A cam lock connected with a fence assembly includes a handle portion, a top carrier and a bottom carrier connected by a threaded shaft. The handle portion and top carrier are positioned above the fence assembly and a work table or surface; wherein the bottom carrier is positioned below the fence assembly and work table or surface. The top carrier and bottom carrier both have a pair of alignment arms with a space positioned therebetween, the alignment arms of the top carrier nest with the alignment arms of the bottom carrier. The handle portion and top carrier both have cam surfaces that engage one another such that when the handle portion is rotated around the axis of the threaded shaft the handle portion is raised or lowered thereby raising or lowering the bottom carrier, thereby locking or unlocking the fence assembly in a quick, durable, easy and accurate manner.

A method and apparatus for manufacturing an aircraft structure. A drivable support may be driven from a first location to a second location to bring the drivable support together with at least one other drivable support to form a drivable support system. A structure may be held in a desired position using the drivable support system.
