It needs to be dry enough that the water doesn't run, or pool in the bottom. The sponge works fine, when used properly.
I use the sponge, followed by a blow-dryer, if I need to use it again quickly.
So your saying it can be some moisture there? Yes the sponge stops the water, but it is still moisted after use. Is there a problem to load new film while it is that way?Quote:

Good idea :)Quote:

Except if t leaves fibres/lint.Quote:

I wrecked an expert drum when I dried it with a hair dryer - I assumed the plastic inside the drums was as thick as the plastic at the top - it isn't! It's very thin blown plastic and shrinks with heat so that the drum touches the back of the film.. Very annoying. However, I do now have two drum tops and they're the most difficult to dry.
I use high quality kitchen roll pushed into the drum using the sponge and then use a separate high quality sponge to get rid of the last drops (or at least to 'spread' them enough to evaporate quickly). I then put them in the airing cupboard next to the immersion tank. Normally it's dry within ten minutes or so..
As for the lid - hold it firmly and spin it around fast for a while and the water gets centripetally emitted :-) ten minutes in the airing cupboard and all is well..
I also dry the nozzle in my ATL2300 before I attach the drum - you can get drips from it if you're not carefull

Yes, that's what I'm saying. As long as there's not enough water to get on the front of the film before the presoak or developer gets to it, there's no problem. You can test my claim with RC photo paper to satisfy yourself it's safe.Quote:

Tim- I use the blow dryer on the cold setting. Haven't had any problems.Quote:

That is fortunate! Otherwise you might be forced to try attaching a sponge to a stick, and that seems like an insurmountable technical challenge.:rolleyes:Quote:

If you don't get the chambers dry, the film can stick when inserting it.
When I use the sponges, I look into each tube and have to tilt the sponge in order to smear any water droplets. The sponge does not absorb all the water, but it can break the surface tension of the droplets so they evaporate much more quickly.
Paper towels are compressed dust. I know some people have good results, but I won't use them.
Not all blow driers have a setting with no heat. If I resort to a blow drier, I never use heat because of the delicate nature of the inner drums and because I don't want a heated drum when I am developing film.
For BTZS tubes, you can wrap a flour sack towel (no dust) around a dowel rod and jam it in there. I would never do that with a Jobo!
I roll up a cotton lint-free teatowel ("glass cloth"), stuff it in there and wind it around a bit. Or just stick the film in wet and do a prewash so that it's completely wet.
Can I slightly hi-jack this topic and ask if caffenol developer will harm my Jobo 3005 drum?
Jon
It will make the drum smell like sh$t and make you want to throw up, but other than that you should be ok. :)Quote:

Hello Tim.
I also have an ATL 2300, my question for you....you mentioned you use the expert drum, does it fit right on the 2300?? or is there some things you need to change??
thanks for the info !!

This is exactly what I do too.Quote:
