MCB18:
When processing 4x5 in tanks (before I started using Jobo reels), I used homemade BTZS cylinders. In order to prevent film sticking to the side of the tank, thereby not allowing any fluid between film and tank wall, I used a piece of nylon screen slightly bigger than the film sheet size between the film and tank wall. It worked very well, but there were times when the screen watermarked/embossed the base side of the film. Also insure that the emulsions side of the film is toward the center of the tank.
Hope this is helpful.
