Homer assumed Separation to be at Low Point but what if it isnt?
Homer in the diagrams of 2-C , for illustrative purposes (I think) assumed Separation to occur at Low Point. But what if it isnt? What are the implications?

Lynn has said that the impact interval is approx 3/4 of an inch in length , which implies to me that for balls positioned further than 3/4 of an inch back of Low Point, Separation will occur prior to Low Point.

What are the implications of this to the Arc of Approach , the Angle of Approach , the Line of Compression, clubface angle etc etc if any?

In 2-J-3 Homer writes that you determine the Angle of Approach by drawing a straight line from Impact to Low Point. So would I be right in thinking that the Arc and Angle of Approach are unchanged but the clubface angle per 1-L-17 needs to be square to the target at Separation..........

That picture would be a bit of shock to most golfer wouldnt it? A square to the hole clubface at Separation but a clubhead still way back of low point on the Arc of Approach. The clubhead needing to continue its Inside/out journey long after the ball has gone. Most golfers would assume this to be a draw or hook shot deal wouldnt they? But it isnt. Is it?

Sorry I cant do any fancy computer graphics which would help illustrate this. Maybe our good buddy, Daryl could help out.

If this is true , no wonder most divots point to the left ..........a straight line base line has way more Down and Out to it than you'd ever imagine... especially for shots played back in your stance.

Depends on many factors.

7-2 covers the alignments-per grip

because swinging (horizontal hinge) would be vertival club face, on plane lag pressure- Hitting (angled hinge) would be both clubface and lag pressure on plane. Then the low point can be moved a long way by #2 and even to down and out with an up and in clubface {a bad thing but possible}

Impact, Ball Location and Low-Point.
6 Iron. This illustration indicates Impact at 6" behind Low-Point. Ball probably separates at 5 1/2" and Clubhead enters the ground at 5" behind Low-Point. Dirt starts to show at 4" behind Low-Point. Divot depth is 3/8".

Question is: Does one side of Low-Point have more divot? Why?








Innercityteacher played 57 rounds of golf this summer and must have hit thousands of balls. Do you think he ever measured a single Divot?

Yes. because #2 accumulator is still going down, until both arms streight. longer in front of LP longer arc. Except with zero (or fixed) #3 then balanced divot. (Scoop)

2-C-1 #3 Full Scale
Print this out and turn upside down for Players View. Average Club: Impact 4" behind Low Point.

Interesting point about #2 angle........awsome drawing there Daryl. What software do you use?

In regard to clubface implications for Separation prior to Low Point: Let me try this another way.

First read the first paragraph of 2-J-2 INSIDE OUT IMPACT. (Its a great read but for brevity Ill jump ahead to the main point.) "..........Though it is an "inside-out" Impact it is not an "inside-out" Stroke unless the Plane Line crosses the Line Of Flight as depicted in photo 10-5-E. (closed- closed).

Per 2-J-1 and 1-L-17 while the clubface is positioned in accordance with your Hinge Action at Fix (slightly open for Horizontal etc) at Separation the clubface must be square to the Target Line.

Now look at Picture 2-C-1 #3 and turn it upside down for the players perspective. Its not to scale obviously and assumes Separation at Low Point but lets imagine Separation prior to Low Point......Imagine Separation about where Impact is depicted......the clubface now square to the Target Line and THE INSIDE-OUT ANGLE OF APPROACH LIEING AHEAD OF SEPARATION.

Straight shot or draw?

AWSOME thats exactly what Im talking about.......

Its very interesting to look at this drawn to scale, thanks D. I always thought Homer avoided scale for illustrative purposes......but now Im also wondering if he did so to heighten the readers appreciation for the Inside-Out nature of Impact along the Arc of Approach. I dunno Maybe. He did say that "its inside-out and should feel inside-out".

Very fun Post.

Where did Homer say that Separation occurs at Low Point? I can't find that anywhere.

Lets agree on the Flat Left Wrist and that Both Wrists are Level at Impact. We know that the Right Wrist is Level, Bent and Vertical at Impact. Then, is the Left Wrist Vertical at Impact or at Low Point?

The Club is gripped so that the Hands align to the Longitudinal Center of the Club. That's why the Left Thumb must be on that Line (aft side of shaft). When you grip the shaft and adjust your Flat Left Wrist to Vertical, the Clubface looks shut.

I gotta run. Wife is rushing me to go for a walk in a park 30 miles from here. Go figure.

In the drawings only, 2-C-1 #3 for instance. To be clear he didnt assume it be so in a literal sense unless one positioned the ball in such a manner.

But the question makes for a different "look" than most would assume to be associated with a straight shot. Or is it a straight shot?

It has implications to grip rotation, grips with spines on them etc.

We havent even got to the Line of Compression yet!

Push with a draw for horizontal hinging push fade for angled hinging and if its possible to have verticle hinge a low push?
(I could be wrong here)
