Joe and others,
Besides using trays, did you ever consider using a tube? you could build
them yourself, including a roller base, sort of DIY jumbo jobo drum.
To be able to process 30x40" (70x100cm) prints you have to buy a approx 45"
(110cm) long tube with a diameter bigger than 12" (30cm). 12" diameter gives
a circumference of 30" as 12" times Pi (3.14159) = 30" You should be able to
find such tubes easily as these are used/made for drainage/sewage. One end
of the pipe can be sealed permanetely and on the other end you put a
removable cap. Here in the Netherlands you can buy pipes that do not needed
to be glued as is a "manchet" with a rubber seal ring, just push one pipe
into the other. You could construct a funnel on the removable cap to
fill/empty chemicals from the drum and only remove the cap to load and
remove the paper. The other thing you would need to build is a sturdy
roller-base. Maybe even a motorized roller base so you can operate it single
handed.
The benefit of using drums is less space and chemicals needed, drawback is
that something like toning that needs visual feedback is more difficult.
I've been giving this a thought as I also want to make a few murals. I have
made a sketch: http://home.plex.nl/~hsmeets/jumbojobo.jpg. The drum will
need some refinement like someting of a rim in the tube so the paper will
not overlap when it is inside the drum or construct a light trap in the
filling cap so you can do all this in roomlight! etc etc.
Unfortunally I do not have (yet) the space to expose these sizes of paper
with my enlarger :-( :-( otherwise I would have build something like
this....
