ABSTRACT:
An expandable shaft (B) is disclosed having one or more spaced expansion units (A) which contain swage pins (10) that are expanded radially by wedge members (14). Operators (D, E, F) are used to move the wedge members axially to expand and retract the pins. In a preferred form, the operator includes an operator member (30) which may be rotated to move an operator rod (38) axially. The operator member (30) has a first axial position in which the operator member rotates to move wedge member axially and a second axial position in which the operator rod is positively locked against rotation so that the operator cannot turn to loosen the clamping action of the pin against a core.
