In this thread, at least once and maybe more, the following statement has been referenced in 2-G, Hinge Motions.
Quote:
"The Clubface can make three motions through Impact--Hood, Close, and Lay-back."
I do not believe that this is the case. Could you please give your thoughts and/or opinion on how Hooding is or is not, a clubface motion?
Thanks
The "Three Clubface Motions" quote above is directly from 2-G in the6th edition and is consistent with Homer's presentation of the Clubface Motionsin prior editions. In all editions, he promptly discarded the Hooding Motion asuseless except to impart true overspin in Putting via an above center Impactper 2-C-4-#2. Regarding the remaining two Motions, the player may employ one(Close Only -- Horizontal Hinging) or the other (Lay Back Only -- VerticalHinging) or both simultaneously (Close and Lay Back -- Angled Hinging).
Many students of our Hinge Action -- A Primer thread on the Forum TheGolfing Machine have built a Hinge Apparatus that allows them to produceeach of the two Basic Clubface Motions -- Close Only and Lay Back Only -- andalso their Composite Motion, i.e., Simultaneous Close and Layback. Theyproduce each of these Motions scientifically by positioning the model's HingePin Vertical (or perpendicular) to one of the Three Basic Planes of Motion,i.e., Horizontal, Vertical, or Angled. The Blade of the Hinge revolvesaround its Pin and likewise remains Vertical to the chosen Plane of Motion. Whena Clubface is attached to the Hinge Blade, its Motion around the Hinge Pin isidentical to that of the Blade, i.e., it remains Vertical to the AssociatedPlane of Rotation.
The Hinge apparatus cannot produce a Hooded Motion. That isbecause the Blade of the Hinge (to which the Clubface is attached) is alwaysVertical (perpendicular) to its Plane of Rotation. To Hood an attached Clubfacevia a true Hinge Action, the Blade of the Hinge would have to be tilted to anangle of less than 90 degrees to its Plane of Rotation. And this violates thevery definition of Hinge Action. You certainly won't find any hinges built likethis at Home Depot!
That said, a player can cause the Clubface to assume a Hooded Position byaltering either his Grip (turning his Left Hand to the right) or the normalBall Location (playing it further back) or both. However, he cannot producea Hooded Clubface by executing one of the Three Hinge Actions. Therefore, Homercame to believe that Hooding was more accurately described as a Clubface"Position" and not as a Clubface Motion.
At the time of his death, his revisions to the planned 7th edition includedchanges in 2-G to reflect this altered thinking. The 7th edition would nowclassify only Two Clubface Motions (or their combination) -- not Three-- as Hinge Actions. Hooding is no longer classified as a Motion, but as a Position.
As I read through these particular revisions for the 7th edition, I had tosmile. He allows one exception to this new 'Hooding as a Position' concept,and that is when it is produced by an "Over-Swivel Motion." Whythe smile? Because that is exactly what he told me in our first telephoneconversation in early June of 1980. "This is the only way to get a duckhook," he said. And then he went on to describe in detail what an effortit took for the duck-hooking player to make that kind of rotation and toactually get the Clubface on the top half of the Ball.
I can tell you that I owned the left side of the golf course at that time, andit seemed like no effort at all!
