Hi YODA,first up,your demonstration on the different hinges (dowels and hinge vid) top notch.

To replicate that hinging device,how many hinges would I have to use,in fact is there any chance of sketch of the unit.I understand if you are reluctant and that is fine.Thanks in anticipation

There are two hinges:

1. An ordinary door-type hinge (to control the Clubface Motion);

2. A simple 'strap' hinge, i.e., a plain metal bar connecting the 'leaf' hinge to the 'Lever Assembly' (to control the On Plane Clubshaft Motion).

In other words, this is the Dual Hinge arrangement defined in 10-10-D (Dual Horizontal Hinging) and -E (Dual Vertical Hinging). With Horizontal Hinging, the Hinge Pin is positioned vertical to the Horizontal Plane (and produces a 'Closing without Layback' motion of the Clubface). Thus, the second hinge is required to lower the Clubshaft to the Plane. With Vertical Hinging, the Hinge Pin is positioned vertical to the Vertical Plane (and produces a 'Layback without Closing' Clubface motion). Thus the second hinge is required to raise the Clubshaft to the Plane.

The Dual Hinge arrangement is not necessary to reproduce 10-10-C (Angled Hinging). That's because the Hinge Pin is positioned vertical to the Inclined Plane, thereby controlling both the Clubface (and its 'simultaneous Close and Layback' motion) and the On Plane Clubshaft.

I built my model from Homer's own drawings and specifications. Unfortunately, those plans are patented, and I am more than a little certain that I would not be given permission to publish them. I plan on pursuing this and other such matters later this year. Meanwhile, I may put up a close-up photo, and let those so inclined 'make it happen' from there.
