Geometry of the circle and how it applies to shot shaping .

[O.B.Left]

Man , thats beautiful footage. Flywheel and one moving in sync with the arm swing. But what the heck does that mean mechanically? We can see it , feel it like MJ says but what is it about those swings that we are so attracted to. Balance, grace , power etc etc . Yes but consider what Homer meant by Rhythm and how the pivot and the arms must move in sync to ensure Rhythm.


Homers concept of Rhythm requires the clubhead , clubshaft , hands , arms to moving as a unit , in line , with a constant RPM about its centre albeit with different surface speeds depending upon how far away they are from the centre. Break the left wrist and break the Rhythm .

But there is an important consideration to be made between the relative rates of rotation between the Pivot and the Primary Lever to ensure Rhythm. Rotation of the Primary Lever being #3 power accumulator , roll power.

The Turning Rate of the Pivot Components – especially the Shoulder Turn as actuated by Hip Action (7-15) – MUST be identical and synchronous with the #3 Accumulator Roll, else its Rhythm gets disrupted. Or at least difficult. This requirement also dictates when and how much Downstroke Hip Slide is needed.

As I read Homer and correct me if you guys think otherwise. He's saying essentially " get the turning rate of the pivot and #3 power accumulator mismatched and the left wrist will tend to break". Club face problems , directional difficulty due to the clubhead swinging ahead of the hands.

So lets say you get your pivot turning faster than your #3 is rolling through the shot. That would logically lead to a shot that goes to the right to my mind as the Primary Lever would be trailing , clubface open. Vice versa for a manipulated Primary Lever that rolls faster than the pivot is turning.

A further complication is that the relative effort needed to rotate the pivot vis a vis the #3 is different.

I have this sneaking suspicion that when good golfers hit a bad shot its a Rhythm problem , but born out of a mis matched Pivot and Primary Lever rate of rotation. Tension can do it . Over acceleration , quitting.

BTW our old buddy Ted Fort is a genius when it comes to coordinating out of sync pivots and primary levers. He's got some drills that may some day be common fare on practice tee's the world over. I highly recommend him for anyone whose interested in a lesson. Hitters or swingers.
