Hello there, Firstly I am new to Apug, so hello all. I would be grateful for any suggestions for a table-top developing tank which can be inverted without leaking. I have been using two paterson type 4 tanks for a long while (25yrs plus) and they are now leaking badly when inverted (they never were completely leak-proof). I have recently tried the rotation method of inversion again but this has resulted in uneven development (more development closer to the edge of the film). Not sure why (developer, perhaps?), it never used to happen. So I think it is time to get some new tanks. Any suggetions would be gratefully recieved.
