I am in the last throws of constructing a bulk paper roll dispenser for Kodak or Fuji RA4 paper. This is version 2 and this time made from aluminium sheet. The Mk 1 version was 8mm 5 ply wood and I found that there must have been some sort of chemical fumes coming from the wood because there were odd mottled marks along each edge. (I had half expected it). This box, for a better name, will take a 12" x 98m roll of paper which will give me just under 235 12x16 sheets and of course more if I cut them smaller. Roughly speaking this will save approx 40% of the cost of cut sheets (Fuji). The construction will be with cut sheets of aluminium secured at the edges with multiple 'pop' rivets and a light tight seal between the metal faces. The only tricky part is to make a light tight slot so I can feed the roll onto my guillotine. That was also tricky with the Mk 1 version. If anyone would like the plans to make their own, I will post them onto this forum once it is finished and working correctly.
