I have the build your own bug, but I live in a small apartment so no power tools except a compact scroll saw and hand drill. My wood 4X5 contraptions have to be simple in the extreme. I try to work with hobby plywood and pre cut dimensional wood strips as much as possible. This usually limits the project to a box camera although I did pick up an old 4X5 kit built camera (not a Bender) that was sold by Calumet in the early 1980's. It was a basket case that had to be rebuilt but I managed to come up with a camera that has front movements at least. Now I just need a lens that will allow for movements.
