I will try to make some pictures ASAP. I will be able to make some better pictures when I remove the tramp for repair.
The sailbox is really nothing more than a great big toolbox like the one shown in the attached picture, with a extra door in the rear. The box was made by bending ~1/10" aluminium and pop riveting it togather at the corners. The bends, seams and extra metal are just like a good metal tool box. The top and bottom has creases along the diagonals for rigidity. (Think of a 1/2" high piramid)
There is a piano hinge in the back and 3 padlock hasps on the front.
The dimensions are based on the biggest sheet of aluminium available.
The box could be built by welding. It just depends what the builder is familiar with.
