Cross-Line Thrust Through Billions of Parallel Plane Lines

1. Straight Plane Line (no cross line cra..)
[Bold emphasis by Holenone.]
First of all, the quote above --
"cross line cra..."-- is not my error. Unfortunately, it is directly from our host,
Brian Manzella.
In one dismissive and mean-spirited 'three-letter' word--
"cra"p -- he dispenses with the
Outward Dimension of the Three-Dimensional Downstroke (Downward,
Outward and Forward). Indeed, in one deriding 'three-letter' word, he labels
"Wrong!" the essential Geometry of
The Golfing Machine, its Inclined Plane of Motion and the wisdom of its author,
Homer Kelley, who refers many times in his work to "Cross Line." All this despite Brian's post signature,
"The IMPERATIVES should dictate the components -- not the other way around."
Fine.
It is his site.
For the rest of us...
From the Top, the player directs Clubhead Lag Pressure
Down Plane (via its Down-and-Out Delivery Path) toward the
Straight Plane Line (usually the Target Line).
Then, through
Impact, he continues to direct Clubhead Lag Pressure
Down Plane -- Down-and-Out -- via its Straight Line path
through the
Impact Point to the
Low Point (of the Clubhead Arc). Given the In-Line condition of the Left Arm and Clubshaft -- via the
Flat Left Wrist or its
Geometric Equivalent -- this lowest point of the
Down Plane Clubhead Arc is located opposite the Left Shoulder and on a Low Point Plane Line parallel to the Impact Plane Line.
Thus, the Lag Pressure (and the Clubhead)
Cross the Straight Plane Line, i.e., that Line passing through the Impact Point and directly toward the Target. They do, in fact,
Cross through the
Impact Plane Line on their way
toward the
parallel Low Point Plane Line.
In other words, from the Top, both the Thrust of the Stroke
and the Clubhead
Cross BILLIONS (actually, an infinite number) of
parallel Straight Plane Lines on their way
through Impact Point to
Low Point.
And so it is with
Cross-Line Thrust...and the resultant Clubhead Orbit.
It is not the way some people
think it to be.
Or even the way they
wish it to be.
It is the way it
actually is.
And so it will remain for all time.
