Hello, Some stringers string two strings at a time. By `string,' I mean a piece of string, actually, going e.g. vertically. That is, some stringers put a string into a grommet, then leave the opposite grommet with the string, then continue for the next row, and then string these two strings at a time. It is sometimes said it is less precise. I don't really see why: you just need to turn more on the stringing machine (assuming a manual one), but stringing two strings at a time avoids rotating constantly the stringing machine on its axis, as you always put tension at the same place. What do you think about this (considering e.g. double flying clamps)? I also asked myself a question: assume you do that for 3 strings, and not 2. Would the 1st string of the three have less tension than the 2nd and 3rd, assuming double flying clamps? I'm not sure of that. Thanks.
