Is there a typical percentage of the flat portion of rolling mill rollers that should be used – to the exclusion of the rest? I vaguely recall an instructor telling me to use only the middle half and not using ¼ each side, but I’m not sure if this is specific to the particular mill in that studio or always the case.
If the latter, which I suspect is the case: Does this vary according to different brands? I’m considering Pepe. Maybe Durston is different – such that I can get more useable width out of, say, 100mm of flat Durston vs 100mm of flat Pepe. … And does it make any difference whether the rollers are strictly for flat or a combination of flat and wire? I’ve consulted what I would consider to be the logical resources at my disposal (McCeight, Young, Ganoksin, the Internet at large) but not found specific guidance on this matter.
Thanks very much!
