From the "camera setup" thread:

Here's something I drew a while back with another intention in mind. For this discussion (how to shape your shots) lets just acknowledge how the circle looks different from different perspectives. How the players view of the circle becomes more circular as the plane angle lowers.

Edit : And also acknowledge how the actual path of the clubhead along its circular orbit has more OUT to it for flatter plane angles.

Guys feel free to correct this where it needs to be corrected. Blunders or whatever. The curves are hand drawn and need to be improved for starters.

Nice . There's a thread around here somewhere where Luke is talking about how almost impossible it is see where a players plane line really is pointing when looking at videos in a conventional manner. Most guys assume the stance line to be an indicator etc ... That just doesnt cut it. Luke then traced the clubhead path with little dots , we were looking down the line of course, and you could see the direction the club head was travelling in a lot better. Not as good as radar or anything but way better than trying to find a plane line when looking at a golfer through the vagaries of a camera lens. The nature of the lens changes things a lot too. Parallel lines start to look more divergent as you go to lens which are wider than what the human eye sees etc . I think . Any camera men out there? What the human eye said to be similar to 50 mm film lens? Film lenses being different than video maybe? I dunno.

Dang good. Thanks.

Er, wait ... should it read "2 dimensional inclined plane" ? My head hurts.


From the 7th I believe

Couple of Homerian terms to go then we can hit some draw shots .

Anyone wanna tackle what Homer meant by Grip Rotation? We're gonna need it.

I think 7-2 said it, in words, about as well as possible. Note-only hitters rotate their grip- TURN THE HANDS TO A NEW POSITION ON THE GRIP. It must be assumked that the hitter is using angled hinge and the swinger4 is using horizontal hinge.
If the ball is moved back , the hitter will hood the clubface to maintain a square leading edge, a draw will result, and if the ball is moved forward the hitter will lay back the clubface to square the leading edge. and a fade i s result. rotate the grip to do this.
The swinger , with horizontal hinge, when the ball moves back it opens the clubface3. Just rotate the plane line to conform to clubface alignment an fade. move ball forward, rotate the plane line to match the leading edge and a draw will result.
Do not move your stance in hitting procedure. the hitter can take a normal address , move the ball back/forward then rotate their grip. The swinger can take normal stance, then open or close their stance which will have the same effect as moving the ball back/forward and will accomplish the plane line rotation at same time.The swinger does move

Nice .

Isnt it more correctly Hitters and Hand Manipulated Swingers ? Meaning just about everybody except the True Swinger ... those for whom CF [U]alone[/u] squares the clubface by definition?

The answer to this question doesnt matter in regard to the geometry at hand .... if when you position your ball "back in your stance" which we now see as being BACK , IN , UP (thank you D) along the golfers view of the circle , THE ARC OF APPROACH you also rotate the face square to the Target Line , Impact Plane Line you have effected GRIP ROTATION according to Homerian definition. (interject please anyone who wants to redefine). Draw shot resulting but in accordance to the amount of OUT associated with path of the clubhead ..... the distance between the IMpact Plane Line and the Low Point Plane Line on the Basic Horizontal Plane given plane angle. And loft etc.

Still talking theoretically here looking at the circle diagrams.

This may seem weird . What about grip spines aligned at 6:00 o'clock on the shaft wouldnt grip rotation move these spines counter clockwise in the hands ? (yes) And is a six iron really designed to be played at Low Point? Homer said no! Enter Hook Face , enter confusion and differences of opinion perhaps ... tbd. I see two schools of thought , perhaps both co existing ... Maybe we dont need to go there ? We could just stick to DIVERGENCE BETWEEN FACE ANGLE AND PATH . Thats the basic basic to common speak "side spin". Uhhh Homer never said "side spin" he referred to it as "tilted backspin" (no caps) .... the ball can only spin around one axis I believe.

Closing in on draw shot tendencies for balls played back in the stance and a sketch there of from the players unique perspective and in accordance to plane angle considerations. A useful visual for the golfer in shot shape training.

I hope that you're keeping in mind that any distance the ball is played aft of Low Point, that a corresponding steepness in Swing Plane must be applied to hit a straight shot.

Ok that would imply a steepening to the clubs lie angle wouldnt it ? A toe down deal ? Why cant you just maintain lie angle ? Hmmm are you talking about the IN of Back , In , Up ? If thats what it is I see it , yes. Interesting.
