I have a 12x16 Rapid Rectilinear lens that I rescued from a junk bin and am cleaning up. I have a few questions:
1. If stopped down far enough, would it cover 16x20? I am guessing not.
2. Should I measure its focal length from the ground glass to the waterhouse stop slot? I am thinking yes.
3. I have to make waterhouse stops; how close to my calculated dimensions should my holes be? I don't want to have to buy drill bits in some odd in-between size if I can avoid it.
