    Re: List of peculiar fabrication tricks

    This reads like two MEs sniping at each other over the cube sides. As the assembler waiting for them, if the parts weren't face to face to tighten against each other I would spin on a jam nut to keep...

    Re: Wanting fast lens for 11x14

    John is talking about the Wollensak Vitax portrait lenses, their older name was Wollensak Royal portrait. Some of them have a "fuzzulator" knob that softens the image by varying the gap between the...
  3. Re: 5x7 Madness: is it safe to use 1920's holders for critical work?

    The sheath holds the film then tucks into the slot and spring clip in the ends of the holder. A lot of fiddling to get the sheath in and out. The sheath should seem too long, but be the correct width.
  4. Re: 5x7 Madness: is it safe to use 1920's holders for critical work?

    My solution to this question was to buy up as many cheap holders as I could off the Bay. I tested for light leaks eliminating some and then loaded and used each holder a couple of times. The ones I...

    I can certainly commiserate with your problem, much as I like the Shanghai film, the price difference is not so great that I would not switch to HP5 given the same circumstances. You might want to...

    Having used a fair amount of Shanghai I found this somewhat surprising, so I went to check my own negatives. The Shanghai film is slightly narrower and longer than the HP5, but not so much as to not...

    Re: Help taking apart lens cell

    The flange focal length with that cell will be longer than the focal length of the positive cell alone. A 10" cell might focus at 12" or even 20". Try using just the positive cell, if you don't have...

    Re: Thin Gage Aluminum Supplier

    Re: kodak commercial 8X10 restoration project

    Steel wool and magnesium are not a good mix, the magnesium will rapidly oxidize from the tiny bits of steel that come off the wool (think thermite). Try Scotchbrite pads if you do need an abrasive.

    no, it reduces the amount of light. Depending on where you place the stop it can make the image sharper or distort the image.

    From the photos of the pre-war it looks like you revolve the back 45 degrees and unscrew and remove the four retaining tabs. Apparently you have to get it to revolve first.
