So when people talk about a swinger using horizontal hinge action in their total motion, they are actually using dual horizontal hinge action.
That's right, kebeal. It is standard practice to eliminate the word Dual when referring to Dual Horizontal Hinge Action and Dual Vertical Hinge Action. Homer Kelley himself did the same thing.
How can this be done without compromising the precision that is the birthright of The Golfing Machine?
First, other than with Putting and short Chips, anything other than a Dual Hinge arrangement would be extremely rare. In fact, due to Club design and the necessity to stand on one side of the ball or the other, Horizontal Only and Vertical Only Hinge Action are virtually impossible to accomplish except in the short Strokes.
Second, when Horizontal Only Hinge Action (10-10-A) or Vertical Only Hinge Action (10-10-C) is used in the short shots, that specific terminology becomes the differentiation.
And remember, there is no Dual Angled Hinge Action, because the Clubface and the On Plane Clubshaft utilize the same Angled Hinge.
Only 'non-dual' horizontal and vertical when the clubhead COVERS the plane line during the entire stroke...correct?
That is correct, Matt.
The Clubhead Covers -- not Traces -- the selected Delivery Line with both Horizontal (Only) Hinge Action and Vertical (Only) Hinge Action. Thus, the Clubhead remains in a Vertical Plane -- not an Inclined Plane -- as the Clubface Closes Only (Horizontal Hinge Motion) or Lays Back Only (Vertical Hinge Motion).
Notice that I have used Motion as a differentiating term here. The Hinge Action as executed by the Flat Left Wrist (remaining Vertical to either the Horizontal or Vertical Plane) produces a corresponding Hinge Motion of the Clubface.
"Precision is recognizing and reconciling minute differentiations."
And remember, there is no Dual Angled Hinge Action, because the Clubface and the On Plane Clubshaft utilize the same Angled Hinge.
I knows Lynn knows this but want to further elaborate.
There is no dual angled hinge action when the vertical plane of the angled hinge action directly intersects the inclined plane which is the most common usage. However as angled hinge action is anywhere between horizontal and vertical hinge action on an infinite no. of planes and only one of them being directly vertical to the inclined plane the secondary hinge pin (1-L) has to be used.
The more that the hinge action veers towards horizontal from the inclined plane 'pure' angled hinge action, the more the secondary hinge pin will lift in the backstroke and lower on the downstroke and lift again in followthrough on the model of 1-L. Conversely for vertical - lower on backstroke, raise on downstroke and lower again in followthrough...
