    That's (almost) exactly what I have in mind. How does this work with tilts and shifts? Does it exaggerate the movement at the film plane?

    My Seneca only has rise & fall on the front standard. The back has enough tilt & swing for landscapes. So I don't know the answer to your question. I do still have the CAD drawings I made for it and I'd be happy to share. I only used a table saw and sander to build it.

    Thanks, now all I need is a table saw.

    I'd love to see your CAD drawings. They are sure to be better than my pencil scratchings.

    The problem with tilts and shifts is that the lens is abit of a ways down a tunnel, and the opening of the tunnel often vignettes the back glass. the bigger the shutter and the holes in the lens boards and the smaller the aperture the less vignetting but but this setup is a problem that way. also the tilt is now way away from the nodal point.

    This is the problem to which I was alluding. I wonder if this presents a serious problem or if it simply means that you will have to limit the range of movements.

    Thanks, that looks really well made. I kayak with a cabinet maker who has offered to help with any construction. I'm sure he can smooth out some of my technical limitations.

    I think you just have to pay attention to the GG
