Abstract
An annular or porous insert of predetermined weight is mounted at a predetermined location within a tubular golf shaft, the shaft being of any suitable material including either metal or graphite. The insert is circumferentially uniform and is dimensioned so that it does not of itself have an impact on the swing characteristics of the shaft, other than the swingweight and/or the total weight of the manufactured shaft. In this way the swingweight and/or the total weight of the shaft can be altered without having to change the construction of the shaft. Furthermore the insert is simple to install at any desired location and it does not interfere with the assembly of the finish club, nor does it violate the standards of the USGA.
