Claims
- 1. A golf club head, comprising:
- a) a body having a front strike surface and a cavity therein; and
- b) a strike face insert secured within the cavity and including a first layer and a second layer of insert material, said first layer having projections formed as predetermined indicia extending into said second layer and visible and distinguishable at the front strike face of said body.
- 2. The golf club head of claim 1 wherein:
- a) said insert has a front strike face; and
- b) the projections on said first layer are flush with said front strike face of the insert.
- 3. The golf club head of claim 2 wherein:
- a) the second layer includes a machined surface defining said front strike face of the insert, said machined surface being flush with the front strike surface of the club head body.
- 4. The golf club head of claim 3 wherein:
- a) said first layer is adhesively secured to said second layer.
- 5. The golf club head of claim 3, wherein:
- a) said first layer comprises a first colored opaque material and said second layer comprises a second colored opaque material.
- 6. The golf club head of claim 5, wherein:
- a) said first colored material and said second colored material are identical in all respects except color.
- 7. The golf club head of claim 6, wherein:
- a) said strike face insert material comprises thermoset rubber.
- 8. The golf club head of claim 7, wherein:
- a) said strike face insert is a cured mixture comprising a polymer blend, a metal salt of an unsaturated carboxylic acid, a free radical indicator, and silica.
- 9. A method of making a golf club head body having a front strike face, a strike face cavity, and a strike face insert, comprising the steps of:
- a) forming a first insert layer with projections formed as predetermined indicia;
- b) forming a second insert layer with recesses corresponding to the projections of said first insert layer;
- c) fitting said first insert layer to said second insert layer with said projections fitting within said recesses to form said strike face insert; and
- d) fitting said strike face insert in the strike face cavity of the golf club head body.
- 10. The method of claim 9, wherein the second insert layer has a front surface defining the front strike face of the insert, the method further comprising the step of:
- a) locating the projections of said first insert layer relative to the front surface of said second insert layer whereby said projections are exposed and visible at said front strike face of the insert.
- 11. The method of claim 10, further comprising the steps of:
- a) fitting the strike face insert in the strike face cavity with the strike face thereof and the projections of said first insert layer extending beyond the front strike face of said body; and
- b) machining the front strike face of said insert to expose the projections on the first layer at a location flush with the front strike face of said body.
- 12. The method of claim 11, comprising the step of:
- a) forming said first insert layer of a first opaque colored insert material and said second insert layer of a second opaque colored insert material.
- 13. The method of claim 12, comprising the step of:
- a) forming said first insert layer and said second insert layer of material which is identical in all respects except color.
- 14. The method of claim 13, comprising the step of:
- a) forming said strike face insert of thermoset rubber.
- 15. The method of claim 14, comprising the step of:
- a) forming said strike face insert of a cured mixture comprising a polymer blend, a metal salt of an unsaturated carboxylic acid, a free radical indicator, and silica.
