20130170900 | GLUELESS JOINING DEVICES FOR INTERLOCKING WITH HOLLOW SHAFTS - A glueless shaft joining system, apparatus and method are disclosed. An expandable insert, half-out insert or outsert is disposable at least partially into the inside of the shaft of an arrow or other tubular member such as a golf club shaft. A set screw can be tightened to expand finger elements to lock the insert and arrowhead attached thereto in place. Alternatively, a screw can lengthwise contract base and wedge elements along contacting portions of respective ramp portions, thereby expanding the effective outside diameter of the device inside of the shaft to lock it into place. In either case, a component, such as a broad head, can be aligned, removed or indexed as desired. | 07-04-2013 |
