This Plane Angle is applied to a line that is on the surface, the Plane Line 7-5/10-5. It is defined as the base line of the Plane.

The Inclined Plane Line is parallel to the Sweet Spot Plane Line (which is often considered to be the Target Line or Line of Flight Line and is defined as the Impact Line 2-N-0 which definite lies on the Sweet Spot Plane at all times)

Of the two primary Planes in TGM, the Inclined Plane is the plane the clubshaft travels on and the Sweet Spot Plane is what the Hands monitor the Feel, the drag/lag, motion, etc. (This may be refuted by others). I posted a thread in the lab about the Inclined Plane.

thanks for the response...yes it's those threads in part that have started me thinking about this...i have my own thoughts on what points one uses (or can use) to define these planes...the the named body part (ie turned shoulder, elbow) is one, but what about the other two?...i'd like to hear some other ideas (especially from those who have talked with HK)

I would think one of the 3 points that define the Plane would have to be on the Plane Line. How about the Hands and a point on the body defining the other 2 points?

The "three points" you refer to don't necessarily define the shape of the plane. You can have planes that are shaped like rectangles, circles, squares, triangles or any shape.

However, any plane can be defined by any three "coplanar" points -- i.e., three points that are lying on the plane you wish to define. Thus, you can have three points -- A, B, and C -- on a large circle-shaped plane. Lines drawn between the three points would describe a triangle -- but those three points would still define to which plane you refer(as would any other three points on the same plane).

For example, you could describe a street as Mr. Brown's street or, his neighbor, Mr. Green's street. That would identify the street, but wouldn't tell you the shape of the street.

Most people think of The Golfing Machine plane as a huge rectangle -- and, it could be. It could also be a large circle, square, etc. Mr. Kelley never described the shape of the plane -- he only said that it had to be larger than the cirucumference of the club being swung (2-F).
