    A couple of days ago I was working on one of our platen press cutting machines* at work. These have a matrix of threaded holes to attach the cut tools with.

    They are Italian machines but the threaded holes are on a 1 7/8" pitch. I found that very strange.

    Not sure of that terminology, but this chart details the 'fine pitched' series, which includes 0-80 etc.

    Confusing isn't it? Those danged engineers that can't use terms that the likes of us understand.
    If you're going to find the screws locally I'd try an optician since they are usually capable of repairing eyeglass frames. Size 0-80 and 1-72 are most likely. I've found both in a hobby shop at one time or another.

    Whilst we're thinking about screw threads, does anyone know the size of the screws which hold the strap brackets onto a Rolleicord V? One of mine has gone missing.
