Putting Geometry

[Yoda]

"If the Ball is struck before Low Point with an upstroke Motion (most obvious with the Putter) disrupting the Clubhead Orbit and the Hinging, then the Ball and the Clubhead Path become circles "exterior" to each other (like two meshing gears)and the line of Compression rotates away and produces a no-spin floater, or Lob Shot. The circle of the ball must be "interior" to the circle of the Clubface orbit and as immoveable as in a spinning centrifuge."

PS- Now we need Lynn to tell us what "circles exterior" to each other are. GO LYNN GO!!!!

In a true Three-Dimensional Impact (Down, Out and Forward), the circumference of the Ball lies interior to (or "inside") the circumference of the Clubhead orbit. Specifically, the Ball lies interior to the orbit of the Leading Edge of the Clubface. Thus, during Impact, the Clubface and Ball become one unit within the same orbit, welded together at the Point of Compression.

In the Upstroke Motion described above, the circumference of the Ball lies exterior to (or "outside) the circumference of the Clubhead orbit. This means that the Ball will be struck by the Leading Edge itself and cannot be 'trapped' within its orbit. Thus, the Compression Point is lost, and the Ball simply rotates away.

In pics 3 and 4 the head is in a different position, centered for the shoulder stroke and tiltted in the arm stroke. SHould these be different? Can you center the head for arms only?

Bgolfing,

The head should/can be centered in both strokes. Sorry if you see any distortions from that "sameness."

VJ - I have noticed that many more players have the toe slightly off the ground (as opposed to the heel). If there is an error in the lie angle of a putter, is it better to have it slightly more upright than down? How important is it to have the lie precisely right?

Thanks - Bruce

Dealing with aim.....the lie angle of the putter is the utmost of importance. Having the toe up will result in left aim...having the heel up will result in right aim. That is...until the computer compensates for it either in aim or stroke path or hinging or.......all three or.......none at all.

To answer the question: Get the putter sitting level!
