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.
