The Sign says 'Open for Business'
 

Where in the world is EdZ? Is it Winter Hibernation? This is the most important Room in “The Lesson Tee”. Let’s start swingin the dowels. C’mon, lets review the drills, innovate, work on the hard stuff. The Snow is about to melt. I feel like I just walked into a Silent Movie.

We need a Topic. Something to Really chew on, that doesn't end in Breast, Thigh, Leg or Wing.:) Let's show the Hitters we really got something going on in here.

Homer did say you could swing in your sleep!

Endless Belt
 

How about some "endless belt" discussion? I'm sure it's been hashed out in some older threads, but for those too lazy to do a search, maybe we get a little 2008 discussion going on it.

I have a tendency to want to accelerate my hands all the way through impact..... that's a no-no isn't it?

CG

That's a great subject. The 7th edition includes some additional info on the matter.

Lead us off.

Eb
 

OK... my 7th edition is not here so I don't have any of the new info in front of me. But...... I tend to use what I believe is a fairly "small pulley" (bordering on a snap release). My understanding of the EB is that my hands are taking a straight line path into release at which point the linear velocity of my hands is translated into angular velocity as CF throwout begins. That angular velocity is faster than the linear by an amount that's related to the pulley "size".

When I want to really "stand on one" I almost always revert to trying to keep my hands accelerating into impact which (I believe) disturbs CF and the EB action. If my understanding is correct what I should be doing when I want to hit one further than "normal" is to either decrease my pulley size and/or find a way to get my hand speed up in the period between start-down and release. I should not try to keep the hands accelerating past the release stage.

Sound correct?

That is better!
 

I can reference 2-k # 6, but I would prefer to tell you what the endless belt did for me!


Endless belt effect of # 3 Acc. ---- straight line delivery path --- more upright plane (turned shoulder plane) --- 3 dimensional impact ---- more up and down than I thought sane --- Compression!

Understanding the Endless Belt Effect opened my eyes to the sequence of learning represented above! It represented the dynamic concept/image that I needed. I actually hit balls thinking "slow hands...slow hands" I think a key in competive golf is to be deliberate without a hint of steering. Firing accumulators in sequence helps...but know that you do not have to have flash hand speed (unless you want take em' around the mulberry bush) it sucks the anticipatory stress out of the process. It allows us to think process...procedure...and consequently stay in the present. Funny thing is that my lack of play in recent years led me up to this point. For this reason and that reason I have not played much, but I did work on my game in my armchair. I am chomping at the bit...practically foaming at the mouth!

I have "reduced" my TGM bag o' tricks to the proper understanding of Homer's "Big Ideas." It has taken over a year! I know that there is a deeper level of understanding for teaching purposes, but I am now able to execute physically what I understand conceptually...what a rush!

One day I may be able to reference the book in an expert manner. I can however find the "Biggies" as fast as a seminary student can find John 3:16!

Obviously the Endless Belt Effect is a "Biggie" I think I ranked it second to the Flying Wedges in light switch ideas for me...Geometry of the Circle was helpful...the elusive Extensor action very instructive...hinge action is cheating....law of the flail brought me closer to my agrarian roots...bent and vertical right wrist made me respect all of the spear throwers of antiquity...on and on!

I am aiming for my 100th post before January is done!

That is how I understand it Comet! Keep the belt going and watch that puppy take the corner on two wheels! :golf:

96!
 

And then Yoda turned to YodasLuke and said...

"Knowing that this Effect is in operation will keep the player from attempting to 'speed up' the Hands during Release, an ill-advised and almost always ill-fated attempt to increase Clubhead Speed through Impact. Per 6-P-0, it is only necessary to keep the Handspeed 'strong, consistent and Rhythmic.' In other words, Sustain the Lag!"

Doesn't get much clearer than that!

Amen! :salut:

I think Mr Kelly forgot to add-"but when you can,you will give hitters nightmares":laughing9

SUSTAIN..... not ADD
 

After braving the elements this evening and putting the old rainsuit and Underarmour on I ventured to a local range to work on some "hitting" chip/pitch shots in prep for a 2-day event coming up this weekend. I brought only my wedges, so I wasn't tempted to work on full swing drivers.

