Abstract
An apparatus for selectively adding weight to the hollow shaft of a hand-held implement. One embodiment includes a deformable upper cylindrical member, a lower member, and a rod coupled between the upper and lower members. These components are sized to fit within a hollow shaft, such as a golf club shaft. The upper deformable cylinder includes a chamber at its upper end, into which an oversized insert is inserted. This causes the deformable cylinder to expand radially creating a friction fit with the inside surface of the hollow shaft. The lower member may include an annular deformable member, such as an o-ring or a sleeve, stretched over its outside surface to create a snug fit within the shaft.
