Abstract: An embodiment of this golf club shaft extractor has a slotted externally threaded member and an internally threaded member. The externally threaded member, using its slot, is placed on the shaft, and the internally threaded member is placed on the shaft over the shaft's grip, and these members are then joined by their threads. A vise then clamps the shaft such that the club head's hosel touches and centers in a tapered cavity in the externally threaded member, and the internally threaded member touches the vise. After the hosel is heated to weaken the shaft's adhesive bond, while preventing rotation of the externally threaded member, the internally threaded member is rotated in a direction which reduces the thread engagement distance, thereby increasing the overall length of the joined members and pushing the head away from the shaft. This extractor is relatively low in cost, using items commonly possessed by club fitters to reduce the number of additional parts required.
