Tracing a Straight Plane Line after impact
On any normal shot, the clubhead is traveling DOWN PLANE toward the ball prior to impact. When the clubhead is traveling DOWN PLANE it is moving—relative to the target, plane and low point lines (more on that in a second)—DOWNWARD toward the ground, OUTWARD toward those lines, and FORWARD closer to the target.
When the clubhead hits the ball on a normal shot, it is STILL MOVING DOWNPLANE i.e. DOWNWARD toward the ground, OUTWARD toward those lines, and FORWARD closer to the target.
It contacts the ball VERY SLIGHTLY on the ball's INSIDE-AFT QUADRANT, with the CLUBFACE also very slightly open. While the clubhead is in contact with the ball, the clubhead moves about 3/4th of an inch FURTHER DOWN PLANE.
The CLUBFACE then "squares up" and the ball is gone straight at the target.
The clubhead is STILL TRAVELING DOWNPLANE WHEN THE SEPARATES FROM THE "SQUARED UP" CLUBFACE!!! This occurs on what we call the "target line."
The clubhead is moving toward LOW POINT, which is simply the BOTTOM of the swing, the LOWEST POINT the clubhead reaches relative to the ground.
The point where the clubhead reaches the ground is the PLANE LINE, simply the line where the "Swing Plane" intersects with the ground.
AT THIS POINT THE CLUBHEAD IS STILL GOING DOWNPLANE i.e. DOWNWARD toward the ground, OUTWARD toward those lines, and FORWARD closer to the target. It is also TEARING UP THE EARTH, making the first part of a DIVOT.
When the clubhead reaches its LOWest POINT—at the bottom of the divot—it is now "on" the LOW POINT PLANE LINE, which is below the surface of the ground.
So to review we have the TARGET LINE that the clubhead reaches first when the ball SEPARATES from the clubhead, the PLANE LINE where the clubhead reaches the GROUND, and the LOW POINT PLANE LINE where the club reaches the bottome of the divot. Each successive line is slightly further away from the golfer, becuase....
WHEN THE CLUBHEAD IS MOVING DOWNPLANE it is moving DOWNWARD toward the ground, OUTWARD toward those lines, and FORWARD closer to the target.
When the clubhead reaches LOW POINT, it BEGINS TO MOVE UP PLANE, which is UPWARD toward the sky, INWARD toward the golfer, and at this point also FORWARD toward the target.
Whew!
As the clubhead moves up plane, it is SWINGING LEFT OF THE LOW POINT LINE, then LEFT OF THE PLANE LINE and then LEFT OF THE TARGET LINE.
I'm sure I missed something because I am very tired from teaching VERY WELL all day, as I fix 'em all, and several with the underlined—poorly "debated" truth of the geometry of the PLANE.

Another good post Brian!
An interesting point here in Brian's explanation is that the ball as left the clubface BEFORE the clubhead touches the ground.
Notice that this is DIFFERENT to the diagramatic explanation given in 2-C-1, where the ball SEPARATES at LOW POINT.

Thanks Leo.
The ball MIGHT separate at low point. But most of the time it doesn't.
There was a great picture in some book of impact before the clubhead hit a hard surface—like a lie board.

Effect of adding right arm!
What happens as you add more right arm thrust through impact?
Will the clubhead tend to travel OUT more, even AFTER low point? So, as the clubhead is going UP and FORWARD after low point (by definition), it keeps going straight or to the RIGHT of low point plane line.
Discuss!!!

Leo:
I'll let Brian answer but I think this is one of the feels vs. real. When people add right arm thrust or try to 'extend' down the 'plane line', the feeling is that it may be going more out...however, my gut tells me that although you may feel as there is more out, unless the center of your circle moves, it is only a feelling and the club does stop moving out and continues back up and inward on plane....

Clubhead "walk" off the plane all the time. Most of the time because of STEERING.
The "theory" that an extra bit of right arm, would throw the clubhead out of orbit, needs to be discussed by the likes of Mandrin, Grober & Zick.
I hope to see at least one of them at MIT, and I will ask if the un-proven theory is a actual possibility.
My empirical data says that TRYING to do this, causes golfers to swing WAY, WAY, WAY too much to the right.

Brian,
Thansk for the thorough answer, very helpful. I never really understood down out forward til now. Didn't really know where I was doirecting the DOF force.
A clarification if you don't mind:
You state; " LEFT OF THE LOW POINT LINE, then LEFT OF THE PLANE LINE and then LEFT OF THE TARGET LINE."
I assume Low Point Line, Plane Line, and target line are really all on the same line, just differnt points along that line, correct? There are not multiple lines.

Why? I can kinda "see why"......can't really put it into words tho.
I see Tiger....
...
BTW I guess the clip of Tom Bartlett demonstrates that you can do it on-plane??

I can trace a SPL in my backswing pretty easily, but have trouble on the downswing. I have a few tendencies - swing too far to the right, come over with an open clubface, and I am sure there may be other things I do as well.
My question is this: in order to better trace it thru/after impact would it be ok to picture a line from the ball forward (target line) and try and direct my swing to and/or down that line from the top?

Low Point Plane Line.
Plane Line.
Target Line.
They are all different lines all parallel to each other.

Might need a diagram for that one!

If the plane is a flat inclined surface - like the pitched roof - then low point plane line is the gutter ( where the rain collects), the target line is the line of the first row of tiles( where the rain is just before it flows into gutter)... the lines are parallel but they both lie on the same angled plane.
I think

You are correct.
but they are SOoooooooooooooo close together you wouldn't believe.

Yep, i agree, Boss... The amount of left that my hands needed to go was first shown to me when i stood inside a plane board ( full circle like Homer's) and suddenly realised that hands went long way left ( and felt closer to my body than ever before in this section of swing) but clubhead went down plane and shaft stayed on plane.... of course "long way left" was a feel for a lifetime steerer.... the mechanics did not lie...straight plane line post impact may feel very different dependent upon where you were before...

Brian,
I know you are in my home town right now at a seminar, but if you are searching for a topic for the next installment oF BM on Youtube, I would love to hear and see you discuss this topic, esp. what Bulldog talks about above becuase I think there is a lot of confusion about what should be happening into, thru and post impact.
