After sawing, clamping, gluing, sanding.... and routering.....
and hand drilling a hole in brass shim stock
my 4 x5 pinhole box looks like this.
I made the back of the box to fit Polaroid, 4 x 5 sheet and roll film holders.
I need heavy duty bungee cords to hold the Polaroid back on, but the other film holders just snap in.
