I find that 10-18-C description very interesting and very new to me - as it implies that there is horizontal/angled/vertical hinging actions in the backswing. I cannot understand this biomechanical phenomenon. Does HK describe the biomechanics of backswing hinging actions? I can understand the followthrough hinging actions as being due to a variable degree of external humeral rotation happening at left shoulder socket level, and I can conceptualize the biomechanical process.
However, what is happening biomechanically if hinging actions are actually occurring during the backswing?

This is the reason I discussed hinge action and when "should" (I know there are no options...) an intended hinge action make it's presence known in the golf swing.
Homer was always keen on backswing feels mimicking downswing feels...snap load with snap release.... takeaway swivel with release swivel....the same can be done with hinge action it appears - no?
In the Cuscowilla homecoming thread several people saw Yoda and Golf Guru do full swing vertical hinged 6/7 iron shots....somebody asked if they did a "reverse roll"/vertical hinge in the backswing (ie. hinge action "prep feel" in the backswing) ....the replies did not apear to deny this action.
If, as some of the science TGM investigators appear to be saying now (as I understand it = Dr Zick for TGM ?) Hinge action actually starts to occur on the downswing then it would appear sensible to start prepping that feel on the backswing ( snap with snap etc...) - no?
Has anybody got any 3D analysis (with back up trackman data) to show that a swinger with intended dual horizontal hinge has the same downswing as a swinger with dual vertical hinge?
As wrist action is intimately connected with pp3 location and loading for swingers....and that is related to aiming point...I hope this is not too much threadjack....sorry!
If there are "true" hinging actions happening in the backswing, then I would like to learn more about the phenomenon. I would particularly like to see visual examples.
I am aware that a swinger's action has a release swivel action in the downswing, but I know of no difference in the release swivel action of a swinger who uses horizontal hinging versus angled hinging. If there is a difference, I would like to learn more about this difference.
In my studies with Alex Sloan, who was a Homer Kelley purist, hinge action was Impact to Follow Thru. At Cuscowilla I wasn't aware of any other context. Lynn talked about closing the door, rhythm, and pointed out that hinging was arm action not wrist action with the selected hinge pin installed at the shoulder. As a swinger I have no hinge "thoughts" on back swing. Only right forearm takeaway with tracing , drinking a beer to top(lifting left arm) with hands on plane. Downswing hands still on plane, taking loaded no # 2 beyond line of sight of ball and with my strong grip knuckles up. At top Delivery line roll prep occurs. Now I guess that includes the intention of taking out the plane line with karate chop performing the selected hinge action with a geometric right wrist. That hinge is performed to finish off the release. Hopefully the pro's that were there will comment on that 6 iron with vertical hinging. Keep it simple.

Techically hinging is just through the impact interval . . . . I'm not really sure about all that hinging in the backstroke stuff. There are probably examples of players that do it . . . . and probably more so in short game situations. For some reason I'm thinking that Lynn has done a video that speaks to this . . . not sure if it is a premium deal or not.
Anyway . . . . I'd say it's more of a wrist action thing than a hinging thing on the backstroke anyway. You can be single wrist action on the backstroke and standard wrist action on the way down. Regardless though if the if the sweetspot and the shaft are in the same plane and "laying on the Plane" they have to eventually come off . . . and then execute the selected hinging (assuming one actually understands and does hinging).
But to you point . . . . a "textbook" or chapter 12 pattern swinger that is using Standard Wrist action by definition would have to swivel the wrist to vertical regardless of the desired hinging (angled/horizontal/vertical) to actually put the face on the ball and not the hosel. But as far as that OPD or OPP or whatever deal from Hardy . . . I don't know anything about him or his patterns but seems to me he's simply describing swinging with Single Wrist Action . . . which is valid. Single Wrist Action isn't exclusive to Hitting. But I'd say much of this discussion also is relevant to grip type . . . for example in the 3rd edition Homer has a 10-2-D grip (strong left hand or Turned Left Hand) pattern . .. . the wrist action is "Angled Hinge" . .. . So the stronger the grip GENERALLY the more the face will be looking at the ball on the way back and THROWN at the ball on the way down.

It may have been a misunderstanding Between Burner and MB... but it looks like Burner confirms a takeaway move which was different to standard....specific to the use of vertical hinge.
Yoda or GolfGuru, could you confirm what you did to achieve vertical hinge on 6 and 7 irons please? Thanks!
