Ok, so I acquired a box full of dark room gear from a friend of mine a few weeks back.
Included in this are 2 patterson tanks - 1 5 roll tank and 1 single roll tank, the single roll tank does not have a lid, swappable with the 5, but also the tube that goes down the centre of the tank is missing.
Being that I will probably develop 1 or 2 rolls at a time, is it feasible to load my film onto a spool and put on the bottom of the 5 roll tank using empty spools to keep the bottom one in place, and then just use enough chemical to cover the bottom spool.
