Having spent 30 years in a variety of small-run machine shops and prototyping operations, I still enjoy hacking thing together.
Happy to discuss any ideas or projects you might have. Either a camera from scratch, or modifying an existing camera, or making Franken-cameras...
This is a 6x9 camera made from a few different parts. The film back is a Graflex Singer. The back panel it attaches to is from a Burke & James press camera. The focusing helical is from a Pentax 50mm f/2 lens. There is a machined insert to hold the Ilex Acugon 47mm lens in the focus helical.
That's about a 21mm equivalent. Pretty fun to use in crowds, etc. Scale focusing, guesstimated framing (although I do have a finder that mounts, holding this at chest height and guessing works well).
Because this is a prototype for my personal use, I haven't yet finshed off the joints, etc. Electrical tape is an effective- but ugly- preventer of light leaks. Proper machining and assembly and finishing is better, of course.