After an hour or so I had worked thru my bucket and was heading to the car when I saw 20 or so balls sitting there (imagine that... 38 degrees, misting, and someone had left some rangeballs un-hit!!!!!). I decided to use some half-swings and really work on simply maintaining my handspeed from release to follow-through (no acceleration allowed). I think it's even tougher on half swings to do this, but I thought what the hey.... these balls were free anyway. Well.... it was amazing just how solid these SW shots flew, from marginal lies no less. The EB discussions from today sort of resonated in the back of my head and it struck me that as many times as I've heard "Sustain the Lag" in terms of TGM over the last 3 or 4 years I never really thought about what it meant.

Sustain doesn't mean to increase. It means to support and maintain. One would think that if you have lag then adding to it would be a good thing. At least that was probably bouncing around in my head. After doing a search here on "sustain the lag", some really good posts came up..... not suprisingly led by Mr. 12-Piece. Very clarifying.

Could be one of those ah-ha moments.... we'll see.

This place really IS good!!!!

hmmmmm . . . one grown man is laughing out loud at a computer screen (probably rocking as well) while his wife is calling him "nuts."

Another grown man is coming back every single day posting dissertations on minutia of how accumulator numbers came to be while also saying "Oh yeah I'm done with internet forums now . . . " mmmmmm hmmmmm sure you are . . .

And another grown man is employing a FAKE british accent to take advantage of unsuspecting vulnerable obese women.

Another grown man physically assaults a bell hop because the complimentary continental breakfast "don't have no biscuits or no gravy!!!!!"

Another grown man who happens to be a certain tour caddy was arrested for shooting yardages with his range finder nekkid in the dark at 4 am on a putt putt course in Houston.

And now you another GROWN MAN are stealing range balls in subfreezing weather IN THE RAIN no less . . .

Yeah this place is GREAT!!!! You people are freakin' CRAAAAAAZYYYYYYY!!!! With a capital crazy!!!!

Yeah I know y'all are saying "Who are you to say that!!!" Pot calling kettle . .

But the difference is . . .

I KNOW I'M A FOOL.

Sergio Pulley

Since I have absolutely no clue about including pictures, the geometry added to Sergios Swing pics are in the attached thumbnail. The difficulty I had in attaching this picture is somewhere between fixing a leaky faucet and rubbing two sticks together to start a fire.

If you start at the first picture of the sequence, notice I outlined Sergios Hand Locations on his Backstroke and Downstroke. I had to extrapolate one to finish the pulley.

Anyway, look at the Centers of the Pulleys.

The Pulleys are the same size. If you review Yoda next to Hogan in "The Gallery" their Heads are much more centered over the ball which results in better Straight Line Delivery Path and their hands enter the Pulley more sharply.

Sergio pulleys are not as small as Hogans. Keep in mind that for each inch the Pulley decreases in diameter, you have an exponential increase in Clubhead Speed and that means Lower Effort Output for equal Clubhead speeds. And that's not all. Hogan enters the pulley slightly closer to the pulleys Horizontal Centerline so has more delay in Release. So, two properties of the Pulley are Size and Entrance Location. The Size of the Pulley is pretty much fixed. Your Body Size, Shape, Height and Arm Length pretty much determine all of that.

Also, please notice that Impact Hand Location is not the Lowest Hand Location during the Swing (Ball Location) but that the Center of the Lower Pulley is over the Ball. That means Phenomenal CF. Almost zero Clubhead impact deceleration. His Primary Lever becomes a steel rod. Awesome Clubhead Mass. You can write a book on that Issue alone (oh? HK already did). Consider that the next time you want to play the ball back in your stance. The father back in your stance you position the ball, the less CF you generate for the same hand speed.

Lastly; Do you see very much Delayed Release? I don't. It only looks like Delay because his head is so far behind the Ball at Impact.

