    Lol, ^^^

    Yeah, having a laser cutter makes the job so much less tedious!

    I really like the 4x5 field camera on the Kirby site, but he doesn't mention what the bellows dimensions are or where he got them. I'm thinking for my first, it might be best to get an off the shelf product to keep things simple. I'm currently looking at the Rodenstock Ysarex 127mm lenses, I am wondering if I can put enough travel in the Kirby design to use it. I saw a bunch of these lenses for sale for cheap, but not many 150mm lenses under $100. The cheaper to start with, the better. Seems the Rodenstock lens covers 4x5 just fine, anything I should be aware of or reasons I should avoid these lenses?

    My construction efforts so far use matboard, cardboard, scissors, a big swing-arm paper cutter, tape, glue, time, effort, patience and the recycling bin. Someday I'll graduate to wood. Current project is an 8x10 paper negative camera using the B&L rapid rectilinear lens from an old Kodak 3A ( with one element removed to get coverage. )

    I'd second the idea of building it in matboard or foamcore first particularly if you are making a folding camera.....particularly if you aren't modeling it in CAD. Also, do consider the wood you use. Quarter sawn oak is crazy strong and stable.....and heavy. Straight grain cherry is a pretty reasonable compromise. Carbon fiber and cherry would make a nice combination.

    Also, I think everyone needs a water jet cutter also. How else are you going to cut out those titanium parts? Actually, it is pretty cheap to have parts waterjet cut if you have the 2D cad file.

    Titanium parts will be milled, no reworking needed after unlike waterjet. I only am thinking of red oak because I have a couple 12' boards of good quality stuff.

    RE: The Oak, Weight is a consideration but the machinability I'd think would be better with Cherry or Mahogany.

    A LF camera can be as simple as two nested boxes.

    At this point, weight is the lowest factor on my list of considerations for a working LF camera. Ultimately, the "final product" (in quotes as if there is such a thing...) will be in carbon fiber and titanium. I love working red oak, I know its properties well, its density is on par with mahagony and others, but the most important feature it has is being paid for already. I like cherry, its nice and all, but it not as tough as red oak. Plus, the red oak I have is already at <10% moisture content, extremely stable dimensionlly.

    (Can't figure out how to multi-quote on my phone)

    Gerald, your comment is not taken in jest. I have been thinking about something as simple as that for my first working mock-up. Mainly I need to figure out exactly which back and inexpensive lense I want. The less money the better, and repair is not out of the question.

    It's worth looking on the Large Format forum - you need to be a subscriber though to see & use the For Sale and Wanted section (it's free). One seller has some new LF (5x4) camera backs for sale at excellent prices.
