Endless Belt
 

I am starting to grasp the Endless Belt per 2-K.....is there a better video that demonstrates that affect than this guy's swing. I believe Mike is a MORAD student.

I also see a lot of 2-k in Yodas Luke swing, no forced acceleration.

I think for the first time last night I got this affect, it felt like the slower, deliberate and more constant the hands move the heavier the hit and the more the release was delayed....with no lose in power but more accuracy.

As I understand it:
that clip may contain "endless belt" but it can not be seen in the clip.
I think a clip from behind the golfer so that U can see the plane and the left arm pointing below plane is a view of endless belt.
As I understand, the "belt" is the club moving AROUND the left arm and only exists , to the amount, that the left wrist is cocked.
Hold the club in a normal left grip, wuth a LEVEL wrist. Swing one armed back and forth and see the club FLAIL outside the left arm.
Since the flail is dependent some cocking remaining in the left wrist I see how the coordination between #2 an#3 is critical. That may be taking it to far for this question. LOOK at a behind, plane angle swing and you will see the answer.

On the other hand, Mike is always a great study of 6-M-1.

I am very much a novice in this stuff and I am sure you are right....I just like how it looks like his hands are running at a constant speed in a straight line yet when they clubhead turns that wheel it looks like it accelerates. I bet this guy hits it a ton yet it looks like he is not forcing anything.

IMO, there's 2 parts to Endless Belt Effect.

1. The hand speed in the downswing should remain at a constant rate. I'll make up some numbers, but if the hands are moving at 50 mph at impact, then they should be moving at 50 mph in the start down. Constant rate of speed. You don't want a jerky hand movement.

As the hand speed is constant, the clubhead speed up. So if the clubhead speed is 100 mph at impact, then it could be at 75 mph in the startdown then say 90 mph at the halfway down point...accelerating into impact.

Again, the numbers that I'm using are made up, but trying to illustrate the point.

2. The size of a golfer's 'pulley' plays a factor in *how* they generate clubhead speed.

A smaller pulley is something more along the lines of a 'snap release.' A larger pulley is something more along the lines of a 'full sweep release.'

Johnny Miller had more of a full sweep release and Lee Trevino had more of a snap release. The same with straight line delivery (small pulley) vs. circular delivery path (large pulley).

Let's say that both guys had a driver clubhead speed of 110 mph. Since Miller has a larger pulley than Trevino, that means that Miller must have faster hand speed than Trevino to obtain the same clubhead speed.

I have a Random Sweep release. If I want to increase clubhead speed, I would either have to make my pulley smaller (more of a snap release) or just increase my hand speed with the same Random Sweep Release.

I was looking at your "Tracing the plane line" post and I noticed your left arm almost pointing at the impact point. there would be no accumlator 3 left and therefore no belt effect. Maybe, extensor action below plane and pulling everything inwards to make yourself feel as skinny as possible(that is the feel I try for arms in and together weight balanced on inside of feet and TURN around spine - Keep it centered.
Just some suggestions but what do I, a "duffer" know?

BTW - i think the clip is a "stack and tilt" thingie.

Mike uses a MORAD pattern, he was asked if he was using a SnT because he works with Dana Dahlquist and said he is not using that pattern.

Thanks for the suggestions, I need to have many compensations right now (to be resolved in 2010.)

As usual, you are being much too tough on yourself. You are doing a great job and definitely moving in the right direction!

Guys question for you.

If you (when actually hitting a golf ball) had a constant hand speed wouldnt that imply a loss of lag pressure? For Linear travel a zero pressure even? When you reach cruising speed in an airplane your back is not pushed back into the seat anymore right? Deceleration would move over into a negative lag pressure per say, as you start chasing the club, throwaway.

In other words is the constant hand speed of the Endless Belt Analogy assumed for illustrative purposes only? To demonstrate the effects of pulley size on clubhead speed?

It was Lag Pressure Homer wanted us to sustain, right? Wouldnt a constant Lag Pressure require a constant Rate of Acceleration? See 6-C-2 THE ESSENCE (of The Secret) third paragraph. Its a Rate of Acceleration not a Rate of Speed, big implications to Hand Speed there.

