I think what I was missing in this is that even if the clubhead bottoms out and takes a divot in the middle of the stance......Low Point is still Left Shoulder because....

....the HANDS continue down to Low Point....Left Shoulder.....

Uh? Uh?!?!?

Nope...Yoda, please elaborate for birdie and clear the fog. :)

Jim and Birdie...

The left arm is the longest (or most extension) the arn can be from the body in a golf swing, no?

So....the furthest the club can be is opposite the left arm, no?

Hence.....low point.

I've never seen someone hit the ball from a position rear of centre and have a divot that reaches past the left shoulder. Obviosly I'm not watching the right people. :rolleyes:

Opposite the left shoulder as viewed from what angle?

Think about the circle, laying on the plane. The left arm from the shoulder down is the radius, but that doesn't mean that you are getting it to the low point, You could be throwing it away early or running out of right arm because of lack of pivot (turn thru). I think!

:-k
Hmmm...

My guess is that there is a theoretical low point and an actual lowpoint. For a stroke where a divot is taken, the clubshaft is bent backwards, and remains bent backwards as the shaft drags the clubhead through Mother Earth. It seems to me that would move the actual lowpoint of the swing back from the left shoulder. For a stroke where there is no contact with the ground (e.g., driver), the theoretical and actual low points are the same.

Any comments?

I thought the below graphics would make for good disscussion.

Tom Bartlett—undoubtedly the smartest GSEB on the planet, had pointed out a couple of dozen other interesting points regarding low point.

I am sure Lynn will have many as well.

Here is the whole post:

In PIC 1, I use a 20° #4 Accumulator (the left arm across the chest) Angle for ALL THREE FRAMES.

The result in the one Mandrin showed in his graphic. The clubhead (End of the lever) would be moving up at impact.


But, in a real golf swing, the #4 Accumulator angle is released from somewhere near 45°, to much less at impact.

In this PIC and the next, the result all TGMers know—the left shoulder moving UP and the clubhead moving DOWN, WITH a FORWARD LEANing shaft—exists.

hi Nevermind,

Opposite left shoulder from a players angle. Keep in mind that clublength will determine (all things being equal) where the divot will start and end - but, regardless, that doesnt change the radius. The low is opposite the left arm - the radius cannot get any longer than that.

great post Brian!

I think the POINT of the graphic is to show that for low point to be opposite the left shoulder, there are other factors involved.

Creating On Plane Force
 

Thanks for these graphics, Brian. Very instructive!

Five points:

1. Per 2-N-1, the orbit of the clubhead is an On Plane Resultant Force -- the product of two divergent forces (one Outward and one Downward).

2. The Axis Tilt (produced by the Hip Slide), along with the Uncocking Left Wrist and straightening Right Arm, produces the Downward Force vector.

3. The Downstroke Right Shoulder Turn (not Left Shoulder Turn) creates the Outward Force vector and also, by virtue of the Axis Tilt, creates the On Plane Resultant Force vector.

4. The Left Shoulder Impact Location (7-8 ) is determined by the Left Shoulder-to-Ball Radius as established in Impact Fix per the Address Routine of 2-J-1. To the extent it lowers 'down and around' in the Adjusted Address and Backstroke, so it must return 'Up and around' to its Impact Location. The amount of forward Clubshaft Lean (2-J-2) is likewise determined in Fix.

5. Without a Stationary Head to stabilize the Pivot and Educated Hands to maintain the On Plane alignments, the precision required of these actions is at risk.
