The tip of the stylus should be 240mm from the pivot. In approximate terms, the armboard mounting hole should be such that the cartridge stylus will "overhang" the record centre (spindle) by a distance of around 17mm for an arm that is of 240mm Effective Length (distance from stylus to armboard mounting hole centre). Roughly check this by swinging the stylus over the record spindle.
