I'm sending you some frightening pictures too :eyes:

Annikan, Can nothing be done about this!!! :exclaim:, word has it that you have access to 12 Piece- what if we sent you a little CASH!

Seriously my forum friend Mr. 12 Piece- AKA 1/2 of a golfing Machine- hey- everyone's gotta start somewhere! Post a new thread and I guess we could bat it around a little.:)

He is, of course, talking about Conservation of Angular Momentum (COAM) the effect we see when an ice skater spins faster by pulling her arms in towards her, and slows when she extends her arms.

In TGM terms:
7-18 LEFT WRIST ACTION
...
With the Endless Belt Effect, The Belt (Hands) and the Clubhead have the same RPM but the Surface factor sets in and gives the Clubhead greater MPH - in reverse proportion to the size of the Pulley (the smaller, the faster). That is, raised Hand Position - reducing Accumulator #3 Travel - plus Trigger Delay. Conversely - a larger Pulley (lowered Hands) requires a higher Handspeed and an early Trigger. See (6-B-3-A), (6-F-0) and (6-N-0).

The backswing is about coiling the the upper body against the hips. When tightly coiled, the hands are higher ("raised Hand Position" -- small pulley), but an early hit from the Top or End causes the hands to drop ("lowered Hands -- large pulley").

"The Four Magic Moves To Winning Golf" by Joe Dante was my bible prior to studying TGM. It was first published in 1962 (like Homer, a man before his time?) and is now available as ISBN 0-385-47776-7.

The above quote was from page 116.

Dante's analogy has to do with the inertia of the wheel and its physical rotation. Kelley's analogy, on the other hand, has nothing to do with either. Instead, the wheel is a proxy for the Release Interval -- the size of the Release Arc through which the Hands pass -- prior to Impact. The smaller the Arc -- the less Clubhead Travel Time permitted during Release -- the greater the Clubhead Speed. For example, halving the Travel Time (Snap Release / small pulley wheel) doubles the Travel Rate (Clubhead Speed). Conversely, doubling the Travel Time (Sweep Release / large pulley wheel) halves the Travel Rate. All this is necessary to comply with the Law of the Flail and the Rhythm (RPM) of the Stroke as the Clubshaft seeks its in-line condition with the Left Arm.

In other words, Kelley's model has to do with the increase (or decrease) in Clubhead Speed with the Handspeed held constant. And that Clubhead Speed is inversely proportional to the diameter of the pulley wheel, i.e., the smaller the pulley wheel (at the end of the Delivery Path of the Hands), the greater the increase in Clubhead Speed during the Hands' encounter with it.

Thanks Yoda, for that explanation.

I can understand that there is an increase, but double?
