Experience with Jobo Roller Base?

[blee1996]

Hi

I use Jobo CPP2 and 3005 for developing 8x10 film. However. it is a bit cold to work in the garage during the winter month. So I'm considering manually rolling 3005 in a small bathroom using the Jobo roller base. 3005 with 1L of solution is too heavy for inversion.

Does anyone have experience with this roller base? Good, bad? Thanks!

I have one and used it for a little while to process film. It works fine, but I ultimately preferred agitation by hand.

I built my own roller base years ago and used it for several years. Worked well.

I used one for doing 20x16 prints (too big for the CPE2) before I had trays big enough. I do not think I have ever used it for film.

My experience has been with Beseler and Unicolor motor bases with 3005 and 3006 drums (with auto-reverse disconnected).

I fill my drums while they are rotating on the motor base (w/ hand-held funnel and plastic tubing). A little more difficult on a non-motorized roller base.

These are very nice. Parts are interchangeable with everything Jobo.

Works fine. I use mine to develop black & white film in my bathroom.

I do have a Unicolor motor base as well. May deactivate the auto-reverse switch and give it a go first before spending the money on the Jobo roller base.

I use the Beseler motor base in bi-directional mode when making prints. No issues. Why deactivate it on your Unicolor base?

The Jobo Expert Drum 3005 has much larger diameter than the Unicolor tank, thus it will not make a full turn before the auto-reverse. This will result in film not properly in contact with chemicals.

Ahh that makes sense.
