FIGS. 7 and 8 illustrate an alternative, stylus 130, in which the outer surface of small part 132 is threaded, tapered part 134 is similar to tapered part 114 in FIG. 6, and the large part 136 has a hexagonal opening defined in the end so that a hexagonal wrench can be inserted in it to turn stylus 130, causing the threads of small part 132 to engage inward-facing threads in opening 40 in body 42. The straight shape of stylus 130 facilitates its removal and replacement in this manner. Also, large part 136 has annular groove 140 formed at an appropriate point along its length and O-ring 142 can be rolled onto the end of large part 136 until it seats in annular groove 140, where it can help provide a tight mechanical connection between stylus 130, frame 12, and a weight, as described below, while allowing at most “negligible momentum” to be transferred through stylus 130 to body 42; the term “negligible momentum” in this context refers to an amount of momentum that does not exceed approximately 110 percent of the momentum solely attributable to the mass of stylus 130. O-ring 142 could, for example, be made of Viton®, an excellent rubber-like material for damping or preventing vibration that also resists the effects of chemicals and weather and maintains its elasticity.
In one successful implementation, flexible layered part 384 has been implemented as a “rubber boot” that can be slipped onto and off of solid part 382. Therefore, flexible layered part 384 can be manufactured by molding an appropriate material, such as ethylene propylene diene monomer (EPDM) or Buna N rubber or another appropriate elastomeric material to obtain the desired shape, and then slipping it onto solid part 382, which can be manufactured in substantially the same manner as described above in relation to FIGS. 9-11. Alternatively, flexible layered part 384 could be molded directly on solid part 382 with any appropriate process. EPDM is extremely durable and resists weather and corrosive agents, and, though it does not always damp vibration as well as Viton® would, it is more economical to use. Flexible layered part 384 has been implemented successfully with EPDM material as thin as 0.025-0.030 inch, which may approach the minimum thickness at which it can be molded.
As described above, the O-rings can be Viton® O-rings to more effectively prevent vibration as well as providing chemical and weather resistance and long-lasting elasticity. In addition to their effects on preventing vibration, the O-rings are sufficiently elastic that they do not allow any significant momentum from weight structure 380 to be transferred to stylus 350, so that substantially all momentum from weight structure 380 is transferred through arms 52 and 54 (FIG. 13) to lower lobe-like portion 322 of golf club head assembly 310.
A golf club head assembly with a stylus and weight or weight structure as described above could be produced with materials that are finished in various combinations. For example, a weight structure's solid part could be made of plated mild steel and could have a finish that contrasts with those of the golf club head assembly and the stylus, such as electroless satin nickel plating in contrast with an anodized black finish or a black chrome finish in contrast with a silver or marble-like Eternalum® finish.
