Abstract:
A method of producing a conventional golf club including a grip with a grip end and a butt end, a shaft, and a club head having a center of percussion, wherein the golf club is considered to be a pendulum with a pivot point defined by a position slightly below the point at which hands of a golfer are positioned upon the grip when swinging the golf club, the method comprising the following steps:(a) selecting a swing weight, wherein the swing weight is defined by the equation:swing weight=W(L-12)where:L=a distance from the butt end of the club to a center of mass for the entire golf club.W=the mass of the entire golf club.(b) defining the pivot point according to hand placement of a golfer;(c) defining a moment at the center of mass to be substantially equal to a moment at the center of percussion in accordance with the following equation:l.sub.c m.sub.c =l.sub.h2 m.sub.hwhere:l.sub.c =length from the pivot point to the center of mass,m.sub.c =mass at the center of mass, andl.sub.h2 =length from the pivot point to the center of percussion, andm.sub.h =mass of head.
