Abstract:
A method of making a light weight golf club for reducing the overall weight of the golf club while providing a swingweight similar to that of a typical steel shafted golf club, the method comprising the steps of:(a) forming a plurality of weighting plugs of different weight by combining different amounts of a dense weighting material with a moldable resin to form differently weighted combinations and curing the differently weighted combinations in a suitable mold; (b) forming a light weight golf shaft by: (1) providing a mandrel; (2) selecting a weighting plug from the plurality of weighting plugs of different weight; (3) removably attaching the selected weighting plug to a tip end of the mandrel; (4) forming the golf shaft by rolling thin layers of prepreg composite materials onto the mandrel and weighting plug in a predetermined order; (5) hardening and curing the golf shaft by heating, the plug and golf shaft being formed into a one piece composite member; and (6) removing the golf shaft and associated plug from the mandrel; and (c) attaching a golf head to the golf shaft.
