With his words "precisely between the feet," I believe Homer was talking about a face-on view, not down-the-line. The Waist Bend locates the Head outside the vertical plane of the Feet. The hinge pin through the Head to the ground would establish the "three supporting points" you mention.

My own 'Isoceles Triangle' concept uses the triangle as the geometric figure describing the relationship of the centered Head to the Feet. It is not a graphic representation of the Tripod itself.

If I am visualizing this correctly, the hinge pin throug the head, nah, I am not.

What I was visualizing was the the hinge pin from the head down through the spine. This can't be cause the hip motion (shifting and possible turning) would move that line, saying it started in the center, it certainly would be their at impact.

Maybe the Hogan concept is more accurate and in line with what Homer was leaning too. After all Hogan didn't say it had to support weight, merely make contact with the ground.

I think the last statement is important because I gathered a number of readers were seeing the triangle as the tripod. A sidenote, one of the pictures in one of the thread on this topic that was using the triangle, failed to take into account the slope or camera angle and cause the apex of the triangle to be placed outside the head. I am still working through this with the triangle and effect the stance width has on it with regards to its relationship to the ball position. Also this would seem to define a limit or a check point for when the hip slide goes beyond a certain point as it would move the apex cause of the shortening of the right side and axis tilt.

Still very rough..

So the visualization I should have would be
a. A line from the left foot/leg to the base of the skull
b. A line from the right foot/leg to the base of the skull
c. A line from the base of the skull ???? (This is the hinge, it rotates around the spine, so does it follow the spine?)

Sorry for being so dense on this and a pain...

L1, L2 or L3(The Hogan Concept)? or should I toss this and start all over again in search of the third leg?
