Abstract:
The method of checking the loft and lie angles of an inwardly-directed cylindrical bore in a hosel of a metal golf club head relative to a ball-striking face and a sole of said club head to enable varying at least one of said angles in the event said hosel bore is misaligned from a desired end loft or lie angle; comprising the steps of:providing at least one target on a surface; clamping said club head in a predetermined location and position to aim the axis of the hosel bore generally at said target; providing a laser beam projector on one end of an expanding mandrel in a coaxially-aligned relationship with said mandrel; inserting the end of said mandrel remote from said projector into said bore while said mandrel is contracted to a diameter smaller than said bore and thereafter expanding the mandrel to snuggly fit said bore; activating said projector to direct a laser beam from said projector at said target; and, in the event said beam and target are misaligned, bending said hosel relative to said club face or sole in the appropriate direction said laser beam aligns therewith.
