  • Patent number: 5513844
    Abstract: A golf club fitting apparatus and method utilizes a number of different club heads, the club heads having hosel or shaft receiving bores at different angles and securing devices for releasably securing a hosel at the lower end of a golf club shaft in the bore, and a number of different shafts. The heads have different parameters such as peripheral weighting, center of gravity, and face area in addition to different bore angles. A player can select various different head and shaft combinations to test. To test each combination, the hosel at the end of the shaft is inserted in the bore, and releasably secured in position. The player then tries it out. The shaft is released, and a new combination is tested in the same manner, until an optimum fit for that particular player is found.
