Abstract
A golf club and a primarily non-metallic golf shaft that has an overall light weight are provided. The shaft has a weighting plug located to provide a swingweight similar to a typical steel shafted golf club. A method of making the golf club and golf shaft is simple and efficient, and centers the plug in the golf shaft. The method also provides the advantage of substantially infinitely variable plug density selection within a range of densities. A set of clubs thus made increases playability by providing a range of club weights in the set.
