| 20100313672 | METHOD AND APPARATUS FOR TESTING SHAFTS - Methods and apparatus are provided for testing shafts, such as golf club shafts. In one embodiment, the invention can be characterized as a shaft tester comprising: a frame; a first shaft support supporting a first portion of a shaft at a first fixed position; a second shaft support supporting a second portion of the shaft at a second fixed position; and a third shaft support supporting a third portion of the shaft at a third fixed position. An actuator couples to the third shaft support to displace the third portion relative to the first and second portions to deflect the shaft. A sensor couples to one of the first, second and third supports outputting a signal corresponding to a force exerted by the shaft due. A controller controls displacement of the shaft. In some embodiments, the shaft is rotated while being deflected. | 12-16-2010 |
