In a 1981 GSEM Class discussion, Homer Kelley referred to two types of Clubshaft Bend for Swingers. The first -- "Acceleration Bend" -- stresses the top of the Shaft during the Start Down. During the second -- "Release Bend" -- the stress is opposite the Acceleration Bend as the toe of the Club attempts to get in line with the #3 Pressure Point.
The Hitter's stress is at the back of the Shaft and does not vary.
Thanks Lynn! Great addition to this thread!
Just for my curiosity can you or someone else reference where he says the "wallop of centrifugal force" in the book- I believe it's there but am blanking out where to look.
Actually, never mind- I found it in 6-F-1 "Right" Timing...."Acceleration ceases when the speed it has produced equals that of the Thrust, and though the thrust is still present and able to maintain Velocity, it loses the flexed, stressed Clubshaft (Hitters) and the wallop of the Centrifugal Force (Swingers)."
