Abstract
Abstract A conventional centrifugal forcemeter having a centrifugally leadwardly extendable spindle is trailwardly provided with a fixture having an underlying trough portion abuttable against the external contour of a baseball bat, a golfclub, or other selectable athletic club. Flanking the fixture underlying trough are two plurally-tabbed rows. A flexible girthing band, preferably of annular shape and of elastic material, engages at least one ear-like tab of each fixture row and tightly girds the athletic club to maintain the fixtured forcemeter in removably attached, secure and operable condition to the selected athletic club.
