Hi Murray, I've also got one of those 18x24 bellows which I picked up on ebay a couple of years ago and which is still sitting in its box. I find that there are a number or issues to need to be resolved but I haven'tresolved them yet. But I have not put my imagination full time on it.
The questions I need to resolve are: 1. What kind of frame to build for the back standard and the front standard, considering that the back will need to hold a very large format film or paper, that the front will need to hold the lensboard and that the two should preferably be parallel. 2. How do I get the front and back standards aligned together rigidly to a frame that will allow the bellows to extend or compress. In the case of an 18"x24", the considerable weight of the bellows makes this a more difficult problem to solve than for a 4x5 or an 8x10 bellows. 3. What kind of light-tight contraption do I build to hold the paper or film against the back standard. 4. Is there a way that I can build a contraption that will allow me to place several sheets of paper or film, so that I don't have to run back to my darkroom after each exposure? I haven't tought about this for some time. I did check around on the internet for sites that talk about building large format cameras and I found quite a lot of useful information. My problem is that I am not very good as a woodworker and I just don't have the right tools. I'd be interested to hear about your ideas for your camera. I don't see any problems discussing it on the list, unless we get into minute details.
