Developing in Expert Drums by hand? (No JOBO)

[laz]

It has occcured to me that an Expert JOBO drum might be used "manually" without a JOBO. Does this make any sense at all?

the only problem I see is how to get the chemistry in each hole for the film there are 5 of them in the expert drum

with the Jobo it rotates and the chemistry flows in threw the lift. With out the jobo how would you accomplish the same thing?

I know that there are folks who use a motor base that is not a Jobo, so there must be a way to get the chemicals in. I have had great success hand rolling a 2500 series Jobo drum floating in a tank of tempered water. I can imagine you could do the same with an Expert Drum, but I am not sure. I do not believe that traditional inversion would work, but I might be wrong on that.

I have heard of people using some sort of funnel that rotates to facilitate the filling of the drum but no one I have known has done that. I am not saying it cannot be done just that it is a problem to work out.

Maybe (or probably) I'm not doing it right, but I just use a funnel and pour it rignt in then stick it on the Beseler roller base. I use Rollo Pyro and it involves a presoak and so far (6 batches) I haven't had any problems.

This is what I had in mind. Do you use it this way from start to finish?

That's who it was!

Only 8 to go...

Yup, right in the sink with the roller base on the counter. All the chemicals are put in this way. I've noticed that I need to tilt the drum a little bit or I get "sloshing" when I pour fast. Only happend once.

I've always used a flexible funnel from the auto parts store. Start the drum turning and pour in through the funnel. Works fine but as other have pointed out you can just pour it in and then start rotating. Also I setup my system to rotate the large diameter Expert drum two times before reversing. This is similar to what Jobo does. Others seem Ok not even turning one complete revolution before reversing. Or you could get a motor base that doesn't reverse and just flip it over by hand after a couple turns. So lots of people using the Expert drums this way.

It floats?!?!?!

Geez, I've been tossing the thing around in my hands, rolling across the kitchen floor on my hands and knees, even made a little roller base out of my kids' legos....it floats! what a revelation. This will make things much easier!

THANKS Paul.


I'm so excited, I just wanna leave work and go home and dev some film right now.....IT FLOATS! Why didn't I think of that?

I have a super large one, so I have to use a very big tank. It also is a bit too shallow for "logrolling" so grasp the top and spin it, occasionally changing directions. I swiped this idea from the BTZS tubes, which I was considering investing in when I was having so much trouble with unevenness with my Jobo and a motor base.

Now a Lego roller base, that is ingenious. Did it have one of the little Lego motors too?

I thought about it but, was in a hurry. Maybe next time. One could even rig up a little computer controlled "Lego-Lift" I suppose.
