ABSTRACT:
A composite seamless filament-wound golf club shaft and method of manufacture, in which the shaft includes a hollow steel tubular core and a filament such as steel, fiberglass, graphite, or carbon, spirally wound about the core to form a seamless jacket thereabout. The filament is impregnated with an adhesive and permanently bonded to the core, and the core may be torsionally stressed prior to and during the winding thereupon and bonding thereto of the filament. The shaft can be made as an overlong blank universal shaft, then portions of the butt and tip of the shaft can be trimmed to produce a desired shaft length and natural frequency of vibration. When attached to a club head, the head may be weighted to produce a resulting golf club of desired swing weight.
