I know that I've read somewhere a chart with estimations of how much plain wire (in weight, or in coils with a certain weight) is needed for a complete restringing of a typical small or mid-size grand, but I can't seem to find it anywhere right now. All of you with experience, could you give me some kind of ballpark figure, or direct me to a such a chart?
The question is a general one, but the first project where I'd need to land close enough regarding needed material is the restringing of a Steinway A.
:) I had the same kind of trouble when I lived in the US for four years in the 1990's, and I'm still converting all units in my head (or with a calculator, if need arises.)
Jim: I do have all wire diameters since long ago (Röslau and Paulello 1, I use the latter for historical instruments), I just remember that I saw some kind of chart at some stage for estimating how much wire is needed for a few selected pianos of different sizes. I think the needed material was given in weight. I guess it could come in handy if there are several grands that need restringing back to back -- a situation I might find myself in sometimes in the near future.
