[O.B.Left]

Mr Left,

Very interesting discussion in spite of the handicap you have introduced.

There's something intriguing about Daryl's analysis about how straight the right forearm is, depending of the club.

It has implications for impact alignment. The pivot need to be more turned through with a driver than a wedge or so it seems. The position of accumulator #1 and #4 at impact will be different for the two clubs. Basically there will be more left with a driver since the right elbow will have more bend...

Not sure where this ends, but it has consequences to how low point is produced ...

Everything else equal means that hands will be relatively more forward when the right elbow is straigher, thus more forward with a wedge than with a driver....

Of course to analyse these differences properly, the left shoulder can't be regarded as the swing center

Hah , thanks B.

Yes the model , as ive called it (so I dont have to keep writing the geometry of the circle over and over)... is very limited when compared to the multi levered human body. There's much to consider there for sure , absolutely and how the human must interact with various clubs , lever lengths etc :

MOI, Hook Face, Straight Away Position, Aiming Point Procedure, Release Point, etc etc etc .

But before we get into all of this stuff let alone where the centre is , where low point is lets try to understand a more simplified model . Once understood we can tack on additional mechanics , levers , face manipulations , release manipulations , move the left shoulder as centre of the arm swing forward , out and down and then Up and In along its own path etc with implications to low point as the dirt sees it anyways.

Or so I hope .. I dunno if we'll get there or not. TBD.

The geometry of the model is very basic , more basic than the machine of 1-L which can double hinge etc. I have a feeling Homer examined the 2D geometry of the circle and then saw the need for the machine. If so Homer's been right where we are right now.... seeing the limitations of the basic model vs a human multi levered system.

However, IMO theres much to be seen in just the simple circle laying flat to an inclined plane. Its already showing:

-how the 2D circle given plane shifts can create 3 dimensional clubhead paths ... best viewed from the down the line. With no change to the plane line base line. 1-L-18.

-angled hinging.

-what the correct clubhead path should look like to the golfer given different plane angles.

-what steering looks like to the golfer.

-what the face should look like in startup to the golfer (assuming angled hinging). You need the machine of 1-L to see vertical and horizontal.

How many golfers can say they know this geometry? Its not a golf thing or a Homer invention its just the geometry of it . It just is, IMO.
