Abstract
A a method of making set of a plurality of at least a combination of three golf clubs of progressive lofts that are matched to provide identical swing characteristics; each of the golf clubs including a club head, a shaft and a grip at the upper end of said shaft; each club of the combination characterized by having an essentially identically located, computer designed center of gravity; each club being further defined by the shaft having an equal length, having an identical swing weight, identical grip weight and an identical club head weight.
Claims33
A method of making a set of matched golf clubs in combinations of at least three matched golf clubs;
- each club having a club head, a shaft and grip to provide identical swing characteristics;
- said club head having a means for connection to a shaft, a frontal ball striking face, a top surface, bottom surface, heel, toe and rear surface defining a rear weight and cavity formed therein, comprising the steps of:
- a. locating the center of gravity of each of the club heads of a given combination of club heads of the set in the same relative position in three axes in each club head defined by the intersection of the horizontal X-axis, the vertical Y-axis and the posterior Z-axis;
- b. matching the weight of each of said club heads whereby the weight of each club head is the same;
- c. matching the length of the shaft of each club whereby the length of each shaft is the same;
- d. and, attaching said shaft with a grip to said club head whereby each club has an identical length, identical weight, identical swing weight and identical center of gravity location.

- said club head having a means for connection to a shaft, a frontal ball striking face, a top surface, bottom surface, heel, toe and rear surface defining a rear weight and cavity formed therein, comprising the steps of:
- a. locating the center of gravity of each of the club heads of a given combination of club heads of the set in the same relative position to and equidistant from the frontal ball striking face in three axes in each club head, the axes defined by the intersection of the horizontal X-axis, the vertical Y-axis and the posterior Z-axis,
- b. matching the weight of each of said club heads whereby the weight of each club head is the same;
- c. matching the length of the shaft of each club in the combination whereby the length of each club is the same;
- d. and, attaching said shaft to said club head whereby each club has an identical length, identical weight, identical swing weight and identical center of gravity location.

- a. locating the center of gravity of each of the club heads of a given combination of club heads of the set using a computer aided design program in the same relative position to and equidistant from the frontal ball striking face in three axes in each club head, the axes defined by the intersection of the horizontal X-axis, the vertical Y-axis and the posterior Z-axis,
- b. matching the weight of each of said club heads whereby the weight of each club head is the same;
