10-6-0 Basic Plane Angles

[Yoda]

yoda,

Will you go into more detail on the location of the sweetspot plane? That is,
where it starts(the sweetspot), its relation to the #3 pp, where it touches the body, etc.

Thanks,

Could you give me some clarification here:


You wrote on the forum,

The 'traditional' Plane Shift(s) exist(s) because Homer originally thought that the Inclined Plane related only to the Clubshaft. Over time, he came to relate the Plane to the Sweet Spot, a point an inch or so outside the Shaft Plane. Most Backstrokes require a shift from the Clubshaft Plane to a Plane of the Turned (or Turning) Shoulder. However, Backstrokes made from the Sweet Spot Plane require none.

"Any Plane Shift is hazardous." -- Homer Kelley



My understanding is that the sweetspot plane starts at the sweetspot and passes through #3 pp. That would make it be flatter than the elbow plane at address, and also flatter that the turned shoulder plane.

Is the sweetspot plane moving in its inclination to the ground as we swing? What would be ideal?

I'm having a hard time visualizing the sweepspot plane as viewed from Down the Line.

Thanks

Ldeit,

You are correct that the Sweetspot Plane passes through the #3 Pressure Point. During Release and Impact, it also passes through the Right Forearm. However, these alignments define an Elbow Plane only when the Plane Angle passes through the point of Elbow contact with the waist per 10-6-A. This is considerably Flatter than the Turned Shoulder Plane Angle.

The soles of most Clubs are cambered to enable the Club to be positioned between the Elbow Plane and the three Shoulder Planes. The Sweetspot Plane of a Club soled toward the Heel and with a good deal of #3 Accumulator Angle would tend to define the Elbow Plane. The Sweetspot Plane of a Club soled toward the Toe and with minimal #3 Accumulator Angle would tend to define a Turned Shoulder Plane.

Ideally, you are going to swing on that Plane defined by the Angle of Inclination between the Sweetspot and the Turned Shoulder. With a properly positioned (On Plane) Right Forearm at Fix, there will be a minimum of Left Arm and Club #3 Accumulator Angle. In Start Up, the Right Forearm immediately takes the Club Up, In and Back on this Turned Shoulder Plane. Any attempt to keep the Club 'low' or 'along the Line' will result in a Shoulder Turn Takeaway, Pivot Controlled Hands and a necessary Plane Shift.

The Downstroke also uses this Plane...Zero Shift.
