Abstract: A method of vacuum induction melting a charge of material includes preheating a mold; inserting the charge into the mold; placing the mold into a chamber; reducing an operating pressure within the chamber; induction melting the charge within the mold; allowing material of the charge to fill a cavity defined within the mold; applying electromagnetic pressure to the charge within the mold; and applying an electromagnetic field to material of the charge positioned within the cavity defined within the mold.

Abstract: A golf club head comprising an integral toe, heel and center section, with the center section including a cavity. The center section is structured so that the majority of the weight of the golf club head is positioned at the toe and heel. One embodiment of the golf club head includes an insert located in the cavity and a second insert is located in the golf ball striking face of the golf club head. The inserts, alone and in combination, increase the feel transmitted through the golf club head to the golfer.

Abstract: The present invention relates to a golf club having a golf club head with a channel on the head. The golf club head may be a putter-type club head that is used to putt the golf ball on a green. The use of the channel on the club head provides a mass distribution that can result in a high moment of inertia so that the club head resists twisting in the player's hand when the club head strikes a golf ball. The channel also assists a player in aligning the club head to strike a golf ball. The channel may be located on the upper face of the club head so that the player can see the channel when addressing a golf ball with the golf club. The channel extends from a front, strike face of the club head to a rear face of the club head and is preferably aligned with an axis that corresponds to the desired direction of travel of a golf ball that is struck with the club head.
