I was more upset with uneven development.
I only have a Cibichrome print drum that will fit 11x14, the drum has a cup at the top to catch dev you pour in so that when you tilt it sideways it delivers all at once and you get very even dev, for a print... But the neg doesn't stick to the wall well, so the cup won't hold ENOUGH developer... That's the issue, but I have no other tank/tube that will hold enough dev....

Actually it has mostly to do with marketing, at least as far as Jobo print drums are concerned.My jobo manual (and the cibachrome tank manual too i think) says not to process film in paper tanks. Mostly it's to do with the anti-halation layer on the back of the film not coming off when the film's hard up against the tank wall, but there might be other problems from it too.
Pre-wet the negative.
Are you using print-paper negatives, or film?

Tried tray developing?
I've nearly finished my first 'suitcase pinhole' camera, just gotta check it for light leaks, then I'll put some 8x10 or so kodalith in it.
I've done 4x5 kodalith in the mod54, rodinal 1+200 for 2 hour stand. Not sure how well that'll translate to trays, might mean I have to twiddle my thumbs in the darkroom for 2 hours...

There is no reason not to process any and all films in Jobo print tanks. In fact we have numerous customers around the world shooting 11X14 and 7X17, using Jobo 3062 and 3063 drums with great success for both color and BW.
Can you process 8x10 prints in a 6005 tank?
You must be asking about the 3005 Expert drum - Yes, it is the only available drum dedicated to sheet film processing, for sheets up to 8X10, max 5 sheets at a time.
I think Matt's right. I process a lot of paper negatives and I've been reading the experience of other people processing x-ray film over at F295. It sure sounds similar. With paper negatives the trick is to pre-soak them for a good amount of time, at least 2 minutes, and you must make sure the paper hits the water in a smooth motion, without splashes.I did, I always do...

Even after the pre-soak, the first few seconds in the developer is critical. It needs to cover the negative quickly and smoothly and the pre-soak gives you a little more time to do this ( without the soak, it is very difficult to avoid uneven development marks. )
Uneven development can also be trickier to avoid if your developer is dilute or cold. I do that on purpose sometimes, but then I need to be extra careful. I occasionally develop in dektol diluted 1:8 with ice water. The negatives can take 10 minutes to develop, but it can also knock the contrast down so far that you can see clouds in the sky along with shadow details. When I do that I extend the presoak and really make an effort to have it hit the developer all at once.
I process my 11x14 paper negatives in a tray ( plastic for storing paper from the office supply store, with a lid ) and my 8x10 in a plastic pitcher that has a good sealing lid. With both of these it took some practice so learn how to get the developer to roll over the negative smoothly and evenly and quickly.
Just make sure you're exposure times are in minutes, not seconds, and you won't notice the raindrops in the image ;-)
And bring a can of hot tea with honey as well .....

So I can do larger films in my 2830 and 2840 paper drums? I'll have to try that out now. How do you get rid of the antihalation backing? Can you just wash it off after fixing?
