Description
This simple tool can be used to align the bowling ball to zero pitch position in the bowling ball drill press if you are using a quick clamp drill chuck. The shank diameter is 10mm.
Tighten this carefully into drill chuck and put the bowling ball into drilling jig. Then align the table so that this zero pointer fits to the ball surface correctly from both (x&y) axles.
