In one embodiment, an extraction apparatus used to pull a golf shaft out of a club head comprises a hosel engagement member, an annular cylinder bore and piston assembly, and a shaft clamping device. The assembly is positioned on the shaft by passing the shaft through an axial hole in the assembly and the hosel engagement member is placed next to the head's hosel. The shaft is clamped in the clamping device so that the hosel, the hosel engagement member, and the cylinder and piston assembly are held tightly against the clamping device. The cylinder is then pressurized, thereby applying a force to the piston and an extraction force to the head which is essentially symmetrical with the shaft. The hosel is then heated to weaken its adhesive bond to the shaft so the piston is able to move and push the head away from the shaft. |
