I plan on cutting a slot at the bottom to allow the film holder to slide in and plan on mounting a Speedioscope Jr shutter with a pinhole in the top. A couple of 1/4 - 20 inserts for the tripod mount and it should be done.

    Nice job.

    woah nelly!

    I would love to take something like this out just to see the looks on peoples faces ... It would be a real conversation starter

    I'm interested to know how it would work with wind, is the aluminium jointing stiff enough to cope ? ... or is this perhaps staying at home and doing studio work ?

    The aluminum is rigid enough to use in the field, which was always the intent. Strong wind will be a problem , but its a problem with any LF camera. I can't wait to try it this Spring.

    Greg,
    nice use of 80/20, I've been toying with the idea of an 8x10, using 1.5in 80/20 for a monorail, with a rack gear within one of the slots, and using their delrin linear bearings.

    You don't need to use the 1.5 inch. This camera is from the one inch size and works well. I used the brass rack gears for extra strength , but delrin should work fine.

    Here's a pic of my 4X5 from the back. A similar idea I think.

    At the moment (saturday) it's cold, really, really cold. so I've shirked my house duties and started building a quickie 8x10, the rear standard, back and bed is finished, hopefully tomorrow I'll have the camera finished up and a set of bellows made for it. just a basic 8x10, rear tilt and rise, front rise, swing, shift and tilt. Basically a quick, not too fancy field camera just to get back into the swing of shooting 8x10 again.

    I didn't say it was going to be pretty! actually I only worked abut 6 hours on it saturday, and as soon as the coffee kicks in, I'll go back at it today. At one time I had a B+J 8x10 Commerical (technically I still own it, if I can find the person that borrowed it, 3 lenses (165 angulon, 305 Caltar/ilex and a 355 G-claron), my 4x5 with a 180 Sironar-N, all my light meters, etc. Some friend, huh?) Some of the design of the B+J is clever, not elegant, but clever in a 'let's make lots of cameras cheap" way. the standards are dirt simple. On my camera, I'm just going with geared back focus, front focus is get it close and lock it, so that makes it a little easier, I'm not going for super accurate, just a box with film at one end and lens at the other, mostly plywood and some 1" thick cherry I had left over from a project a few years ago. Hell, I'm not even T&G'ing the bed, butt joints, glue and screw. If it wasn't so cold, I'd probably machine most of the parts out of .125" aluminum on my CNC router, but it's in an unheated buiding and it might hit 30 today. I haven't CNC'd my mill yet, and I hate manual milling. I fugure by time I get a few hundred sheets pulled, I'll have designed a far better field camera in my head and then I'll take some time to build it.

    CNC huh .. home made ? I'm in the process of making one with steppers and servos (using both to see which I prefer working with) - firstly it's just going to be a dremel style quick and lightweight job but that will help me make a bigger one with proper milling bits ...

    One thing I love about tools is that you can make better tools with them (because we add our hands and brains into the system I guess)
