Abstract: The method of adjusting the swing-weight of a golf club by moving a weighted insert within a hollow shaft of the club, preferably in the butt end portion of the shaft, to different longitudinal positions and holding the insert releasably in each selected position. One embodiment uses a split sleeve as the insert, and expands and contracts the sleeve by a screw-operated expansion and contraction mechanism including a tool inserted through the open butt end of the shaft, the tool being releasably coupled to the sleeve to move it along the shaft in the contracted condition. A second embodiment uses a lead screw on which the insert is threaded to adjust the position of the insert along the screw, which is mounted in fixed bearings in the shaft, turned by a removable hand crank from the open butt end of the shaft, and held against inadvertent movement by friction applied by the bearings.
