Do you have a pic or link to that Alden? All my searches turn up the 35mm version. It would be fantastic to see your home made developing tank too.[/QUOTE]

My home made 70mm tank. I bought the 70mm 15' reel first and then went looking for something to put it in. It fit in an old Omega Chromega processing tube/tanks for prints. It's about 6 7/8" inside diameter. Takes 96oz of developer

The problem with the tanks was I could not invert it for agitation or all of the developer would spill out. I had cut down a 120 16oz SS tank to fit a 127 (46mm) reel and I had saved the cut off SS ring. I simply epoxied it to the top of the Chromega tanks and a standard Kinderman tank top will keep the liquid in.
I had to cut down the tank as it was quite tall. More epoxy and silicone sealer. I made this tank around 1988 and it's still going strong.

I also mad a 70mm reel that will fit in a standard 16ox SS tank. I took a 35mm 36exp reel and cut it in half. Using a dowel, I spaced the reel ends 70mm apart and epoxied the whole thing. Did this in 1978 to process 26 exp 6x6 frames in 16oz of developer. Works well
