Eric,
I currently use a 30xx jobo drum to process 20x24" fiber prints, never had a
problem with it, no collapsing paper and no dents of the rib that are
visible in the paper after drying and mounting (one common poblem of
fiberpaper in jobo drums). But you are correct in your assumption that a
bigger drum could induce these kind of problems. As a DIY drum would have
smooth inside walls I expect that the wet fiberpaper will stick even better
to the drum than what it already does in a jobo drum....I hope at least :-)
Hopefully I can give it a try somewhere in the near future.
Huib
