DIY Focal Plane Shutters?
So I've got this idea, dangerous I know, for a camera.
Hand-held, MFish, ground glass and/or uncoupled rangefinder / zone/hyper focused. Full front movements.
Trouble is, I'd really like it to be able to use barrel lenses. Image circle will be dealt with, but basically I'm trying to figure out the best way to get a 6x9 or larger focal plane shutter as close to the film plane as possible (in case I use a really deep wide-angle or something). I'm wondering if it makes any sense to try and design one - loosely based on a speed graphic or similar curtain shutter.
Or if I should just grab a speed graphic and re-purpose it. I'd hate to do that for a number of reasons, but it does seem like the quickest way to get a known quantity. Otherwise, suggestions for large FPS are welcome, as are info on simple mechanisms (Thornton-Pickard, Graflex, Leica?, Nikon?). Don't need higher than say 1/250 to start. Let's also suppose I had access to a precision machine shop...
Thanks for entertaining me...
