Magic Of The Right Forearm / Elbow Action

[Yoda]

Yoda,

1. I've read a few of your posts on wrist positions. You emphasize the fact that the right wrist NEVER cocks. I just don't understand how I can cock my left wrist WITHOUT cocking my right. It's just not possible!

2. Also, by the same logic, a bent right wrist guarantees a flat left wrist, doesn't it?

3. Another question, is the left wrist allowed to bend after the follow through (both arms straight) or is it only allowed to roll?

1. It is not only possible to maintain a Bent and Level Right Wrist while Cocking and Uncocking the Flat Left Wrist, it is mandatory. Study the Flying Wedges (6-B-3-0-1).

2. Maintaining the Right Wrist Bend guarantees a Flat Left Wrist, but only if the Right Wrist Bend is precisely the amount established at Impact Fix. If the Bend is less, the Left Wrist will be Bent. If more, it will be Arched. Be aware that the further Forward the Ball is positioned, the greater the amount of Right Wrist Bend. And the further back, the lesser the amount.

3. After the Follow-Through, the Flat Left Wrist Swivels back against the Plane and then Bends as the Right Wrist Flattens (Right Palm down to the face of the Plane). This is the reverse of their positions in the Backstroke. At the Finish, most really good players have restored the original Flying Wedge alignments, i.e., the Flat Left Wrist and the Bent Right Wrist and their perpendicular relationship to each other.

It never actually passes the hands because the hands are still thrusting....but the shaft, due to its whippiness, does bend because it is being overtaken by the clubhead and this is the bow we see. If you were to do the same with a thin iron bar, you most likely wouldnt be able to catch the bowing on camera - because an iron bar most likely could withstand the overtaking motion of the clubhead and the increased mass wouldnt affect it as much. All of this is due to the Conservation of Angular Momentum as explained in 6-C-2-B: "The clubhead 'overtaking' speed is governed by the Law of Conversation of Angular Momentum whereby the increased Mass resulting from any extension of the swing radius decelerates the Hands and unless they are supported by Power Package thrust or throw out action. can result in great loss of clubhead speed." . I don't quite understand how the mass was increased. Nothing was added just the configuration on the arms. In moving the arms outward the moment of inertia of the skater changed but not the mass. No mass was added to the club, no mass was added to the arms, I don't understand??

Jim...

Good point. I misspoke somewhat - what is actually happening is we are increasing the radius. Strictly speaking, we haven't really added mass. However, the term used in the explanation to me was 'effective mass'. I guess what this does is increase the moment of inertia by redistributing the mass of the rotating force.

Does that make more sense? Let me know if I am off in any of this - the purpose is to understand it.

In a punch basic stroke do you feel the right arm flying wedge intact all the way down to the ground in front of the ball?

JG33,

For all Strokes, the entire Flying Wedge Assembly -- Left Arm and Right -- remains intact at least through the end of the Follow-Through (the Both Arms Straight position).

I'd say Venturi would agree with your 'cast' feel

Yes, I remember an article Ken did on the short game years ago where he put both wrists and forearms in casts. In addition to preventing any Left Wrist Bend, the Left Wrist/Forearm cast precluded the Wristcock. This would be another helpful image because you would rarely use the Wristcock -- the Velocity Accumulator (6-B-2) -- in a Single Barrel (10-4-A) Stroke.

Incidentally, I have previously commented on the mistaken notion that maintaining the 'Locked' and 'Frozen' alignments requires a tight Grip Pressure. It is helpful to realize that the 'cast' that 'freezes' the Right Wrist in its Bent and Level Impact Fix alignment does not prevent the Wrist within that cast from remaining in an inert, unstressed condition from the Top through Impact per 4-D-1. In other words, the cast is one thing and the degree of tension in the Wrist is quite another.

Dear Yoda,

I went out to the range today and tried my version of "hitting" with a frozen right wrist. The crossline delivery path of the hands is easier with a more rigid right forearm flying wedge. I also tried pushing the handle back with the right thumb pressure. It seems more structurally sound. Should the #3ppt push on the back of the handle on the downswing, without any rotation, in a straight line path to the aiming point if one is using angled hinging?

Yes. Regardless of the Hinge Action employed, Clubhead Force and Motion is always On Plane at right angles to the Sweetspot (1-L #10 and #11) and also to the Clubshaft (7-11). At the Top, Hitters Drive Load (10-19-A) the Clubhead Lag Pressure with the No. 3 Pressure Point at right angles to the Aft side of the Shaft and that Loading is maintained through Impact.

Swingers, on the other hand, Drag Load (10-19-C) the Lag Pressure at right angles to the Top of the Shaft. That Loading is maintained at least into Release, at which time the Swivel may or may not cause it to return to the Aft side of the Shaft (10-11-0-3). If it does not, the Swinger who began with a Strong Single Action Grip (10-2-B) has now changed to a Weak Single Action (10-2-A).
