Some will go to .035", but few will, willingly go that small. So, the only answer to the small overall cross section of a specific note/wire is to go real small with the copper. This makes string makers break out in a cold sweat, tbs.<G> In order to get a Trichord of correct proportional size and decent inharmonicity, with consistancy, the copper needs to be workable. There is the rub. They just can't make a Trichord small enough w/o manufacturing problems. Hence, I choose not to put them through that, if it is possible to get the same musical/ tonal results with bigger Bichords on the same note. It's a job, I know how to do, but I choose to let someone else do it..<G> </FONT></DIV> <DIV><FONT size=2 face="MS Sans Serif">The string size for E32 was .033" core and .055" wrap. That takes a highly skilled string maker on those sizes! It's above the call of duty imo.<G> Fortunately the strings are short enough that there will not be excessive deflection while winding, (so I've been told). </FONT></DIV> <DIV><FONT size=2 face="MS Sans Serif">Then, to add to the mix, the strings needed to be made on an ASAP situation, as the client cannot afford to have the piano down for more than a day and that will be over her Christmas "vacation" time.
