This is such a great post I can't resist commenting but I didn't want to copy the entire post because there is a limit to storage space.

Just so we agree, because the Terms are really confusing. "Turn and Roll" describe the Primary Lever, using a Vertical Left Wrist, moving away from (backstroke) or toward (forward) Low-Point. So Turning is the Primary Lever moving "Away" and the Clubface "Opens" and Rolling is moving toward Low-Point and the Clubface "Closes". For the life of me, I have no idea why HK would use these terms. Swiveling occurs when the Clubface (Left Wrist) changes from Vertical to On-Plane and back to Vertical again.

90 Degree Wedges. If your Left Wrist is Vertical at Low-Point and your Right Forearm Wedge is On-Plane, then the Wedges are at 90 degrees.

Here's where we differ; I think. My opinion is that the Wedges should remain at 90 degrees regardless of Ball Location (its ok if they're not if you prefer it that way). If you play the ball back 6 inches, then, at Impact, the Primary Lever will be Closed but Rolling. It will also be Swiveled and will be Swiveling toward Vertical which it will be when it arrives at Low Point. For the Clubface to be square to the Angle of Approach at Impact, you will need to rotate the grip of the club in your Hands. So at Impact, the Hands will be moving exactly as they would (but on a steeper plane) if the Impact were going to be at Low-Point.

I need to make a "Fine Point". It's pretty advanced but I think everyone can handle it and not lose sleep tonight. "Swiveling" and "Turn and Roll" are not opposites nor are they related. "Turn and Roll" is one concept, separate. "Swiveling and "Hinging" are related. They are Two different ways that the Clubface moves through the impact interval. Hitters Only Hinge. Swingers use a Hinge and Swivel but its not a Hand Swivel. Swingers use a "Release Swivel" whereby as the Hands move down Plane during the Pulley, the Clubface moves from On Plane to Vertical at Low Point. This Swivel is compatible with Hinging whereas Hand Swivels are not.

There is a substantial group of articles by Kelvin Miyahira
that have some great pictures. If, for no other reason, the pix alone are their review.

Thanks D.

Id personally would just say Left Hand above.

The clubface given what Homer termed Grip Rotation may or may not align to plane at Top , may or may not be vertical at Low Point. May or may not be parallel to the left arm at the top of the backswing as is commonly held. But ideally the Left Hand lays flat to plane at top. My right palm lays flat to the bottom of the plane too. But I have a vertical/vertical grip type. As I assume you must.

I lost sleep;
"EXACTLY", the best you can put it into words. Where does the "release swivel" occur for the swinger?

The Release Swivel starts at Release and ends at Both Arms Straight.

2 Choices. 2 very simple demonstrations.

Release with Extensor Action/Throw-out Swivel
Release with Extensor Action/Drive-out no-Swivel

Demonstration 1 - Swingers:

Right Arm only.
  1. Place your Right Elbow at your side, bend your Elbow 90 degrees with the Right Palm facing up.
  2. Lower the Palm while keeping the Elbow at your side. This is Extensor Action.

So, straightening the Right Arm by lowering the hand caused the Clubface to change its Alignment from On-Plane to Vertical for impact and the Right Hand became Aligned with the Elbow and Right Shoulder. Extensor Action without the #1 Accumulator.

So, the Release Swivel begins when the right arm begins to straighten (Release) and Ends when the Right Arm is Straight (Both Arms Straight).



Demonstration 2 - Hitters:

Right Arm only.
  1. Place your Right Elbow at your side, bend your Elbow 90 degrees with the Right Palm facing up.
  2. Straighten the Right Arm by pushing the Hand away from you (Don't lower the Right Hand).

So, straightening the Right Arm by pushing the Hand away caused the right Elbow to move into a straight Alignment with the Hand and Shoulder. Straightening the Elbow by using the #1 Accumulator does not change the Vertical Clubface Alignment. Extensor Action with the #1 Accumulator, no Swivel.


These demonstrations can be easily performed On-Plane with the Right Forearm Flying Wedge. I think that a lot of the confusion occurs while trying to understand and use Extensor Action. Extensor Action is not the #1 Accumulator however, it does use the same muscle group and they can be used simultaneously.

I now realize that we have much different geometry.
my left stays flat, wertical and moveing from cocked to uncocked-release to both arms straight.
My right stays vertical, level and bent and only releases bent as necessary after impact.
This, for me , is dual horizontal hinge.
The bones in my forearms do not change their relative position, release to arms streight.
We therefore have "differences" in extensor action application.
I thing I am OK with what HK wrote.

Well, Vertical to the ground at Impact, for the Left Wrist, is also Vertical to the Plane of the Left Wrist Cock. But for the Right Forearm Wedge, Vertical to the Ground is not the same as Vertical to the Plane . Both Wedges are Vertical to their respective Planes at Impact. That puts them at 90 degrees to each other.

It doesn't sound like your Right Forearm Wedge is On-Plane at Impact.

I "fly" the wedge down the plane. Like a flying wing. Because everything is turning about a remote center ("head") my elbow is moving -on plane - an my shoulder is moving and supporting the hands.

That is what I do- may not work for others.

Ok. I'm just trying to get this clear in my head.

Impact:

Right Wrist is Bent
Right Wrist is Level
#3 PP and Elbow are On Plane
