesse' control" (9-2). Zone #2 is "Clubhead Control (Power)" and its "Power Components" (9-2).

So, this 'sea change' was a bold step, one that impacted many areas of the book. Its 'as is' inclusion in the seventh edition has now introduced many inconsistencies throughout the text that could have been -- and should have been -- resolved prior to publication. This is not 'Monday morning quarterbacking': It was one of the three primary concerns I voiced last winter http://www.lynnblakegolf.com/forum/s...1962#post21962. In addition to the integrating actions mentioned in that post, considerable conceptual and textual changes also are required in Chapter Nine (The Three Zones).

Hinge Action
 

A lot of good thoughts here:
Leo, absolutely a big change- and nice job questioning the reasons behind it- it deserves that kind of questioning.

I also think that Lynn was correct in explaining why the change was made- and I do think that Homer was telling you the rationale for changing it as quoted.

You might think of it like this- as noted in the 6th edition 2-G. The Geometry of hinging is clubface control- The Physics of Hinging is that Hinge Action is the result of the turning torso or orbiting arms. So he's given Physics the nod over the Geometry in regards to it's categorization in Zone#2 as opposed to the 6th edition in Zone #3. Why?

It's been 24 years since I learned of the coming change of Hinge Action from Zone#3 to #2. And I had the feeling of - "What - how could he do that!!!"- because it does really create a mental shuffle for you and everything that you've learned. I asked "Why would he do that?" And the answer that I got was "You see- everybody thinks that hinge action is something you do with your hands- and IT'S NOT!" Hence, the categorization change to move it into a category that better categorizes the component in relation to the procedural nature of the movement.

As far as the integration of concepts in the book for clarity- that's been a problem from day one. And as Lynn points out - continues to be a major flaw that doesn't help anyone. Woulda, Coulda, Shoulda in the 7th edition, but there was no way- that was going to be Mr. Kelley's 7th edition and no one elses. Those changes are needed but would have to be in the 8th edition- and if the 7th took about 24 years to publish then I guess the 8th could take over 100 years to publish.

Let's hope not Mike. :rolleyes:

Truly Understanding Hinge Action
 

Mike O's quote above is one of the most important statements you will ever read concerning the essential nature of Hinge Action. It demands a Yoda Hinge Action -- Part III video.

Coming soon to a computer screen near you!

No, I did not elaborate, I just didn't want to write a thesis on the matter. Where you got the 'I'm just agreeing with Homer Kelley because he made the changes' like im a Homer drone with no brain...I do not know. Anyways, it is obvious that there are issues with hinge action on both clubhead control (angular motion) and the clubface control. Every procedure drives the primary lever assembly by creating a pressure against it which will naturally create a hinge action. Pivot driving the left arm - dual horizontal, Right forearm driving the left arm - angled... The difference right arm participation.... arms lane....

Its not to say that it doesn't belong in zone 3 either because the clubface motion through the ball is important...but there is a case for it being in zone 2. It is a grey area that Homer Kelley must of weighed up and this time chosen to be placed in zone 2.

Bring It Green Thing!
 

Lynn, somehow someway I get held responsible for your next adventure- But WE love video- So bring it on! :)
