Here’s a sturdy rack for storing and organizing wood dowels. Use a hole saw to drill 2-1/2 in. dia. holes in three sheets of 1/4-in. thick plywood. Screw or clamp the plywood pieces together at the corners so the holes will line up. Then screw the pieces to your shop wall or ceiling. If necessary, a 3/4-in. wide strip of wood makes a strong bracket for both holding the plywood and securing the units to the wall.
