Claims
- 1. The method of forming a high strength, metallic, golf club head, which includes:
- a) providing a golf club head main body consisting of metal, and a metallic face reinforcement plate peripherally connected to said main body which is hollow,
- b) said reinforcement plate forming a recess bounded by a lip,
- c) providing a non-metallic ball striking second plate, and affixing said second plate to said reinforcement plate, so as to be inset in said recess and bounded by said lip, said step of providing a non-metallic ball striking second plate includes connecting the periphery of the second face plate to said lip; and including grinding said lip and said second plate to form a forwardly facing smooth head surface wherein the forward face of the non-metallic second plate is flush with the forward facing surface of the metallic lip.
- 2. The method of claim 1 wherein said reinforcement plate has a thickness of about 2 mm, and said grinding is carried out to reduce the thickness of the second plate to about 2 mm.
- 3. A golf club head comprising:
- a) a main body portion formed by casting of a first metallic material, and forming a cavity,
- b) a front face reinforcement plate formed of metallic material, only the periphery of said face reinforcement plate being integral with said main body portion to support said plate, said plate forming a recess bounded by a peripheral lip,
- c) and a non-metallic ball striking second plate received in said recess and retained therein, said front face reinforcement plate is a forged metal plate which is welded to said head main body portion in abutting relation to said second plate.
- 4. The golf club head of claim 3 wherein said forged metal plate has a looping periphery which is welded to said head main body portion.
- 5. The golf club head of claim 4 wherein said ball striking second plate defines a plane that intersects said welded looping periphery.
- 6. The golf club head of claim 4 wherein said head main body portion defines a looping recess receiving said looping periphery of said forged metal plate.
- 7. The golf club head of claim 6 wherein said looping periphery of the forged metal plate is generally trapezoidal about the non-metallic second plate.
- 8. The golf club head of claim 3 wherein the head main body portion and the forged metal plate both consist of substantially the same metal.
- 9. The golf club head of claim 8 wherein the second plate consists of graphite.
- 10. The method of forming a high strength golf club head that includes
- a) forming a thin cast metallic golf club head body having a front opening, the body forming toe, heel and rearward portion of the head,
- b) forming a forged metal plate of a size to close said front opening, and having a frontwardly facing recess,
- c) peripherally welding the forged plate to the cast body to close said front opening and to peripherally support the plate,
- d) and providing a graphite plate of a size to fill said recess, and fitting said graphite plate into said recess and attaching the graphite plate to the forged plate.
