According to Yoda, there is no center for Angled Hinging clubface motion -- end of story. Nothing about a midpoint Angled Hinge.

The essence of the situation is that with Horizontal Hinging, the Clubface is always only Closing as the Clubhead moves around its center. With Vertical Hinging, it is always only Laying Back. Hence, with Horizontal and Vertical Hinging, the two functions of the Club -- Head and Face -- can be synchronized around a single Center.

However, with Angled Hinging, the Clubface is simultaneously Closing and Laying Back. And the problem is that the Motion is not uniform. That is, there is no consistent relationship between the distance the clubhead moves forward and the degree the Clubface lays back (as it tries every split second to remain vertical to the Inclined Plane of Motion). Hence, the aggregate Motion has no center.

If all this is a bit much -- and it probably is -- just take what you can, throw the rest into your Incubator and come back later. Some things take time to 'see', and this is one of them. Homer Kelley came face-to-face with this illusive concept when he went looking for Angled Hinging's Center and couldn't find it. He ultimately solved the problem, but it took some doing. As he related to our January 1982 Masters Class:

"It has none. I had to build a model to find that out."
