Basic Planes??

(in the process of typing this I *got it* )

(SO, I'll do a 180)

*AHEM*....

.......

oooooooooo! I get it!......

......

Vertical to the Horizontal Plane = through Impact to Follow-Through keep Left Wrist Vertical to a hoola-hoop around your waist.

Vertical to the Angled Plane = through Impact to Follow-Through keep Left Wrist Vertical to an Inclined Plane (i.e. pane of glass resting on your shoulders- right?)....

Vertical to the Vertical Plane = through Impact to Follow-Through keep Left Wrist Vertical to a windmill's "fan."

Cool.....can't believe it has taken me a year and a bit for this "egg to hatch"...she was partway cracked open but she just split in half.

Thanks Leo.

Thanks Paul, the ecstacy of egg smashing is what keeps me posting. Bam! Crack! Another egg smashed. Next!

Lets really finish this off.

I like to image a flat tabletop to represent the Horizontal Plane of Horizontal Hinging.
Do this:
Have your Left Arm straight in front of you, with a Flat and Vertical Left Wrist, and your whole arm resting on a (imaginary) tabletop.
Now have move the whole of your Left Arm about a feet to the right (towards your right shoulder) without moving your body. Your Left Wrist should still Vertical to the tabletop.
Now drop the whole of your Left Arm onto the golfer's Inclined Plane, without doing anything with your Wrists.
Notice that it looks as if it's turned relative to the Plane Line. However, it is still Vertical to its associated Basic Plane (Horizontal Plane).
That's the exact alignment of your Left Wrist at Impact.

Also notice that this Vertical Left Wrist alignment looks more open/turned compared to the Hitter's Left Wrist. This is because the Hitter's Left Wrist is Vertical (perpendicular) not to the Horizontal (tabletop) Plane, but to the Inclined Plane.
But even though the Swinger's (using Horizontal Hinging) Left Wrist condition looks slightly different than the Hitter's (using Angled Hinging) Left Wrist condition, they are both Vertical! Vertical to what? That's right!
