ABSTRACT:
A method for relocating the center of percussion of an assembled golf club such that it substantially coincides with the center of the club head face, the present method taking into account the weight of the particular club shaft and grip affixed to the club head, the center of gravity of the club head both before and after the club shaft and grip are affixed thereto, and the offset relationship between the center of percussion of the assembled club and the center of the club head face. In its simplest form, the present method includes determining the center of percussion location on the club head face of the assembled club, comparing such location to the center of the club head face, and thereafter specifically weighing such club head so as to move the center of percussion of the assembled club from its previous offset position to substantially the center of the club head face. The present method is also advantageous in redesigning and manufacturing new club heads in that the resultant weight distribution pattern achieved for a particular club head establishes a new center of gravity location for such club head and this new weight distribution pattern and new center of gravity location can be replicated in a new club head design. Although the present method is centered around relocating the center of percussion of an assembled golf club to the center of the club head face, it is also ideally suited for relocating the center of percussion of an assembled golf club so as to either fall within an acceptable zone around the center of the club head face, or coincide with a location on the club head face where a golfer consistently makes contact with a golf ball.
