Abstract:

A workbench has at least one drive member to clamp table members against one another. The drive member has a receiving tube and a crank tube. The receiving tube and crank tube are coupled with respect to one another for telescoping movement. One of the tubes has a threaded member and the other tube has a thread engaging member.
