A very simple form of hinge can be made as shown in the sketch. It is merely a matter of cutting out two pieces of flat steel, A, punching holes in them for screws or nails, and fastening them to the box corners, one on each side. When the box is open, the lid swings back clear and is out of the way. A hinge of this kind is very strong. For a light box, the parts can be cut from tin. - Contributed by Chas.
