Clubshaft orbit through the impact zone

jeez, all this so you can go back to ISG and shout "you're wrong" at people.

I presume that we agree that the clubhead never travels in a straight line and that its path is always circular.

Here is a tracing of Kevin Na's clubhead arc through the impact zone.



Although the clubhead arc is circular as the golfer traces a SPL, the clubshaft lies against the surface of the inclined plane as it travels through the impact zone - as seen from a DTL view. In that sense, the clubshaft must stay on-plane against the surface of the selected inclined plane (eg. elbow plane) during its passage through the impact zone.

Styles- you are wrong. I have been barred from posting at ISG.

This "Golf for Jeff" forum allows any LBG forum member to post their opinions regarding golf mechanics/biomechanics/geometry/physics without fear of censorship - in contrast to ISG which doesn't allow contrary minority opinions that are unpopular. I will only censor comments that are overt ad hominem attacks. There will no flame wars in this forum as long as I am moderator. You, or any other LBG member, are fully entitled to prove me (or another forum member) wrong on any golf swing issue as long as the post doesn't contain unnecessary ad hominem insults. In fact, very vigorous debate is highly encouraged in this forum as long as the poster doesn't indulge in non-decorous behavior that degrades the "quality" of this LBG forum.
