K and thanks cause this is a sticking point for me......been one for a while now.

So we agree the left arm flying wedge does not lie on the Inclined Plane at Top for all but the "theoretical left arm plane" and the club always lies full length on the inclined plane at all times. And the left arm flying wedge is defined as the Plane of the left wrist cock. So the left wrist will cock and uncock in the direction of the left shoulder but the club will correspondingly move up and down the inclined plane ( not off plane towards the left shoulder) ? How's this happen? Divergent Vectors?

In the video you pointed out, Lynn turns DTL and appears to cock and uncock on the inclined plane as opposed to the plane of the left wrist cock, the left arm flying wedge.......does he not?

And what about 10-2-D grips where the left hand cocks in the same direction as the right hand bends..........does that mean the Left Forearm Flying Wedge has rotated closer to the Right Forearm Flying Wedge, that they are no longer 90 degrees to one another?

Seriously this has been a foggy notion for me for a while. And it relates directly to Rhythm in some way ......or Ill have to apologize again ......yes cause in the case of the Left Arm Plane there is no #3 Angle by definition which means that all Hinge Actions have the same associated Travel and therefor the same Rhythm. Back on topic.

Hammerin' Down
 

The Cocking and Uncocking of the Flat Left Wrist does indeed occur on the Inclined Plane. However, it remains a Perpendicular Motion (4-B-0/A/B/C) relative to itself.

Visualize a simple hammering action. The 'standard' motion is performed perpendicularly. However, it is often performed at an angle (on an incline, if you will). The same 'sideways' action occurs in the Golf Stroke.

Thank you Yoda.

I must admit to being confused by how the plane of the left wrist cock (the Left Arm Flying Wedge) is often not the plane on which the left wrist actually cocks (the inclined plane). Perhaps I miss the obvious.

I think I see the confusion.

The plane of the left wristcock motion is up the left arm.
The left arm is not on plane, only the clubshaft is on plane.

So how can the clubshaft uncock on plane if the motion is up the left arm?
Is that it?

Search Party
 

I wrote a post on this exact point several years ago. It wasn't the easiest to write, but I did a respectable job. It would be worth the search to find it!

P.S. Thanks for lifting the 'still' from the video. Nice Turned Shoulder Plane alignments: Shaft through the Right Shoulder. Left Wrist Flat, Cocked, and Turned on Plane. Right Wrist Bent, Level, and Turned on Plane. Clubface perfect. I like it!

I don't think TGM would have surfaced if this was irrelevant. The flat left wrist that was one of Homer's first discoveries - and probably the single variable that mostly caused his early success on the golf course to be highly variable. It's the RPM difference that breaks down the Flat Left Wrist.

The flip is embedded in the geometry and the external physics of the stroke, and unless you deliberately do something to prevent it (and know what it takes) it will happen.

Rhythm isn't just about resisting CF. But CF makes it really difficult to obtain a good rhythm.

I think ther's some gradual wrist rotation going on. So that the wrist cock motion is on the inclined plane even thought the LAFW will always be more vertical than the plane.

I have a little home video of you DTL doing much the same but with two arms attached saying the "the right arm lifts and lowers , lifts and lowers .......on plane ....there's the Throw ....on plane...." or similar. Priceless. If you ever want it I could put it up on Youtube. Maybe its already covered in Alignment Golf.

I only meant that it was irrelevant to my perspective of RPM. :oops:

Friendly Force
 

Actually, Centrifugal Force -- more precisely, the Centripetal Force that produces it -- is the essence of Rhythm. As an example, the string (centripetal force) holding a whirling ball in orbit has no problem maintaining its tension and staying straight (thereby maintaining its in-line rhythm).

The problem we have in golf is that it is easy to override Centrifugal Force, usually with Off Plane Clubhead Throwaway. "We has seen the enemy," said Pogo, "and it is us."
