  • Patent number: 4203598
    Abstract: An improved method of determining the true swing weight of a golf club is provided by balancing the club at a fulcrum located under the shaft at a point approximately five inches from the tip of the grip end of the shaft. All of the golf clubs in a set are matched to each other on the basis of (a) total club weight; (b) the location of the club's center of gravity at a point on the shaft which is a constant distance from the tip of the grip end of each club; (c) true swing weight. This matching is accomplished while accounting for the effects of an additional component weight placed in the grip end of the shaft, displaced radially from the shaft axis. This additional component weight also produces a countering force to the torquing forces which act to resist the golfer's efforts to bring the club face into proper alignment for impact during the latter part of the downswing. This additional component weight also tends to counter the precessional forces on the head which develop during the swinging of the club.
