I don't need to draw lines on those photos for forum members to mentally picture the location of the upper swing center. It is defined as a point midway between the shoulders - which is roughly a point within the chest cavity a few inches in front of T2 vertebra. That point is about 2mm south-east of the C7 blue dot in those photos.

Just draw the lines, Jeff.

You've made this a big deal, and it is a big deal. You've been drawing lines for some 90 posts in this thread, and I've studied and appreciated every one. Don't wimp out now . . .

Just draw the lines.

:smile:

Yoda - I got stuck trying to draw those lines.

I have lost confidence in my ability to accurately locate the upper swing center.

I can see the right shoulder. Now, I have to mentally "picture" where the left shoulder is located - which depends on the degree of shoulder rotation and the angle of the shoulder turn relative to the ground. I cannot clearly "picture" where the left shoulder is located in this birds-eye view where the upper torso is so spiraled. Can you offer any advice?

I truly value your visual and textual additions to LBG. Thanks once again for your insights!

On this assignment -- thank you for your indulgence -- I gave you an explicit directive:

Draw a vertical line between either of Homer Kelley's recommended Pivot Centers, i.e., the Turned Head or the 'Point between the shoulders', and the ground. Take your choice . . . there's only a fraction of difference between the two (if that).

In other words, the pressure's off: I'm not looking for an assessment of your nouveau "Upper Swing Center" or its relation to the Left Shoulder's Rotation or the Spine's Spiral.

[Great stuff for a new thread, though. Have at it! :smile: BTW, with all due respect to your term "Upper Swing Center", Homer's term Pivot Center works better for me. There can be only ONE Central Axis in a Centered motion. Your term implies there are (at least) two: An Upper and a Lower. Now, that may well be your model (if so, please address that, too.]

For now . . .

Please just draw a vertical line between your preferred 'Homer Center' and the ground. Personally, since you've asked my advice, I'd start with a vertical line touching the left side of the Turned Head.

:golfcart2:

Thanks!

Yoda - here is a revised image with red lines drawn alongside the left side of the turned head.

I started to use the term lower swing center after reading the Golf Digest S&T article, where Bennett/Plummer used the term to indicate a point midway between the hip joints.

Thanks for this work, Jeff.

Homer Kelley and his advocates (including me) have taken a lot of heat in some quarters for his teaching that the "true Swing Center ... is around a Hinge Pin ... precisely between the feet" (2-H / 7th edition). Your work provides ample proof that he was right . . .

Again.

It appears to me that Player is off plane at the top with a bent left wrist.
Palmer arched left wrist. Nicklaus and Souchak flat left wrists. What do others see?

I moved this post to another thread, "Clubshaft Alignment at the top".