Lastly Lastly; The centers of Sergios pulleys align with the impact hand location. That has nothing to do with anything. I just thought it made a really nice looking diagram. The Big white Circle represents the outline of his clubhead path and does not represent low-point. Close but no Cigar.

Remember the endless belt is a concept to illustrate the differences in the hands moving in a wide circular fashion versus moving in a sharp more linear fashion. As your pictures illustrate the hands don't actually move in a straight line.

Now as for Sergio . . . go to Youtube and watch some of his swings. He stays right on top of the ball. There's not a lot of moving around in his motion of his head relative to a lot of the pros out there. Go to Youtube and watch some swing visions . . . The other thing you'll notice about this motion is there is relatively little axis tilt in comparison to some of the other dudes out there . . . Zach for example. If Sergio had tons of Axis tilt ala Ben Doyle you'd never have heard of him.

We've been here before but watch his swing and look how high his club is off the ground as the hands get in the area of the right and left thigh. This swing is STEEP. Look at Zach's motion that is SWEEPY. Watch the swings and watch the angle of attacks. Sergio has a big shift to a flatter plane but the swing is still STEEP.

Do some comparison work and see what you can figure out about how the motions are different and how the comparitively work.

:laughing9 I beg to differ. The Endless Belt simply demonstrates that a 46” Secondary Lever attached to a smaller pulley will have greater Clubhead Velocity than a 46” Lever attached to a Larger Pulley but that the end of each Secondary Lever ( and this is the important point of the concept ) travels at the same RPM as the Hand it is attached to, so the Concept blends nicely with the Hinge Concept (with which I also agree) and Clubhead Speed and Hand Speed are related but not necessarily cause and effect. Shorter People will have a smaller pulley. Tall people have a larger pulley. You do not get a smaller pulley if you swing shorter clubs. That's why a Driver has Higher Clubhead Speed than a Wedge. That is also why an apparently short person like Hogan Could Hit the Ball as far as a taller person. If you outline the path of the hands for one foot before and one foot after impact of every golfer in the world, then you'll see this relationship. I'm giving you Jewels here.

I’m not beating on Sergio. If you want different results then put up a different sequence. I can't help it if his Stationary Head looks like a Bobber in a Large-mouth Bass fishing competition. I’m sure that he wasn’t posing for this swing (oops, maybe he was) and I’m sure that it was the only sequence of photos taken of him (oops, maybe not). I’m most sure that Sergio has better Swings. As soon as I find one, I’ll use-em.

However, it’s my understanding that this sequence of him Hangs above the Alter you built for him next to your BBQ Grille. So I thought you would enjoy seeing it again. :laughing9

Whadayamean? Sergio is 5 feet off the ground. How steep can it really be? (That's not a dig on shorter people, please forgive me)

Comparison work? Who? Me? The Illustration Graphics are merely representing a concept which is unfamiliar to you. The Endless Belt Effect. Comparisons would only illustrated differences among Golfers whereas the Sergio Illustration illustrates the samenesses of the mechanics of the concept.

As the President of the Sergio Fan Club, you can tell him that if he has a problem with me, then sign in to LBG.com and comment. :laughing9

OK bossman . . . I don't have the hots for Sergio. I'm just illustrating two ends of the spectrum. PLEASE go to Youtube and watch the Zach Johnson sequence versus the Sergio sequence. Heck if you want to see the same comparison with a different name watch Boo vs. Zach. Look at the heights of the clubhead off the ground at that point in the swing comparitively.

Stop the video when their hands get right in the middle of the right thigh . . . tell me what you see. AND Boo doesn't have the "thrownaway" look that you so despise either.

Look at all three . . . . .

I'll put somemore sequences up for you . . . I couldn't find one of Zach.

It doesn't have two do with how tall he is . . . it's how much the Lever is shortened by the amount of wrist cock.

I'll find you some pics . . .

I have some video of one Lynnard Blake . . . saying . . . "I COME DOWN ON IT STEEP."

Check the video dude . . . Sergio stays right on top of it . . . Because he HAS TO . . .

