Holy Moly That's a lot of Stainless Steel!

It remenbers me the first films that I used to developp in college, I made my own tank with a plastic tube of 1.5 meter, used to fill it with the film attached to a little weight... Worked pretty good but it was for just one film, not fourteen... !
 
Good question, Ray! I too would worry about the pouring time. I have a tank that holds 4 reels of 35mm, and that's plenty big for me! That monster might be a good one for doing Diafine, as time is not a critical issue there.
 
Someone is going probably buy this puppy just for the reels. If you had two or three of these, you really could cut down your processing time on multiple rolls, by using the dip and dunk method of developing negs, abeit with the lights out.

I'd have to guess that this tank must hold at least 4 liters of solution. I doubt if one of my wimpy funnels would suffice for this monster.
 
With tanks larger in capacity than two 35mm reels, better control of development times is better done by "dunking" a string of reels, on the center wire spindle, into the tank (lights out, of course) than attempting to pour liquid in through the opening in the top. All of the reels can be immersed in just a couple of seconds this way but more than one tank will be needed.

Four reel tanks can also be used well by pouring the developer into the tank with the cover removed. It only requires a few seconds to pour a quart (or liter if you prefer) into (or out of) a four reel tank.

The larger tanks do retain the advantage of inversion agitation and temperature control if you keep the tank in a water bath during development. A tank as large as the one shown does seem a bit over the top.

i was inspired by this thread and thought i'd take a shot of all my PLASTIC tanks & reels but i started to add stuff and got a little carried away...

Wow, Joe, seriously nice Beseler enlarger and Gra-Lab timer! Same as mine... But all my tanks and reels are metal. :)

I used one of these in a lab I once worked at. It was dip and dunk. But someone said "oh, you should use one of these". Someonehow, the boss said "just try it". You have to pour in the dark for speed. Adjust for about 100ml loss cuase..umm, its dark. Once in, now I was in pretty good shape back then. But I had 2 of these that I had to agitate for the first 30sec/60sec. Then the usual. Man, my arms were sooooo tired after the first few minutes.

Its easier to put chemicals in tupperware, go to the bathroom, turn off the lights, and do some type of dip/dunk.

I don't recommend this at all.
