How to Build Sheet Metal Racks

Lay two 96-inch boards on edge, parallel and 45-inches apart. Set four 45-inch boards perpendicularly between them on edge so they're each spaced 30 inches apart. The two outside boards should be flush with the ends of the 96-inch boards. Screw through the 96-inch boards and into the ends of the 45-inch boards. Use 16 screws for this task. This is a shelf to your sheet metal rack. Repeat this process three more times so you have four shelves in total.

Lay a timber flat and draw four pairs of lines across the timber that are spaced 3 1/2 inches apart. The pairs of lines should be spaced 12 inches apart, with the two outside pairs 4 inches away from the ends. These lines are perpendicular to the 58-inch edges. Repeat this process on the other timbers.

Cut along the lines with your handsaw to the depth of 1 1/2-inches. Rotate the timbers 90 degrees and pound out the the section of wood with your hammer and chisel. Each timber should have four 1 1/2-inch-deep-by-3 1/2-inch-wide grooves. These grooves will support your shelves.

Set the shelves from the first step in each of the grooves in the timbers. Screw through the inside of the shelves and into the timbers. The four outside timbers should be flush with the ends of the shelves. Use twelve screws for each shelf.
