Golf handicap systems and methods to calculate a golf handicap

A method of casting a hollow golf club head includes casting the crown with a plurality of thin regions having a thickness of less than 0.030 inch separated by a plurality of ribs. The ribs act as cast-in runners that enable the thin sections to be formed without voids despite the extremely thin cross-section. The crown may have an additional region of substantially uniform thickness that is substantially the same as the thickness of the ribs.

Golf club head having a crown with thin regions

A golf club head is formed with a crown having an aperture with an arcuate rear edge and a forward edge that is substantially parallel to the striking face. The aperture is transected by an arcuate rib that extends from a region proximal the heel end of the crown to a region proximal the toe end of the crown and is concave toward the striking face. A pair of linear ribs extend radially outward from the arcuate rib to join the arcuate rib to a perimeter region of the crown. Openings formed in the aperture by the ribs are filled with an organic-composite material such as graphite epoxy.

Metal-composite golf club head

A golf club head includes a hollow body having a front wall, a crown and a sole. The crown has a thickness dimension measured between its inner and outer surfaces. An outer edge of the crown extends in a generally arcuate path between heel and toe ends of the hollow body. A plurality of thin regions in the crown is arranged in a matrix pattern. The plurality of thin regions includes a first row of thin regions disposed adjacent the outer edge of the crown and a second row of thin regions disposed inwardly of the first row of thin regions. The crown thickness dimension in the plurality of thin regions is reduced when compared with the crown thickness dimension in other regions of the crown.

Metal composite golf club head

A metal wood-type golf club includes a weight member disposed along the interior surface of the bottom wall. The weight member is sized and distributed so as to increase the moment of inertia of the golf club about a vertical axis extending through the center of gravity as well as lowering the center of gravity of the club head itself. The longitudinal position of the weight member is selected as a function of the loft angle of the club face. The weight member is moved forward for a club having a small loft angle and moved rearward for a club having a high loft angle so that the vertical gear effect about the center of gravity partially offsets the natural backspin of the club to a greater or lesser degree depending on the loft angle of the club.

Metal wood golf club with progressive weighting

An iron-type golf club head includes a body having a front face arranged for impact with a golf ball, a heel end, a toe end and a beveled sole. The beveled sole has leading and trailing edges with a ridge located between them. The beveled sole includes a primary surface and a secondary surface, both of which vary in width from the heel end to the toe end. The primary surface is located between the leading edge and the ridge, and the secondary surface is located between the trailing edge and the ridge. The primary surface has a first width dimension adjacent the heel end, a second width dimension measured along a center line located substantially between the heel and toe ends, and a third width dimension adjacent the toe end. The first and third width dimensions of the primary surface are less than the second width dimension of the primary surface. The secondary surface has a first width dimension adjacent the heel end, a second width dimension measured along the center line, and a third width dimension adjacent the toe end. The first and third width dimensions of the secondary surface are greater than the second width dimension of the secondary surface.

Iron-Type golf club head with beveled sole

The present invention comprises a method of making a golf club head by casting a molten titanium alloy and thereafter removing the alpha case that is formed on the surface of the titanium by means of a conformal milling process. The conformal milling process uniformly dissolves the alpha case without distorting the underlying metal. The reduction in wall thickness caused by the conformal milling results in a concomitant reduction in the weight of the part without any loss in the critical impact strength of the part. In fact, impact strength is increased. This weight can then be redistributed as a supplemental weight member, which can be used to lower the center of mass of the club. The weight member can further be positioned on the sole plate or club body in such a way so as to permit fine tuning of the location of the center of mass of the club, as well as shaped so as to increase the polar moment of inertia of the club head about the golf club shaft.

The present invention relates to a bearing insertion device which is specifically adapted for use in conjunction with an archery bow. In its broadest context, the present invention includes a C-shaped frame with an upper arm and a lower plate. A threaded driving member is adjustable positioned through the upper arm and is adapted for cooperation with the lower plate. At the lower end of this driving member a bushing pusher is secured. This bushing pusher is specifically adapted to engage the bushings found within archery bows.
