Swivel = Independent rotation of the Wrist and Forearm BM#201

From what I know... and looking at 4-O... there appears to be only reference
to these movements based on hand motion only. This does not account for arm
participation. Yet quite clearly 4-C is only possible with a rotation of
either the forearm or the whole arm.
To me I would think a distiction between forearm rotation and entire arm
rotation would be a rather important subject to discuss when we look toward
what parts of the body are being effected by each stroke pattern.
As I've stated repeatedly in numerous posts, there is no true Rotation (of
the Left Wrist, Arm or anything else) in the Hinge Action. The Flat Left
Wrist -- and you can throw in the rest of the Arm if you want to -- remains
Vertical to the selected Plane of Motion. Only in the Swivel is there
a true, independent Rotation of the Wrist and Forearm.
When in your stance with an angled spine, is the pin for horizontal hinging
parallel to your spine - so the horizontal hinging is relative to the
inclination of the body - or, is the pin perpendicular to the ground or
horizon?
I have been working with the frame of reference being my posture inclination
so the horizontal hinging motion is parallel to an inclined plane.
Help me understand this.
The pin is perpendicular to the horizontal plane, e.g., the Ground. The Hinge
Action concept is totally independent of Spine Angle.
No Relationship between Hinging and the spine BM#205

she assumed her stance and tilted forward at the hips. However, if the pin is
to remain perpendicular to the ground even when the address posture is taken,
the hinge pin shown in the picture would no longer be parallel to the spine
and would rotate to an oblique angle to the spine, in order to remain
perpendicular to the ground, as the model assumed her posture (picture not in
TGM). I can't get my mind around that.
Tough to imagine swinging around a pin vertical to the ground at a ball at
your feet and a hinge at your shoulder.
Sorry, just tough to get the image.
Again, the perpendicular positioning of the Hinge Pin to one of the three
Basic Planes of Motion is completely independent of any spine angle or body
posture. If, as you suggest, the model bends over more, the Pin doesn't
'bend' with her. It remains perpendicular to the horizontal plane. If it
helps, you might want to pretend like she had an operation and had her old
posture Hinge Pin removed and reinserted into the new.
When is vertical hinging being used? Putting (Pelz/PILS), chipping, cuts?
Due to its Power limitations, Vertical Hinging is best used only in the Short
Shots.
Homer Kelley was no fan of Vertical Hinging. He thought it was important to
learn in order to be able to differentiate the three Hinge Actions, but on
the Golf Course, he strongly preferred Angled Hinging. The reason was that,
on the steep Plane of the shorter Shots, Angled Hinging approaches the
Layback Only characteristic of Vertical Hinging. However, it does so without
the deliberate mechanical manipulation -- the 'Reverse Roll' Feel -- that is
always required for Vertical Hinging.
