RE: [APML] Paterson Tanks

["Thom Iwancio" <tiwancio@sc.rr.com>]

George, Andrew and Frank, thanks for the info.  This is exactly what I
was looking for.  I was really surprised that Paterson didn't offer
on-line manuals or data sheets for there products.  I guess I am just
getting spoiled from all the companies that do.

Well, since no one else is speaking up, I guess I'll blunder into this
topic myself.

The Patterson tanks that I've bought all came with a little clip ring
that can be used to clamp the spool(s) and keep them from sliding up the
agitator shaft while pouring/agitating.  It looks like it's made out of
the same stuff the spools were made out of and you just clip it on and
slide it down.  One reel in a 2 reel tank, two reels in the 5 reel tank,
no problem.  The tanks all have instructions for estimating the fluid
capacity for each reel printed on the bottom.  It just takes a little
foresight to remember to look at the chart before you fill the tank:-)

Keep in mind, I bought my last Patterson tank about 18 years ago (they
just don't wear out!) so they might not include the little clip anymore.
I would suppose you could rig some little ring or a piece of tubing,
maybe a fat rubber band that would keep the reel from climbing out of
the chemicals.

As to the matter of whether or not one or two reels being developed at
the same time has any effect on how the film develops is completely in
the eye of the beholder.  I've never been able to tell any difference.
As long as the chemicals completely cover the reels, it doesn't matter
how many reels there are.  (I'll probably get all kinds of argument from
that.)
