ABSTRACT:
A new method is disclosed of fabricating the joint between a golf club post and a drive shaft, as is the article fabricated therefrom. The golf club post to which the shaft attaches includes a circumferential recessed contour. The hollow, metal, electrically conductive golf club shaft is placed over the post, and an electric coil is placed around the shaft and post juncture. The electric coil is electrically pulsed, causing the shaft to shrink fit to the contour of the post. The electro-formed, mechanically bonded shaft is now permanently and integrally anchored to the golf club post. In a second embodiment, a non-conductive shaft of carbon fiber, for example, is electromagnetically bonded to the post, using a metallic ring, which is electromagnetically formed around the non-metallic shaft and post. In a third embodiment, the club head post is additionally fitted with at least one vertically disposed groove along the vertical axis of the post. These vertical grooves capture the shaft as it shrinks to the post surface during electromagnetic forming. The electromagnetically formed shaft shrinks into these grooves, and is prevented from rotationally or angularly slipping about the post.
