Hey, stupid questions got me through college- LOL.

In fact, I was thinking about this in Canton
(Three G.O.L.F. Guys School) when Mikestloc (Mike Finney) asked me the exact same question.
Go through this
mind experiment with me and you'll understand it! It might cost you a few brain cells, but it's worth it -- trust me.
The
Vertical (Only) Hinge Action may best be represented visually by a
pendulum. Now, I know the pendulum doesn't contain any pins and hinges, and therefore it isn't a proper Hinge, but the most important thing is that their
Basic Plane of Motion are identical -- they both have a
Vertical Plane of Motion, e.g. the Wall.
- Imagine swinging this pendulum -- for example, a string with a weight attached at the bottom -- flat against the wall. Since the wall is also vertical, there should be no conflict -- the pendulum swings beautifully along the wall.
- Now imagine the weight has a Clubshaft attached to it. This Clubshaft will not be vertical with the string (although it can be), but instead, it will be at an angle, as if it's on the Inclined Plane.
- With the addition of the inclined Clubshaft in Step 2, repeat Step 1.
Nothing has changed -- you are
still using a
Vertical (Only) Hinge Action even though the Clubshaft is Inclined at an angle!
Now, if you did the step 3 with an imaginery Inclined Plane board lying flat against the Clubshaft, the Clubshaft will
not stay on this Inclined Plane while the pendulum / Vertical (Only) Hinge Action is operating. If you wanted the Clubshaft to stay on this Inclined Plane, you would need to use a
Dual Vertical Hinge Action, which is
not what we're talking about here.
So to summarise:
- Contrary to popular belief, the Clubshaft/Sweetspot angle of inclination does not have to be vertical when using Vertical (Only) Hinge Action. It can be inclined at any angle you want.
- The Clubshaft never stays 'On Plane' when using Vertical (Only) Hinge Action. The only exception is when the Clubshaft is also Vertical.
