Re: [APML] Paterson Tanks

[George Anderson <georgea@cam.org>]

As long as the reels are submerged there is no difference in the
developing time. In college we had dunk tanks that could take up to 18
reels at a time (six tubes of three) and the time in the soup was always
the same no matter what the reel count was.

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:-)

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.

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.)
