plane and pivot
 

Can someone explain the basic difference between the various shoulder planes. The turned shoulder plane, turning shoulder plane, square shoulder plane and rotated shoulder plane.
I find the application can be confusing.

For me this plane would be the basis for pivot controlled hands.

Where as a hand planer,or elbow planer would more likely have a hands or (elbow?) controlled pivot. I tend to naturally use the hands or elbow to initiate the takeaway but been shifting to a shoulder type plane during the backswing. Been experimenting using a shoulder plane when addressing the ball but not as consistent with this method.

Even looking at 10-6-B turned shoulder plane. Which I guess is the most common shoulder plane. Seems to point a line to the right shoulder. But this application would work only if the shoulder start off square to begin with and
the depends on relative position of the left shoulder.
The shoulder is a complex joint. Homer seems vague in the exact postion of the line to the right shoulder. Is it the right armpit? Is it the top of the shoulder?
For clubshaft controlled I would have thought this shoulder line could be more precise.

Shoulder Planes Relationships
 

The "difference between the various shoulder planes" is . . .

The relationship of the Inclined Plane of Motion of the Hands and Club relative to the location of the Right Shoulder:

At Address (Squared Shoulder).

At the Top (Turned Shoulder).

Dynamically during the Backstroke (Turning Shoulder).

There is a Rotated Shoulder Turn (10-13-C), but no Rotated Shoulder Turn Plane Variation. Given (1) Educated Hands and (2) the required Waist Bend, the Rotated Shoulder can locate any of the Shoulder Plane Angle Variations.

The Plane, as you know, is this flat inclined surface that extends from the ground and up, intersecting some point on your body. All of the activity of the golf swing should not disturb the Clubshaft from remaining on this plane. Cocking, Uncocking, Rolling, Turning, Swiveling etc., should all be performed with the Clubshaft remaining flat against this plane. That is called Clubshaft control.

There are various angles of Planes that can be used. Those near the Shoulders can be grouped and named the "Shoulder Planes". Those around the Hips/Waist are called the Elbow Planes.

Swinging, using one plane angle or another, or shifting from one plane to another involves using different procedures to control the Clubshaft for it to remain perfectly On-Plane.

The Shoulder Planes have different reference points (where the inclined plane intersects the body) which correspond to the steepness of the Angle or one of its other characteristics. Each one is named. Square Shoulder, Left Shoulder, Turning Shoulder (type a and b) and Turned Shoulder.

Each Plane may have different performance characteristics as well as different levels of difficulty in achieving consistency. But the Goal is always the same; controlling the Clubshaft.

Thank you for the response.
Had a meltdown thinking about all these planes.


Daryl,
Wouldn't just make more sense if Homer simply call the elbow plane a hip/waist plane?