I know, Ive been reading about a literal application of constant hand speed elsewhere too. What do you think?

Regards

OB, I was thinking the same thing. I dont' think pressures can be created without acceleration and you can't have acceleration with a constant speed.

for a player that would be a model for the endless belt, what would be an expected ball flight? Low with a little cut?

Hey Slicer, all the best for '10.

To me the Endless Belt Analogy illustrates the effects of delayed release on clubhead speed given a particular hand speed. That maximum clubhead speed is not just about hand speed, effort etc. Each of us has our own unique ideal hand speed that if we go past adds little or even subtracts from clubhead speed given an earlier release.


A smooth, constant rate of acceleration would minimize wobble at the clubhead (the far end of the lever), maintain a constant amount of Lag Pressure and sustain the shaft bend........all good things. When HOmer was talking about "sustaining the lag" this is what he meant, I think. You have to find a RATE of Acceleration which you can sustain from Startdown to well past the ball. To start off too fast is to establish a Rate that you cant maintain and as the rate falls off, (even though you are still accelerating!) you are losing Lag Pressure. For distance, the higher the Rate the better but only at Separation not in Start Down. You must experiment with Rates, Release Points to find the right mix for the shot at hand. You probably dont want a snap release for your average every day half wedge for instance.

Next time you are out driving in your car experiment with lag pressure as felt in your back against the seat and the rate of acceleration. You'll see how even though you are still accelerating that as the Rate of acceleration decreases the pressure at your back decreases too. Constant Lag Pressure equals constant rate etc. Another good reason to put your mind in your hands.

This and Delayed Release are the stuff of "effortless power", Homers "heavy" as opposed to Quick and its best friend Jerky.

In terms of ball flight and the endless belt. The only correlation I can think of is that an earlier Release Point (bigger pulley size) will increase the shots trajectory and decrease the clubhead speed for any given hand speed. Imagine a floaty half wedge say with an early release vs a more delayed low spinner. Maybe thats the low cut you referred to above?

So the Release Point can be a Machine Adjustment, shot making tool for the better player. One of many, heck so is throwaway even. I see a lot of tour players using them both intentionally, a bending left wrist and full sweep release when they are around the greens. Swinging the clubhead instead of the hands. See 10-3-J Pause Minor Basic Stroke, but imagine a bending a left wrist and a vertical hinge instead of what Dianne is doing in the photo. You throw the clubhead past the hands, intentional throwaway for intentional compression loss and maximum clubface lay back via the addition of Vertical Hinging. Lynn teaches this shot actually. Cool stuff. Below is a photo of Jim Furyk doing one. I saw Geof Ogilvy do a little chopper from deep rough at the Memorial ..........his hands hardly moved at all he just swung the clubhead up and then threw it right past the hands with a bending left wrist. It went about three feet up in the air and landed about two feet away and trickled down the green towards the hole. What we'd call a "Pause" with a vertical hinge. How the heck Homer Kelley figured that one out in his garage, Ill never understand. I doubt anybody showed it to him.

I wish there was a thread around here for these shots the pros play. Lynn blew me away with a TGM breakdown of a little pitch shot Steve Elkington was doing. We appear to have lost the photos in the move to the new site but here is the link:

Conveyor Belt
 

I always thought of Endless Belt to be like the conveyor belt that delivers luggage at an airport. When the bags are moving on the straight line part they are going at a constant speed and easy to lift off. As soon as the bags reach the pulley portion of the belt they speed up and are difficult to catch, never mind lift off.
The bigger the pulley the slower the bags move. The smaller the pulley the faster the bags move.
At start down the hands are moving on the straight (linear) portion of the belt. Constant and steady pressure. When the reach the pulley part (radial) they are whipped around.
In the link it looks like Mike is using a big pulley.

Thats what I saw as well and my understanding is just as you describe that when the club takes that turn it speeds up but its a constant movement, not some hurky jerky motion with the hands to swing the club faster.
