    Re: Pin registration system preferences

    I have a complete Condit micro-pin system, including registration punches, contact frames and glasses, etc. I've personally adapted glass for my Durst and own 8x10 registration carriers to match...

    Matt, the easiest way to stay alive in banana slug country is to never have a banana in your pack or lunch pail. Attach it to a cord at least twenty yards long, and drag it way back behind you. That...

    Re: calling all Durst 184 Laborators

    Of course the upper column could be detached from the lower, as I already mentioned on the parallel 184 thread; but then you'd have to build a strong stable wall support for that whole upper section...

    The manufacturer got the arm onto the lower column, so there has to be a way to get it off. It looks like the easiest way would be to removed the foot first, then slide the whole table mechanism off...

    Re: Minimal chem for 8x10 dev

    All such specs are fudged for a significant margin of error. I could easily dev six sheets of 8x10 in a half qt of 1:1 D76 in a tray without fear of exhaustion or surge marks. I once routinely did...

    Something more akin to Delrin or UHMW nylon, which machines well and is durable. Ordinary nylon is soft in a bad sense, and wears out quickly.

    Re: calling all Durst 184 Laborators

    There's likely going to be a lot of falloff even with a 240 lens, requiring a custom convex diffuser. But 180 for 8x10 really sounds odd. I have 180 Rodagon, but I use it for 4x5.
