We are seemingly not on the same page.

You wrote-: "We're (me, myself and I) talking about only one of those 6 DOF's. We're talking about ROTATION about the Z axis in our arbitrarily defined golf swing coordinate system."

You might be writing about rotation about the Z axis. I am not - I am writing about how the left hand rotates in space during the golf swing and drags the Z axis with it so that both the left hand and the Z axis rotate as an unit around the instantaneous axis of rotation of the flat left wrist/hand. I do not believe that the left hand is applying a torque force around the Z axis when the flat left wrist/hand moves in space. I think that a torque force around the Z axis only develops if the body stops rotating post-impact and the arms keep moving uncontrollably around the stalled body. The key to a good golf swing is keeping the arms rotating in synchrony with the pivoting/rotating torso so that the flat left wrist/hand rotates slowly in space. If a golfer follows AJ Bonar's recommendation in the next photo, then he may be applying a torque force around the Z axis.

I have nothing to add here. I just hope A.J. got paid for wearing the watch!

YodasLuke got a little impatient with all the theoretical mumbo jumbo and decided to get out the 'big club' and ball we keep around for demonstration purposes. They come in handy for communicating the finer points of TGM (such as Hinge Action). Hard to miss that Clubface!

So, does the Clubshaft rotate onto the Sweetspot's Plane or vice versa? Ted decided to put this argument to bed once and for all. Click here and see for yourself . . .

We're having a little trouble getting the link to take us all the way into the Finish Swivel. But stay tuned, we're workin' on it!

By design, it is definitely a Swing (with its Horizontal Hinging). When Ted emailed the clip over, he even added this P.S.:

"It's not a bad Swing for a Hitter!"

Thanks Yoda for that,(wiping sweat from brow),to see Ted doing this with Hitters pattern would in my eyes be a gem (big club) I would pin that up beside hitting stickman,that would clear the fog for many a hitters learning process.
Thanks again

I'd agree that "swing " looks really good. Ted when do you get a set of these from Henry Griffitts?
