DIY(?) roll paper safe/dispenser
I'm pondering buying Ilford FB on rolls instead of sheets, which requires that I have some means of storing and dispensing the roll. Has anyone built a paper-safe and dispenser? Are there "best practises" for constructing and/or using this sort of thing? I was considering integrating a guillotine or rolling cutter with the papersafe, but am concerned that (with a rolling cutter anyway) dragging the paper under the clamp-bar could scratch the emulsion. Do you cut roughly off the edge of the dispenser and then trim completed prints?
A dimensioned drawing of a roll papersafe would be awesome; at this stage I don't even have dimensions for the cores that it will need to support.
Do people cut a bunch of sheets from the roll and store them in a box/papersafe, or cut them for use directly off the roll?
I'd like to buy a 20" and (maybe once my not-insubstantial stock of 8x10" runs low) an 8" roll; Ilford makes both. B&H only seems to stock the 50"+ rolls of FB though (narrower ones are all RC), so where could one hypothetically be had? The local (AU) distributors are disorganised thieves so it's generally (much) cheaper to pay for 5-day international air courier from a foreign retailer than to get something through the local supply chain.
Any suggestions and/or hard-won experiences welcome...
