    Can you draw your tube design, I'm not visualizing it...

    Thanks!

    Is there an interest out there in a mural print making workshop?

    Yes! But I could only attend if it's local to me. Or at least within a day's ride.

    I'd love to see some pictures or diagrams of your process and some examples of your work as well. It sounds really interesting. The largest prints that I've been able to make are 53x69 inches image size (see attached picture). They are partially bleached, redeveloped in thiocarbamide, and then toned with GP-1 (and selenium for the final edition). Please excuse the iPhone pictures.

    I've been using all Ilford papers, mainly warmtone and classic fibre, so I'm limited to 56" in width. I could go longer but I don't typically like to push my negs beyond 5x enlargement, so my 11x14 negs are tapping out around this size.

    Re: Big Prints??

    I'm currently printing to 21x30...cutting down from 42"x98' rolls and souping in 22x32 inch trays (homemade).

    Years ago I did 40x60's with students (all student work), souping in large troughs on darkroom floor, with one person on each side pulling up and down. Very messy and not to my liking.

    I'd like to go with something like the cut-in-half pvc pipes mentioned above - but cannot find anything online (here or elsewhere) which completely/accurately describes the "scrolling and/or rolling" procedure for large prints.

    So....could someone please describe (completely/accurately) the scrolling (and/or rolling) procedure, which I can do by myself (without help), in troughs in my 36"x16' sink, with a good degree of smoothness/consistency/safety to prints - in sizes from 30x40 to 40x60? Thanks!!

    Re: Big Prints??

    PS: I find the possibility of agitating a rolled-up print especially attractive from a logistical standpoint...but would worry about even distribution of fresh chemistry over a given time.

    My take on scrolling is that I'd do what I did with my students - lift one edge of the print high enough over the trough to ensure complete print coverage - but this sounds tedious and, for 40x60's, I'm not sure if my arms are long enough - and I'd want to make some kind of (slotted dowel?) clamp for each end of the print, which could then become handles and which would evenly distribute lifting forces. Anybody tried this?

    At any rate - my sense is that if I could possibly scroll, this would be better for the image than "rolling" a print in a trough.

    Hoping I'm clear enough on this, and deeply appreciate any replies.

    John - I will be posting videos on my web site www.bobcarnieprintmaking.ca in the Lambda fibre section we will have a video that shows how we process by hand 30 inch by 10 ft sheets of paper.
    you may find this video interesting.
    Videos are starting to be loaded , right now only one but within a week about 10-20 videos
