I have some questions reguarding (16x20) ULF cameras. I want to start on a 20 year old dream but want to discuss it with someone more knowlegeeable than I so I know it is possible or not. Thanks. Looking forward to your reply. Bob Timo,

The bellows are a big cloudy spot for me, because of that tight fit needed, but I found a book and a couple resources that seem to have a formula for coming up with good measurements. I'll post when I get tot hat point. I hadn't thought about the short focusing distance when I started, but as I looked around I noticed a great design point on the Lotus camera that allowed the back end of the front standard slide to slide past the rear standard. Basically if you drop the brace down so it doesn't overlap, then the two slides can run past each other. As I make progress I am really starting to feel like the design will hold up. I fear that "Oh sh..." moment when something doesn't fit or collides with another part, but the whole thing goes along so slowly, it has been giving me time to watch out for those sorts of things. So far so good. And as final note; do you have any pics up somewhere to take a look at? I love looking at home-builts, there aren't many around to look at, so its neat to see what other builders are up to. Cheers, Timo Eric,

I have built a 4x10 back for a zone VI camera. It is a little bulky and I am still chasing down a light leak. I also made a bunch of sketches, but a lot was built by the seat of my pants. My biggest problem was making the bellows and not verifying the finished dimensions. It ended up the bellows was an inch larger than the back leaving me no way to attach it. I ended up making the back twice. I noticed that my method of shift and swing is pretty much the same as your sketch. The last problem I had was I couldn't compress the camera enough for short lenses due to a couple protruding knobs. Sometimes longer isn't better. Good Luck Eric Timo:
