I would like to chime in a bit here . . . CF according Mr. Kelley does produce Horizontal Hinging . . . however according to Mr. Kelley the amount of force required to override the cf acting clubFACE is minimal . . . hence the "manipulated hands swinger." The amount of force required to override cf on the clubhead/shaft . . . different story.
So from a practical stand point if you chose to swing then how can you keep your hinging from turning into an unbridled swivel as upposed to an unpredictable flash of the face? ANSWER . . . keep the massive rotor GOING . . . and keep its mass CENTERED and far enough down the plane line so you don't run out of right arm. So if you "hangback" with the right shoulder via a perverted axis tilt, not enough weight left, or your right shoulder ain't moving down out and forward the proper amounts . . . the dawg runing on the chain gets choked out . . . DO YOU KNOW WHERE YOUR LEFT SHOULDER IS?
"Keep the Rotor going". Nice, we've all felt the consequences of not doing that. I think this maybe ties in with what Slice said too. Is this a maintenance of CF then? If Homer had of slowed the RPM's of twirling string would the face have rolled over?
Do you mind taking us through the photos, what do you see there? Is Adam Scotts COG or Axis of Rotation (in a VJ Trolio sense) not far enough left to your mind? In the comparison of Hogan and Tiger , is it Hogans hips being turned more that you are looking at? The right foot drag move of his that Knudson adopted plays a big part in that I believe although its relates to ones flexibility and is therefor a custom fit kind of deal. Hogans drag was smallish , Knusdon's especially as he got older was longer as he preached getting to Finish in a super comfortable way with your "center" (cog, I guess) pointing right at the target, exactly. But I digress.
I don't think CF produces an over roll. It doesn't produce a roll at all. It produces angled hinging.
I actually thought that CF (or actually angular speed) would add inertia and make it harder to close the club than when it is at rest. But after a brief check on www on angular inertia, coreolis force etc I think the work requred is the same in any case.
The machine have to close the club directly. A level hip probably helps for precision. And a good pair of wedges. A little initial torque from the top or somewhere in the down stroke. And keeping the left wrist vertical throughout. Whether the closing is freewheeling or adjusted by the hands isn't a biggie. The hands know their impact alignments whether they are right or wrong, and the work involved in closing the club is anyway close to nil.
All the cf will do is keep the club moving in circles at a constant speed. It's the radial pp forces and possibly a momentum at the hinge pin that increases rotary speed.
If you let go of CF the club will go way left. Spinning around its longitudinal MOI befor it lands in the dirt.
When I said above that CF produces angled hinging I wasn't intending to exclude horizontal hinging. The spin can be horizontal and therefore also the hinging can be horizontal. Or vertical. if the plane is vertical But not dual.
Perhaps my post's title or question is incorrectly worded from a science point of view then. When I say CF perhaps I should say Radial Force or Rotational force or some such thing.
I think I get what you are saying in last paragraph. So assuming we are on an Inclined Plane somewhere in between vertical and horizontal, an Angled Hinge will tend towards the characteristics of the closest plane be it vertical or horizontal. Is that what you mean?
In that case, Homer's string demonstration, didnt/couldnt display horizontal hinging but rather an Angled Hinge.

What I see is right shoulder geometry in action . . . look at Hogan's right shoulder (Lynnard LBGreengenez too!) compared to Scott at start down. Scott's right shoulder has already ducked under his left shoulder . . . axis tilt already starting to kick in. Take a look farther into the swing and compare where Eldrick's right shoulder is compared to Hogan at a similar spot in the swang . . . Hogan's right arm "runs out of chain" way later than Eldrick and Scott too . . . Eldrick's gettin his tilt by his head going back vs. Hogan who get's his axis tilt from his hips going forward. Look at Scott's wrist just past follow thru . . . he's rubbing forearms together (you can get thrown in jail for that down here) . . . but do you think he's trying to do that? Or can't help it?

Thanks for sharing Bucket. You're giving away some of the secret spices and herbs here. Awesome.
