Abstract
Improved methods for manufacturing a shaft for a golf club, devices useful in such methods, and golf club shafts manufactured in accordance with such methods. A plug is detachably affixed to a distal end of a mandrel. A plurality of plies of pre-preg composite sheet are wrapped around the mandrel and plug and, thereafter, heated causing the resin comprising the various plies to be cured. The mandrel is then removed from the formed shaft, leaving the plug as an integral part of the distal tip of the shaft.
