I think some people here enjoyed my last camera project so I'll post this new one too.
I started working on this on Friday and managed to get a lot done over the weekend.
The design is a 24x96mm frame size on 35mm film, using a Schneider Super Angulon 47mm f5.6 lens. This lens doesn't cover 4x5 as it only projects a 123mm image circle, but at 105 degree field of view. I'm using most of that in this design, something around 98 degrees FOV diagonal.
Got a lot of the main parts going this weekend. The top and bottom from maple, the wraparound front from 1/16" aluminum, and the film plane, as well as the takeup spool. The design uses a salvaged sprocket roller from a trashed Soviet camera, and a couple plastic gears to serve as a simple frame spacer. No frame counting. There's a clutch bearing on the top of the takeup spool to keep the film tight. The viewfinder is a 21mm-equivalent view size from eBay. It will be a little small, I think, but it will give a good idea for the image position vertically. Horizontal framing will be a little bit more of an estimate.
