With Homers drive loading basic pattern will I be tracing the true Plane Line 10-5-A with the #3 pp (arc of approach), unlike the angle of approach with the 10-5-E Plane Line. Why is the angle of approach preferred over the arc of approach for the hitter. Also is the hip slide still parallel to the plane line for the hitter with the arc of approach.
Thanks O.B for fishing those posts up. From them I have picked up that yes I can trace the true geometric plane line but still not sure on the hip slide, should it be parallel if I trace the true geometric plane line or cross line?
Is video available which demonstrates these points?
IMO 3D animation is really needed to show this geometry as the camera or point of view needs to move around to see the topic at hand. Luke posted some very nice screen grabs on another post called something like "Delivery Lines...what are you lookin at".
Homer must have done a lot of perspective drawings to figure this all out in his garage fifty years ago. I imagine him running between his plane board and his drafting table. I see him surrounded by contraptions and drawings moving a mirror around his plane board so he can see what going on from dtl, in front, maybe even overhead.
Anybody got any pictures of the inside of Mr Kelley's garage from the old days? His methods of discovery could be our methods of understanding. He did recommend we climb inside a plane board, I believe.

Cheers!
Im not sure if a hitter should trace the true geometric plane. I dunno. But I think I remember Luke saying he sometimes did. This is such a confusing subject! I know Yoda recommended the swinger stay away from the straight line , covering of the angle of approach.
In regard to your last question, as Yoda stated "Per 7-12, all motions---Pivot and Power Package---move parallel to the selected Delivery Line". So I take that to mean that you should slide your hips (with the hip held back, but just enough to shift your weight left , no more, dont exaggerate,) down the target line OR the angle of approach depending on your preferred Delivery Line of the clubhead (and right arm for hitters).
Can I add some questions?
-Why/how is the plane steeper when using the angle of approach?
-Why does the hitter use/cover the Angle of Approach anyways? Something to do with the right elbow or thrust I bet. Direction of thrust.
-Does the Aiming Point for the person using the Angle of Approach move outside the true geometric plane or target line then?
-Why is the Angle of Approach method "uncentered". What does this mean? Has the Hitter lost the left shoulder as his swings center?
Basically it boils down to rotation, plane and pressure point location.
A swinger, with startup swivel, can stay 'on line' and on plane. You can't really stay on plane/on line unless you let the #3 pressure point rotate. A swinger is supporting 'under' the shaft.
A hitter doesn't (usually) allow #3 to rotate - no startup swivel - and is supporting the side of the shaft/arm/club - the entire primary lever.
In order to provide that support to the side of the shaft and still stay on plane, the hitter needs to push 'cross line' and thus usually a hitter uses angle of approach.

Edz, great reply, when you say the hitter needs to push cross line to stay on plane, is this with a closed plane line? If so does the hitter still push cross line with a square plane line?
Ally - with any plane line really. The push is relative to the plane, not the ball-target line.
So open/square/closed to the target line, a hitter is pushing more 'out' and swinger is pulling more 'along' relative to the straight plane line.
Now keep in mind that it is only pushing vs. pulling that separate hit vs. swing in the final analysis, so it is possible, although not advisable to mix components around, but it would be fighting the laws of physics!
Think of kicking a football/soccer ball.
The swinger, with an on-line delivery, is kicking more directly 'down the line' - more of a front/top of the foot kick. (but importantly, still from the inside)
The hitter, with an angle of approach, is kicking more from 'inside out' - more of a side of the foot kick.
Because we stand to the side of the ball, both swingers and hitters are always moving down, out, and forward. The hitter's lack of rotation of PP#3 means they have a touch more 'out' in order to support impact with the right forearm, just like the side on football kicker.
