Abstract

A golf club includes a golf club head comprising a striking surface and a body portion extending backward from the striking surface. A first indentation is formed toward the rear of the body portion and behind the left most impact point on the striking surface, while a second indentation is formed toward the rear of the body portion and behind the right most impact point on the striking surface. A first weighted element is affixed inside the first indentation, and a second weighted element is affixed inside the second indentation.

Claims

1. A method of affixing material to a golf club head, the steps comprising:

forming said golf club head having a striking surface and a body portion extending backward from said striking surface, said body portion having a heel portion adjacent the club shaft and a toe portion distant from said club shaft;

forming a first indentation on the outer surface of said golf club head toward the rear of said body portion and behind the impact point on said striking surface nearest the toe portion of the club head;

forming a second indentation on the outer surface of said golf club head toward the rear of said body portion and behind the impact point on said striking surface nearest the heel portion of the club head; and

affixing said material into said first and second indentations.

2. A method as set forth in claim 1, wherein said material is primarily made of aluminum and bronze.

3. A method as set forth in claim 1, wherein said material is primarily made of brass.

4. A method as set forth in claim 1, wherein said material is primarily made of bronze.

5. A method as set forth in claim 1, further comprising removing a portion of said material after solidifying.

6. The method of claim 1, wherein said material is affixed to spraying said material into said first and second indentations and allowing said material to solidify.

7. A method as set forth in claim 6, wherein said spraying is by thermoplasma spraying.

8. A method as set forth in claim 6, wherein said thermoplasma spraying is by plasma arc spraying.

9. A method as set forth in claim 6, wherein said thermoplasma spraying is by twin-wire arc spraying.

10. A method as set forth in claim 6, wherein said thermoplasma spraying is by high velocity oxygen fuel spraying.

11. A method as set forth in claim 6, wherein said thermoplasma spraying is by powder combustion spraying.

12. A method a set forth in claim 6, wherein said thermoplasma spraying is by wire-rod combustion spraying.

13. A method as set forth in claim 6, wherein said material is primarily made of aluminum and bronze.

14. A method as set forth in claim 6, wherein said material is primarily made of brass.

15. A method as set forth in claim 6, wherein said material is primarily made of bronze.

16. A method as set forth in claim 6, further comprising removing a portion of said material after solidifying.
