Hey Ted

Your right, the left shoulder does moves around in its own orbit but that is moved by basically yet another another sphere with the point between the shoulders, or the stationary head as its center. My spheres analogy is basically the usage of a center point and the circles of rotation that influence it. This is exactly what Homer used, but in a slightly different way - for him it was hinge pins and swivels which influence a center point to demonstrate the same axis of rotation. For example the end point of the radius of the left arm (hand) if not restricted by anatomy or anything else could touch anywhere inside a sphere with the left shoulder as its center.

With 1-L the hinge pin is fixed to a stationary post per my 1-L and 2-K equivalent animation, however in real golf with the shoulder motions, the axis of rotation or 'the circles' of that sphere stay exactly as they where whilst being moved with the orbit of the left shoulder around the head as its stationary point which is ultimately controlled with the right shoulder. So basically the 'left shoulder is moved in the sphere' around the head (which is a moving chord from a radius inside the sphere if the head is taken as the center rather being a purely a diameter when the point between the shoulders is used) but the orientation and the circles of the sphere doesn't get influenced by its own local movement....the vertical plane dictated by the hinge action doesn't not change regardless of the shoulder moving....

All about centered arc . I know we're for sure we're not in disagreement though - just its me not explaining myself enough...lol

Ps wait until you see the new animation when I finish it, its going be wonderful .

I'll be excited to see the finished product. I'm sure it will be as good as a 330 yard drive to an island green.
