[LargeFormat] Jobo 3000 Series Expert Drums

[Skip Roessel]

The 3005 is just over 14 inches high or long without the lid, and just 18
inches high with the lid installed.  It's 8 inches in diameter.  Fits nicely on
a Unicolor or Beseler roller, with which it works just fine.

After some experience with it, suggest you use about 600 ml. of chemistry
(about 2.5 cups liquid measure).  450 or 500 ml is not quite enough, esp. if
your setup is not exactly level when rolling.  Mine lives in the bathtub with a
slight slope to the bottom.

I also made a filling funnel to introduce chemistry without stopping the
agitator.  Took a polyethylene funnel, softened it in boiling water, and bent
the snout about 30 - 40 degrees, which put a kink in it, but not a serious
one.  Now you can hold this funnel basically upright while the snout sticks
into the hole in the lid, and get a pint of chemistry in there in six or eight
seconds.  I develop B&W in pyro, and need the tank rolling when I introduce the
developer, to prevent marks or streaks on the film.  (Try the rollo-pyro from
Bostick & Sullivan; you'll like it!)
