Guys the geometry you are discussing warrants a new thread. A thread Ive been waiting for a long time. Hook face, low point vs straight away point, true swinging vs manipulated hands, plane rotation vs grip rotation etc etc its all in the geometry of the circle and can be drawn with pencil and paper.

It could be a little contentious given the similar studies popular today. Launch monitor , trackman, d plane etc. I think there's probably some points of departure , not sure where but Im sure there is. Homer came at it from a geometry perspective, geometry of the circle. Paper and pencil and deduction. Its not the only way today but it was in his time.

Is the circle irrelevant because the clubhead path is really elliptical? No. Its a model that is relevant and further more the point of impact is also a point along the ellipse's circumference where the radius, the left arm and the club (the primary lever) is nearing full extension , making it very circular in form. Fixed center , fixed length of radius giving you a circle. The relevancy of the circle assumption increases as impact nears. You could refine the geometry to show the ellipse and plane shifts unique to each golfer but you dont need to do this to convey a basic understanding of the geometry at hand. The basic understanding necessary to influence a golfer's Intentions. The antithesis of Homers Steering. Namely , the geometry of a Hinge Action of an Angular Motion on an Inclined Plane. Golfs geometry ......hockeys too, field hockey... etc. The instrument employed dictating the geometry. Sam Snead's old croquet putter would imply a change of geometry to non inclined plane.

Start a new thread.

By the way I agree that the amount of hook face is determined by the manufacturer unless you have bent more hook face in or out yourself. You can of course add further grip rotation and effect more of a hooked face and deloft the club........ We need to stick to definitions to discuss this one, I suspect you're both saying the same thing in different ways. The hockey stick thing alone doesnt mandate a hooked face, my driver has a slice face for instance as its designed to sit square fore of low point.

A discussion on Hook face by itself , let alone the entire Geometry would take a few pages. This will be big , but its time has come. Wonder if Yoda will jump in?

Nah. He can follow his own path like so many others. It'll be a longer journey than necessary. Been there.....done that.
