A billet (10) is pressed with a first blocking punch (36, 38). Thereafter, the billet is rotated approximately 90. degree. A second punch (50) is pressed against the billet while a split ring die assembly (58) substantially surrounds the billet and constrains outward flow of the steel. The split ring die assembly includes projecting regions (64, 66) matingly received in recesses (14, 16) created by the first blocking punch. A finishing punch (90, 92) is pressed through the billet to complete formation of openings (94, 96). Preferably, a trimmer (100) removes any flashing from the finished billet.

The present invention generally comprises a golf putter having a putting surface with a negative loft angle of about -10. degree. to -2. degree. The putter surface strikes the ball at approximately the center of gravity of the club and above the vertical centerline of the ball, imparting overspin and eliminating the tendency for the ball to skid, bump or become airborne. The negative loft angle is such that the putter face contacts the ball above the centerline with each stroke, imparting topspin on the ball 100% of the time, independent of variable putting conditions. An alternate preferred embodiment of the present invention combines the negative loft putting face with a convex putting surface as circumscribed by arc of radius at least 5 inches and at most 84 inches. This convex putting surface is designed to minimize the trajectory errors caused by planar face putters by producing a ball trajectory which in most cases reduces the misalignment created by a nonzero contact angle between the ball and the putter face. In other words, if the angle of contact with putter face of the present invention is misaligned by 1 degree from that which would produce a straight line trajectory to the hole, the ball will travel a path that is less than or equal to 1 degree to the right or left of the hole, thus producing a more accurate alignment with the hole.

A forging (A) is received in a split ring (B) which provides peripheral support to a forging peripheral wall (14) and an upper peripheral flange (16). The forging and the split ring are supported by a nest member assembly (C) as a trimming assembly (D) moves longitudinally to trim the forging flange and a forging bore (10). A punch (74) with a hardened cutting edge (80) moves axially through the forging bore and interacts with a nesting assembly cutting edge (60) to trim the bore. Concurrently, a trim die (90) having a cutting edge (96) interacts with a split die cutting edge (36) trimming the upper flange. The split ring restrains a central portion of the forging from puffing peripherally outward in response to the punch being urged therethrough. The interaction of the trim die and the split ring inhibits the upper part of the forging adjacent the upper flange from being drawn in toward the forging bore by the interaction between the punch and forging. In this manner, the forging bore and flange are trimmed concurrently and deformation of the forging is restrained.

A preheated billet (A) is disposed in a billet receiving region (20) of a lower die (B). The lower preforming die defines a throat region (30) which is smaller in transverse cross section than the billet receiving region and disposed immediately therebelow. The lower die further defines an enlarged relief region (40) which is larger in all transverse dimensions than the throat region and disposed immediately therebelow. An upper die (C) includes a billet engaging surface (50) which has substantially the same transverse cross section as the billet receiving region. The upper die is forced downward by a hydraulic press or the like into engagement with the billet. As the upper preforming die continues downward, the billet engaging surface is telescopically received within the billet receiving region pushing and deforming the billet ahead of it. With continued downward movement, the billet is forced into conformity with the billet receiving region and is extruded through the throat region to hang within the relief region. In this manner, a billet is formed in part in substantially conformity with the billet receiving region and in part untapered or draft-free with the cross section of the throat region.
