No leader on my 1998 Tri-X aerial Recon film. I just load in the dark and tape it direct to the take up drum. It only costs you 4 inches or so. I have 2 partial 125 foot cans of the Tri-X and one is definitely foggier than the other, so I'm using the better stuff first. I have quite a lot of newer Plus X that is in great shape, and that's what I've loaded for the re-take (this Saturday we hope)
I've hired a couple of sherpa's to help me tote the stuff up up up. My brother and my nephew ;~'))
I had a 7++ foot long stainless steel tray built that fits in my 8' sink for doing these negs. It has 6 inch sides and is 12" wide. I take the film out of the camera in the dark and tape it emulsion side up to the bottom of the tray with ordinary masking tape. Then I do my thing. As soon as the 2nd water stop bath goes in, I turn the lights on. I never could get negs without banding doing it the bucket and bathtub way you hear about old timers doing. I'm getting good negs now with the big tray. $285 bucks. Only mistake I made was putting a 3/4" pipe bung on the end. Doesn't drain fast enough. A 2" would have been more like it. So I simply grab the sides and invert. Whoosh. Out the developer goes. Saving the fixer is slow.
I mixed up Calgon and Photoflo for a final rinse on the neg you see, and still got white water spots. Need to work on that some more. Maybe buy a couple gallons of distilled H2O for my final 2 washes, with a bit of Sodium Hexametaphosphate in the final.
