What’s vertical hinge action? From impact to follow-through, both arms
straight, clubhead still below the hands and pointing at the plane line by
definition of on-plane, purposefully reverse swivel the left forearm and flat
left wrist to face the sky, squarely. You could set a glass of water on that
clubface. A bit awkward, takes some practice to get it vertical, but extremely
useful at times. Very short clubhead travel to both-arms-straight. Gotta
sustain the lag. Good practice. IMO, superior to setting up wide-open which
brings direction problems into play. This way is square and straight, normal
setup, high trajectory, soft landing, straight roll, maybe a little bit of stuff on
it but not much.
Probably go right under a ball in fluffy lie. I’ve done that with a wrist flip as a
naive tyro. (Novice. Just wanted to use that word once in my life. I’m an Okie,
different language. Joshing. We say “tenderfoot” which describes calves or
foals, havin’ no truck with sheep.)
What’s angled hinge action? Feel “no roll”, results in about a half-roll of the
clubface to follow-through, both-arms-straight as defined above. Short
clubhead travel. The default hinge action for the hitter due to the physics of
right arm drive-out. Technically speaking the flat left wrist remains
perpendicular to the inclined plane from impact to follow-through. No wrist
“swiveling”, and the same inclination in the backswing until the right arm
folding forces it to go on plane will produce the same “no roll feel” in the
backswing for consistency.
Horizontal hinge action feels like a full roll and produces a full roll,
although no actual hand motion occurs. It’s just like a door closing. The
door didn’t roll or twist, but it closed, at a precise and consistent rate. The
flat left wrist remains consistently perpendicular to the ground, i.e. the
horizontal plane. HH has the longest clubhead travel to follow-through. The
default for a swinger not working the ball. Length of clubhead travel to
follow-through, both arms straight is the Rhythm of the stroke.
That’s my story and I’m stickin’ to it. More contributions?

LOREN HINGE ACTION
This’ll blow you away, or fire a lightbulb. There is no actual motion.
Hinge Action is merely keeping the flat left wrist perpendicular to one of the
three basic planes, the ground, the inclined plane, or the rear wall of the
virtual box you’re standing in, from impact to follow-through. Horizontal,
Angled or Vertical.
The centrifugal force managed by the swinger will automatically produce
Horizontal hinging because of the sweet spot’s inertia. The hosel rotates
around the sweet spot, not vice versa. The wrist stays perpendicular to the
ground.
Raise the club up and move it around 180 degrees flat-footed with no wrist
turn or roll. The clubface relative to the target line opens and closes, just
like a door.
Put another pin in that shoulder hinge that will allow the left arm (hand) to
drop down to the inclined plane and do the same thing. It feels like a full
roll, but you didn’t roll it. Yet the clubface did a full roll, or “closing only”
motion.
The drive-out action of the hitter’s driving right arm automatically produces
Angle hinging by virtue of its thrust direction, and no sweet spot inertia. The
left wrist stays perpendicular to the inclined plane. If feels like no roll and it
produces sort of a half roll of the clubface. It’s a “closing with layback” in
Homer’s vernacular. There is no secondary pin in the angled hinge, or “dual”
action pins. It’s pin is already oriented for the hinge to work on the angle of
the inclined plane.
The swinger using Angle hinging merely feels “no roll” to keep the left wrist
perpendicular to the inclined plane. It’s a “hold off”. If you’re managing
trajectory, you need Angle hinging.
Manipulated hands.
The hitter trying to do Horizontal hinging will have to manipulate it for a full
roll “feel”. It’s a bit awkward feeling but can be done all right.
These things you practice in Basic Motion, two feet back, two feet through,
hitting and/or swinging, pivotless, with/without a club or dowel, closed fist
and open hand, and finally with eyes closed.
Either will have to actually swivel the left arm to keep the left wrist
perpendicular to the wall behind them which feels like a reverse roll.
You have to plan ahead for this no later than Top. “DELIVERY LINE ROLL
PREP” (in all caps), item 22 of 12-3-0, (ref. 4-D-0 and 7-14).
A putter using the rock-the-shoulders, frozen wrists stroke (Tiger) with
swing center in the sternum is using Vertical hinge action. Accurate but not
powerful. Long putts on non-tour speed greens will have a little “short”
problem.
A putter using a “push basic” stroke (Phil) is using Angle hinging but could
use Horizontal for distance or vertical with manipulation.
BUCKET HINGE ACTION
So horizontal hinging would be holding your left wrist vertical to the ground
while you move your arm back and forth like a door to your house or a
helicopter
vertical hinging would be holding your wrist vertical (90 degrees) to a
vertical plane . . . your arm would move like an attic door . . .
angled hinging would be holding your wrist vertical to the inclined plane . . .
like a paddle or one of them bomb shelter doors.
So the hinge pin . . .which is in your shoulder is mounted VERTICAL . . 90
degrees . . . to the plane of motion . . . but with vertical and horizontal
hinges you have to have ANOTHER HINGE to lay the motion ON THE
INCLINED PLANE . . that's why you have DUAL HORIZONTAL AND DUAL
VERTICAL . . . dual representing two hinges . . . one hinge perpendicular to
the associated plane (horizontal plane or vertical plane) and the other hinge
to lay the blade of the hinge (left arm) on the INCLINED PLANE . . . See the
pictures 10-10-C thru E . . . you'll see what I'm talking about . . . you DON'T
need the second hinge to lay it on the plane with angled so you don't have
"dual" angle . . .no need for the second hinge because the motion is already
on the inclined plane.
Hinging is actually with the WHOLE ARM . . that is the full blade of the hinge
. . .Homer just focused on the wrist because it could be verified in terms of
what it was vertical (90 degrees) to . . . (ground, wall, inclined plane) . . .
you'll note in the 10-10-C thru E pics the two theoretical hinges in the left
shoulder . . . one is like a door hinge the other is like a lose nut and bolt that
allows the blade of the hinge (left arm) to be laid on the plane.
but to answer your question . . . vertical is vertical to the ground with
horizontal . . but 90 degrees to a wall with vertical hinging and 90 degrees
to the golf plane (roof) with angled hinging . . .
