    Re: 2013 5X7 LED Enlarger Head Test 2

    Well, the horizontal enlarger and the tailboard camera are one and the same, or that's the plan anyway, with a different foamboard back. It will be a wall-projection arrangement, but simple to setup...

    Re: 2013 5X7 LED Enlarger Head Test 2

    Perfect timing ! I have been looking at making an 8x10 tailboard camera (foamboard and birch-ply, nothing tricky) and the associated enlarger during the winter, and in your illustration we see the...

    Re: DIY 8x10 (or larger) Enlarger Chassis

    As well as the driving-leadscrews I assume that you have a head counterweight, maybe moving vertically somewhere at the back via wire-rope and a pulley ? And, indeed, a table counterweight too.

    If the point of the request is to make a print with black borders, rather than to print the actual rebate and edge of the negative, then try the following:

    Apart from Minox, I have never tried a bakelite tank in any size or format, but most bakelite products I have seen tend to be quite 'chunky' as the plastic is relatively weak. That suggests that...
