How to Make a Developing Box
Details of the Developing Box
A box for developing 3-1/4 by 4-1/4 in. plates is shown in detail in the accompanying sketch. It is made of strips of wood 1/4-in. thick, cut and grooved, and then glued together as indicated. If desired, a heavier piece can be placed on the bottom. Coat the inside of the box with paraffin or wax, melted and applied with a brush. Allow it to fill all crevices so that the developing box will be watertight. It will hold 4 oz. of developer. Boxes for larger plates can be made in the same manner. Use a small wooden clip in taking the plates out of the box, being careful not to scratch the sensitive film.
