This rack is mounted on the end of my workbench, to the outside of the bench legs. The planes do not extend past the end of the bench. I was concerned with hitting the handles or blades with my feet, which happened a few times but hasn’t been an issue. This mounting serves a dual purpose – it creates a “torsion box” for the bench leg, resisting side to side movement. The position has not interfered with pieces hanging off the bench – If that happens I can remove the plane(s) for clearance. It’s worked well having them right under the bench, close to where they are used. My shop walls are covered with shelves and all kinds of things hanging, so a cabinet was out of the question. With motorcycles, reloading equipment, woodworking tools, and associated “stuff”, space is a premium. The base is birch plywood, and the pockets are oak, screwed together and screwed to the ply base. Finished with shellac. I’ve read about ply outgassing, causing corrosion of iron/steel, but I have not had any issue.
