    The 8x10 camera has what movements? It looks like front rise/fall and tilt. If that's all, that certainly simplifies construction! How much draw bellows did you go for?

    Re: Homebuilt 8x10

    Front rise/fall, tilt, swing and shift. The back is mounted rigidly on the carriage that rides the focusing rod, but, with some work, shift, swing, and tilt could be added there, not sure about rise/fall... Draw is short... about 9 1/2". The rear standard is the moving part (not the front), so I wanted to keep the track from sticking out so much that it impaired focusing on the gg when the rear standard is towards the front. My interest is landscape, so that seemed appropriate.

    Perfect for a big, beautiful 240mm Sironar-N f5.6.
    Or, one of the Metrogons we have messed with.

    You bastard! Yea, I put mine in front of a big-ass Packard but the shutter vibration - I couldn't bear to even try it. Shame on me.

    Ya know that lens was designed to use a yellow center filter? It was part of the optics. Now I gotta dig through the shop...

    Would mind sharing how you added the shutter to the Metrogon?
    I recognize the clamp, but the rest is a puzzle.

    Re: Homebuilt 8x10

    Jac, I'll do what I can! I dug the Metrogon up (had not messed with it in a long time), and it's now mounted on a lensboard for the homebuilt 8x10, with a Packard shutter on the inside of the lensboard. (the shots above are of the half-plate AK1, not the 8x10) That was the last time I took it out to play - could not stop tinkering and had to try it on the homebuilt, so I took apart the half-plate lensboard mounting! The Packard and the lens are not connected in the 8x10 configuration (helps with vibrations?)- I left an air gap between them inside the bellows. The fuzzy I-phone shot is terrible.

    I found the shutter I had it mounted to when on the half-plate (AK1), but not the lensboard. The shutter is an old German shutter (Berlin?) and has 41mm threads on the front and back. I'll have to unmount it from the Packard and play with it on the shutter to figure it out again, but maybe old shots below (the following post) will help you see ... sorry, it has been a long time! It may have vignetted a lot while on the shutter, if I remember correctly...

    Re: Homebuilt 8x10

    As I said above, these old shots how how I mounted it to the German shutter: I pressure-clamped it! You can tell the half-plate's lensboard size was a bit small: the three screws are all slightly angled and get to the very edge of the lensboard. Good thing that tripods are stable! As I said, I remember the combo vignetting: will look through my negatives...
