The Flat Left Wrist "represents" the Clubface and then only does so if the Primary Lever travels at the same RPM through the Impact Interval.

I think "make the motion" in this case with the "generic" flat left hand/wrist and the clubface will take care of itself.

The Left Arm is a Lever. The Hinge is at one end of the Lever. The Left Shoulder is at the End of the Lever. The Hinge Pins are Located at the Left Shoulder.

I kind-of stuck it in the arm because there are some rotary alignments to maintain.

The Path of an orbit is three dimensional. The Orbit can exist on a two dimensional Plane. Hinge Action and keeping the peas on a spoon are two different vegetables.

What off plane forces/motion do you have in mind that will make the third, off plane, dimension?

............ Now that you mention it- I like peas
