Motor Base

[pemongillo]

I am tired of hand rotating my Jobo tank. I would like to get a Beseler or Unicolor (auto-reversing) drum from Ebay, but don't know if my 2500 Jobo drum is going to be long enough to work. I'm at work so I can't measure the drums demensions, but it can't be much more than six inches long. Anyone out there know it my Jobo tank will work on either of these motorized bases ? Thanks.

I just measured the distance between the rollers on my Uniroller and

it is 5 3/4" from the outside edge of each roller.

I have the 2551 drum that holds 2 4x5 rells, but if your tank only

holds 1 I think you'll be in trouble. When I put the tank on it

appears to "walk" just a wee bit while it agitates, probably about

1/2" -- it walks back and forth so there is never any danger of it

falling off, but you'll need to take that into account.

I use a Uniroller with my Jobo 2583 which is the 2nd largest tank

of the 2500 series.

Why not built a sleeve for the tank so it will stay on the rollers. I

do think "hand" rotating gives superb negs because of the

anonymous/asymetric motion imparted.

Believe it or don't . . . I'm using the Unicolor motor base with the

Unicolor print drum to develop my 4x5 sheet film. It accomodates 4

sheets at a time. No "walkng/wandering" problems (just keep it on a

level surface). Always perfect, even development. I also develop 35mm

and 120 roll film in Patterson tanks on the motor base. Never better!

I have used a uniroller with the 2551 tank to process film for

several years with no problems. recently, i added the Expert 3010 to

soup 4x5 film in also. Both work.

One footnote. To keep either drum from walking along on the

uniroller, I placed the tank on the roller, saw whenre it touched and

added large rubber bands around the tank fore and aft to keep the

tank in place. Never had a problem since.
