Abstract: A jig assembly is used to manufacture shipping crates essentially functioning to prevent damage to crate-bound material. The jig assembly includes a jig form and magnets. The jig form has a front portion, a rear portion, and a top portion extending between and connecting the front and rear portions. The front portion is parallel to the rear portion such that the front, rear, and top portions together define a board-receiving channel. The front portion has a pair of fastener-aligning slots and a pair of magnet-positioning bores for receiving and positioning the magnets. Fasteners are positioned by the slots and magnets. The board-receiving channel receives a first board of a crate assembly. The properly aligned fasteners may then be driven through the first board into a second board of the crate assembly so as to prevent damage to the crate-bound material. Certain jigging methodology is further supported by the jig assembly.
