Abstract
Certain disclosed embodiments concern making sports equipment, such as golf club heads, using polishing marks to facilitate removing material from as-cast work pieces to produce a final thickness within a desired specification, such as 0.6 millimeter or less ±0.05 millimeter. At least one polish mark, more typically plural polish marks, is formed into an outer surface of an as-cast article to a depth selected to provide a final product thickness subsequent to polishing that is ±0.05 millimeter of a final desired thickness. The golf club head or component is then polished at least once to remove club head material substantially corresponding to the depth of the at least one polish mark. The method may further comprise joining the club head to a shaft.

A method for making a golf club head, comprising:
- casting a golf club head or golf club head component having an outer as-cast surface;
- forming at least one polish mark into the outer surface to a depth selected to provide a final product thickness subsequent to polishing that is ±0.05 millimeter of a final desired thickness;
- and
- polishing the golf club head or golf club head component at least once to remove the at least one polish mark and provide a final desired product thickness ±0.05 millimeter.
A method for making a golf club head, comprising:
- investment casting a golf club head to produce an as-cast golf club head having an outer as-cast surface, the golf club head having a final desired wall thickness at some portion thereof of from about 0.5 to about 0.7 millimeter;
- drilling plural polish marks into the outer surface to a depth selected to provide a final product thickness of about 0.5 to about 0.7±0.05 millimeter;
- performing an initial polish to remove the polish marks;
- and
- performing a second polish.
A method for making a golf club driver head, comprising:
- investment casting a titanium or titanium alloy golf club driver head having an outer as-cast surface, the golf club driver head having a final desired wall thickness at some portion thereof of from about 0.5 to about 0.7 millimeter;
- drilling from 10 to 100 polish marks into the outer surface to a depth selected to provide a final product thickness of about 0.5 to about 0.7±0.05 millimeter, at least a portion of the plural marks being formed on a crown, a skirt and a sole of the golf club driver head;
- and
- performing an initial polish to remove the polish marks;
- and
