Donald Qualls said:-- but if it will, I'm tempted to take it with me next time I'll be somewhere that might have a Jobo 2509N reel and see if the Jobo reel will fit over the center spindle in the Paterson tank (you must use the spindle, it's part of the tank's light trap). If so, I'll be set for developing my 9x12 and upcoming 4x5 in batches instead of onesies in tubes (and the Jobo reel alone isn't that expensive, as I recall, it's the combination of tank and reel that gives my wallet the cold sweats).
thanks for the tip. It seems that agitation might be fairly limited inside the tubes, especially with a full tank. I'll definitely give it a try.
Doing 4x5 sheets in ordinary paterson tanks....my ears are perked WAY up! Please elaborate...I have the System 4 Universal tank and reel. How do I do 4x5 in it?
k_jupiter said:I'll check it out tonite Donald. I have both the 2509n and the Patterson stuff. It might be the diameter of the 2509 that is too large for a system 4 tank.
The problem I have with the Jobo is I don't like how small the tanks (Jobo) are heightwise with that reel. The margin of error is pretty slim. Of course they are suppose to be used in rotation form, but I haven't gotten there yet. Another layer of process qual to do before I get there.

Nick Zentena said:Not even close to fitting. The 2500 tanks are much bigger. I'm not sure what you're saying about the height of the tanks? The big tanks are HUGE. The smallest tanks aren't much cheaper then the bigger ones.
Used Jobo tanks aren't that bad. You can often find a used tank for less then a new 2509N reel.

k_jupiter said:Yes, but I have the small tank. 2530 I think. I suspect if I run across a 2540 it would be just right. Of course I am at work and I could have all the numbers wrong.

jdef said:Being impatient, I decided to try another approach to developing sheetfilm in my Patterson tanks. My solution was to use a rubber band around each sheet of film, leaving a gap at the ends, forming a lopsided cylinder with a vertical slot. Works great, allows plenty of agitation, and none of the antihalation backing issues described above. I can only get 4 sheets of film in with this method, but that's an improvement over the single sheet method that I've been using. Thank you all for the inspiration.
jdef said:Have you ever ended up with a knock-off plastic reel that just won't load properly? I have one, and I've decided to try to modify it for sheetfilm use. If I'm careful, I can make the modification so that I can use both 3x4 and 4x5 film with the same reel, by way of the width adjustment feature. If it works, I should be able to get 5 sheets of 4x5 or 9 sheets of 3x4 on the reel. Anyone else ever tried this?
k_jupiter said:How do you keep the films from overlapping while processing? Those suckers will slide around while fluids are surrounding them.
jdef said:I've seen several Nikor 4x5 tanks on ebay, and a few other odd model sheetfilm tanks that look interesting.
