You might be on to something, and some people have used sinar 8x10 cameras to create 11x14 cameras. (www.glennview.com for one of them...) The problem of going from 8x10 all the way to 20x24 is the sheer weight of a film holder or a piece of groundglass of that size... You might end up with something a little too flimsy for 20x24... And lenses that cover 20x24 tend to be big and heavy process lenses that might not be too kind to the front standard of the toyo... Just my 2 cents... (by the way, if you do make this camera, I'd love to hear from you about it so I can include it in my new ULF page ( ulf.janvanhove.com ) Cheers, Patrick Jan > HI, > > I am still goofing around trying to build a 20x24 camera.
