Come to think of it, wouldn't the thin, strong, model aircraft-grade
plywood be quite adequate for most of the sides of such a box? This stuff
is widely available in most model airplane-oriented hobby shops in sizes
and thicknesses that would be quite adequate. Just paint the inside
black to eliminate all light leakages (and watch for any minor splits, etc)
It would be lighter than using commercial (building) grade plywood.

Actually depth of focus from gg to film plane is harder than orientation.
Talks with Canham indicate that this machining is the major expense in
making the cameras. (and its is dependent upon the holders for sizes >8x10!!!
as there is no ANSI standard).
