Swing-up shelf serves as supplemental surface

Big projects take up most of my workbench's surface, leaving little room for my tools. To keep them close at hand but out of the way of the project, I designed this easy workbench add-on: a swing-up shelf. A 2×4 support arm mounted to the underside of my workbench with a lag screw swings out to prop up the hinged shelf. When no longer needed, I just swing the arm back under the bench and let the shelf swing down, out of the way.
