How about a pinhole 8x10?

Use all of these great ideas

Pinhole is a lens

I may use Magnesium C1 back and box

To load one film or paper

Test with 4X5 and 5X7 as I have the set

Toyo bellows.

Another vote for a Canham 8x10. I have the wood field version, and as with any Canham, you can slide the rear standard forward. Keith sells a bag bellows for it if you want to go super-wide.

What kind of hole size does this pinhole have? Nice sharp image for a pinhole.

I would definitely go for a rail camera and NOT a flatbed. I can think of three options, all of which I've owned at one time or another. Rail cameras have the option of a shorter rails to make it more compact with less weight.

The best, easiest to find option in my experience would be a Sinar P or a Sinar F 8x10 with an F2 front standard that has long risers meant for the 8x10 camera. (I owned the P 8x10, but not the F 8x10.) For a lighter weight rear standard, Sinar made an 8x10 P base intended for copy work that weighs a lot less. But, they are hard to find.

A second option would be a Sinar Norma 8x10 with a Norma 8x10 bag bellows. These are relatively light-weight, and one can purchase extenders for the front standard risers from www.glennview.com. (This avoids having to tilt the rail for greater extension. They screw in at the top.)

A third option might be an Oschwald era Arca Swiss 8x10 with a bag bellows. The problem with these is that, there's little enough room on the front risers for extended rise, without having to tilt the rail up. My solution for this was to have S. K. Grimes rebuild the silver front risers to make them longer. (They did a fabulous job; I couldn't believe it.) But, the fabrication cost would be greater than $6C.

You wash your mouth out with soap !
There are lens designers on here.

A pinhole is a stop.

thanks...
Measured the camera and focal length is more like 100mm. My notes list the starting pinhole size of being 0.0138 inches. I know that I had replaced the original pinhole at least once to optimize the sharpness so I'm guessing it is around 0.0130 inches diameter. Shim metal used was .002 inch brass. I had found that the thickness of the metal shim material matters a whole lot.
