Abstract
The method of fabricating a metal shell golf club head includes forming a core to the form of the inside surface of the shell; forming a plug integral with the core to project outwardly therefrom, the plug formed to outline peripheral shape conforming to the inner peripheral edge of a sole plate opening in the head shell; forming at least one gripper finger opening and at least one locking recess in the side of the plug, the core characterized as being soluble in a fluid solvent; forming a wax shell about the core while locating the plug in fixed position in a mold to hold the core in predetermined position and while maintaining a locking plunger in the formed recess; and removing the core and plug relative to the wax shell by dissolving the core and plug in the solvent; the core being transferred between stations (at which the (a) and (b) steps are carried out) by gripping and bodily displacing the plug which is integral with the core.