SwingPlex of Sergio
 

Have you two guys seen Sergio's down the line Driver swing on the SwingPlex feature at the pgatour website. It is very cool...it would be interesting to see your comments....it shows incredible extensor action and his flattening of his swing plane on the downswing.

Alright dude . . . here's what you need to watch a side by side . . .

You can skip to about the 8 minute mark and then you'll see the difference for yourself what I'm talking about . . .

High clubhead vs. sweepy clubhead . . . AND the dude is hitting a shot outta the rough . . .

What Sport are you talking about?????

2-M-2 POWER REGULATION Clubhead Lag Pressure Point pressure (6-C) is the Power Regulator. It meters out Power by sensing Clubhead Acceleration Rate and Direction. That is:
To vary the Effective Clubhead Mass, vary
1. The Acceleration Rate (Lag Pressure 7-11)
2. The Swing Radius (length of the Primary Lever Assembly 6-B-0)
To vary Clubhead Speed, vary
3. Acceleration Time (Length of the Stroke 10-21)
4. The Release Interval (Centrifugal Reaction 6-N-0)
So it is optional to use any one or any combination of the four alternatives. Also study 12-0 in this connection.

You want to add #5 - Decrease your Pulley Size.

Homer only tells you how you can COMPENSATE FOR YOUR ONE SIZE PULLEY by Raising or Lowering the Hand #3 Accumulator TRAVEL. He does not tell you that you can physically change the size of your pulley. Greater #3 Accumulator Angle, has greater Travel and Should be compensated by Higher Handspeed because it will take longer for the Clubhead to get around the Pulley. Conversely, If you reduce the #3 Accumulator Angle you'll have less Travel so you won't need as much Handspeed.

In other words, he is telling those with slower hand speed to reduce the #3 Accumulator Angle. Or, if you're a Hitter, just eat more red meat.

First, Both Swings are awesome. Thank you for sharing them.

Second, The commentator shouldn't be talking about something he utterly knows nothing about.

Third, What you think you are seeing is not what they are doing.

Tiger's Hip Center is 2" ahead of his ball location and his Head is dead on the Ball at impact.
Zach's Hip center is dead on the Ball at Impact Location and his head is 2" behind the Ball.
Though Zach moved to his left side perfectly, Tiger moves slightly more.

Zach has a very small #3 Accumulator angle. Tiger's is greater. Tiger can do that because he has higher hand speed. It looks like zach is sweeping compared to Tiger. But, he's not. For you, it's just not having enough information availble to analyze the comparison. Now you do. However, you're ten times more knowlegable than that commentator.

They both have a Straight-Line Delivery Path. Tiger's is slightly more vertical. Zach has textbook form. So does Tiger. TGM Textbook (in this video anyway).

Daryl . . . New Thread Started . . . Class is in session . . . Bring your note book #2 pencil . . . and no putting boogers under the desk!!!

Hibernation would be nice... that would mean I'd be getting some sleep!

The little guy is keeping me more busy than I would have imagined, but soon I suspect he will be sleeping for more than a few hours at a stretch, or at least that is what my wife and I keep being told!

As for the endless belt, you can keep up the lag pressure, all the way 'down' plane - focus on PP#2 and a sequenced release - keeping in mind that it is the pivot that 'throws out'.

Accumulators 2 & 3
 

Daryl,

You make it sound like #3 works like #2. Is that right? Aren't they always talking about pulley size and hand speed? Pulley is #2, right? And those discussions are always about hitting the ball the same distance----bigger pulley requires faster handspeed to acheive same distance. How does hand speed affect ability to transfer power through #3? If I have a big #3, do I have to swing my arms slow to get it around the corner? Or can I just rotate my left arm faster? Really confusing. Let me know.

Hip Center
 

What is the hip center? Is it the seam on the pants? How does it
relate to the center of body mass talked about in the "final missing
piece"? Does the edge of the hip go past the ball to get the
center of mass next to the left leg? Or does the the 45 degree
backward hip turn get the hips even with the ball? Would be nice
for V.J. to comment on these questions.
