Abstract: A golf club head of the metal wood type has a body formed entirely from one billet of high strength aluminum alloy with a separate sole plate of the same or different material secured in a machined recess on the lower face of the body. The body has an internal, empty cavity machined through a lower wall of the body, and the walls are thicker than in conventional cast stainless steel metalwoods. The front, striking face is machined to any selected bulge and roll, loft and face angle.

Abstract: A golf club putter has a putter head including a plurality offset surfaces, each of the offset surfaces containing a respective portion of an alignment figure that has a periphery enclosing an area. Each respective portion of the alignment figure includes respective sections of the periphery. Disorientation of the putter head may be detected by transposition of each portion of the alignment figure with respect to the other portions. Correct orientation of the putter head is indicated by precise alignment of the portions to present the alignment figure without apparent distortion.

Abstract: A golf club head has a body having a front, striking face, an upper wall, a lower face with a plurality of threaded openings at selected positions, a rear wall, a heel and a toe, and a separate sole plate for securing to the lower face of the body. The sole plate has a plurality of through bores aligned with the openings, through which fastener screws project to secure the sole plate to the body. The fastener screws are selected from a plurality of sets of screws of different weights, whereby each fastener screw may be selected from any one of the sets to control total head weight and weight distribution.

Abstract: A golf club metal wood head made of lighter weight material than stainless steel, such as aluminum alloy, has a front wall with an outer striking face, an upper wall, a lower wall, a rear wall, a heel and a toe, and an internal cavity milled out through a wall of the head to selected dimensions to provide a selected front wall thickness, and a varying wall thickness around the remainder of the head to provide a selected perimeter weighting to the head. The front wall is made significantly thicker than in conventional heads.

Abstract: A metal wood golf club head includes a hollow body with a front wall and a lower face, and a separate sole plate for securing across the lower face to form a lower wall of the head. The body has an internal cavity and an opening in the lower face leading into the cavity over which the sole plate extends. The sole plate is secured across the lower face by a suitable securing device. The front wall has an extended portion extending downwardly beyond the lower face against which the sole plate abuts when secured across the lower face.

Abstract: A golf club fitting apparatus and method utilizes a number of different club heads, the club heads having hosel or shaft receiving bores at different angles and securing devices for releasably securing a hosel at the lower end of a golf club shaft in the bore, and a number of different shafts. The heads have different parameters such as peripheral weighting, center of gravity, and face area in addition to different bore angles. A player can select various different head and shaft combinations to test. To test each combination, the hosel at the end of the shaft is inserted in the bore, and releasably secured in position. The player then tries it out. The shaft is released, and a new combination is tested in the same manner, until an optimum fit for that particular player is found.
