3Jack's Translation of TGM: Part 8G

7-18 (Left Wrist Action)

Left Wrist Action is classified according to the changes in the Left Wrist condition prior to impact. The downstroke changes are opposite of the backstroke, but not necessarily occuring at the same points of the stroke. For instance, the left wrist may cock on the backswing and thus it will uncock on the downswing. But it may cock in the backswing when the right forearm in parallel to the ground, only to not uncock until right before impact.

Trigger Delay alters little geometrically, but magnifies the physics.
So the geometry of the swing won't change much if you increase your trigger delay, but it will increase the physics, particularly Force (Force = Mass * Acceleration), trigger delay essentially magnifies the Acceleration.

Homer then talks about the 'Paddlewheel' action. This is the action the 'hitter' makes. Basically Homer is stating that the right arm moves like a paddlewheel on a steamboat moves. Here's what the paddlewheel looks like.

And from there Homer basically explains how the golfer who uses the paddlewheel action will increase power with more trigger delay. But remember, per the Endless Belt Effect (2-K), the hand speed stays the same, but the clubhead speed gradually increases. But with Trigger Delay, the greater the trigger delay the more rapid the paddlewheel action becomes.

7-19 (Lag Loading)

There are 3 different types of procedures the golfer can use to create lag in the downswing:

Drive Loading (Hitter)
Drag Loading (Swinger)
Float Loading (Hitter or Swinger)

Incorrect Clubhead Lag Pressure 'Feel' does not set up a steady driving pressure but a convulsive, impatient THROWING pressure, guaranteeing Clubhead Throwaway.
There's a reason why I think there's a difference between 'throwaway' and 'flipping.' I think 'throwaway' is basically losing a bit of the primary lever assembly whereas flipping has a bent left wrist at impact. This is because Homer states that 'if the thrown Clubhead doesn't pass the Hands until after Impact Fix Position is reached, it still complies with the Law of the Flail, but precision Timing and Clubface alignment becomes difficult.'

I think 7-19 is extremely important to understand because not only can it teach the proper mechanics behind how to lag the club and the variations of how to lag the club, but it stresses that this loading is a STEADY DRIVING PRESSURE not a convulsive, impatient throw.

The swish drill is a good drill to understand the steady driving pressure and the steady acceleration of the clubhead thru the impact interval. Once the golfer can understand how to get maximum acceleration of the clubhead at impact and then understands how to hit down properly enough on the golf ball (with the irons), they'll reach the #1 alignment in the golf swing, the flat left wrist at impact. Here's a video of the 'swish drill.'

For some reason the function of the right wrist seems to be unclear for the majority of the golfers. Even Shawn Clement talked in his video about the both wrists cocking and uncocking simultanously, which obviously is impossible as far as we talk of a swing that is based on the flat "left wrist law".

'throwaway' :
I think throwaway almost invariably causes the straightening of the right wrist, which equals bent left wrist AKA flipping.No matter if it happens sooner or later during the swing sequence, the pressure in the impact is lost.

Sorry, but I just fail to figure out the meaning of the "paddlewheel metaphore" in this context.

Anon 1...I think paddlwheel really means the image of the right arm pushing on one of the spokes of a paddlewheel. Atleast that's how I interpreted it.

The spokes in the paddlewheel IS the right arm.

Paddle-wheel is a motion of the right hand. The Hand doesn't turn or roll. Like the paddles on a paddle wheel, the palm of the right hand is facing down plane from release to both arms straight.

Paddle Wheel motion works well for a Hitting Procedure because while the Right Hand is Facing downplane then Right Arm Thrust will Uncock the Left Wrist down-plane.


Throw-away refers to losing control of the Clubhead. This generally occurs when lag pressure is lost because the clubhead is no longer following the direction of the #3 Pressure Point.

The term has numerous applications. One example is the Bent Left Wrist through the Impact Interval. As the Clubhead speeds past the hands, even if traveling on the intended path, the hands have launched the clubhead and have given up control.

Even if done intentionally, the term throw-away still applies. So Throw-away isn't always a negative.
