The trays I made aren’t going to work for these negatives. It’s too much film that can scratch way too easy. I’ve decided to build a 3 chamber tank that I can simply drop a film hanger into. The fact that I live only a few blocks from TAP Plastics made this an easy decision. Of course, the trade off here is that I now need to fill these tanks with much more chemistry than the trays. I’ll use a 12 volt pump to circulate water through the middle chamber and another to drain the tanks when I’m done. Steel and clips for the hanger on order, and I’ll get the acrylic and epoxy on monday.
