So I've been making a new monorail 4x5 for a couple of weeks now.
Work is going slower than I'm used to. But it's going.
Some WIP pics for y'all to hammer at.

As mentioned earlier it's a 4x5. Back is only landscape as I realized quite late that I should make a different shape/size if I wanted to be able to do something in portrait. I had the back frame and the bellows made already at that point, so I just let it go. Maybe if i make an 8x10...

It's meant primarily for lensed photography, but maybe I'll figure out what pinhole size i should throw on there at certain extensions and go for that too. Primary lens for this one is going to be a Schneider Kreuznach symmar-s 210mm/5.6. I have a buch of old projector lenses and stuff that might work too, but for now not really thinking about those.

Rail is a long thread. It's got a turn knob on it right now. I think that needs to turn into a crank post haste. Getting the front post from the front to the back or visa versa takes quite long. Which is not cool. Or I need to start thinking about maybe adding and electro motor it. Is that even a thing?

Back bit has an aluminium tube on rake tane springs to hold the back in. Black stuff is the insulation for windows and doors and whatnot. It's there for a snug light tight (Fingers crossed. First time using it on the sides instead of underneath the holder.) fit. Blowtorched the tine until glowing red and then wrapped it around the aluminium. Steel cools way too fast. Especially if you're just throwing stuff at the wall and seeing what sticks.

Things left to do: Figure out that crack situation, fastening bellows to front and back, fabricate rails for the front and back movements, sourcing something other than butterfly bolts for the movements (if need be make something up), tripod bolt, maybe treat wood with something for color / endurance.

Ok, other than some finishing touches this is done.
I had some luck in scoring a piece of ground glass out of an old fancy slide projector. It's plastic and way finer grain than the frosted glass i was using. Thinking of getting a fresnel lens for on it tho. It's nested in a sacrificed wooden 4x5 film holder.
