Default Tank ID and question

Old timers, your assistance please.

Below are two links to a tank that was given to me today. Three reels
which hold 8 4x5" films (or paper) each. Total 24 sheets to a batch.

The tank is 20" tall, 7.5" in diameter. The top is for filling the
chemicals.

Will it fit in any kind of roller you know of?

Looking at the close-up of the reel, Note the expressions, the bent
wires pointing a bit toward the film. They cannot touch the film. Do
you think that the emulsion should be toward the center (toward the
wires) or toward the outside, with the apron facing the wires? I suspect
the wires are to enhance agitation, but I have no clue, really.

As usual, I deeply appreciate any insight.

Default Tank ID and question

Those are King Concept reels and drum. The processors are No Longer made
by Omega Satter, for that matter neither the drums or reels. I have
found that the diameter is approximately the same as Jobo Expert drums
and therefore should work on the Jobo roller base, because the KC drums
are a lot heavier I would not consider them, the Expert Drums strain the
limits of most small motorized roller bases.

King Concept machines used a belt and pulley system and a larger motor
to drive the drums automatically.

Very helpful, thank you. I see there is little virtue in being able to
do 24 sheets of 4x5 at once if I have to build a roller, especially
because I do not do commercial processing.

However, the drum is interesting in that the lid moves in and out to
accommodate fewer reels! I might cut it to take just two reels to lessen
the load. If I burn up the motor on the little rotor base, then motors
are cheap.

BUT - any clue on the emulsion direction question? Toward the center or
toward the outside? The 4x5 acetate aprons seem unnecessary except to
make loading easier.

Thanks again, Sir.

The Jobo 4x5 (2509M) reels look pretty much like those. For the Jobo reels,
the emulsion should face the core (center) of the reel. The Jobo has a
loader that holds each sheet so you just push it into the reel. Jobo have no
aprons for that. I have a Jobo tank that takes one reel, and another one
that takes two reels. I think they made larger tanks as well, but my CPE-2
processor would not take them any longer, and processing 12 at a time is
enough for me.

Thanks again, Sir.

Twelve at a time is enough. On a very long good day that would be one
set each of N-, N, N+.

I am cutting the tank down to two tomorrow.

Took me a awhile but I found a copy of one of the KC manuals which tells
that loading with emulsion inwards toward the drum center is the way it
should be done. Interesting machines they made, the processors warmed
the drums and chemicals with forced hot air. In the end Jobo was the
last company making processors as of about 6 months back they too
decided to pursue other avenues.
