Hello, all. My name is Chris. My 11-year-old daughter has been learning on a Salvi Prima 38 for several months now, which is going very well. I’ve successfully replaced several strings, but now I’m having a problem. I’ve attempted to replace the 3rd octave D string (using Bow Brand natural gut #16) three times, and each time, just as I’m getting it up to pitch, the string breaks at the sound board, right at the knot/anchor.
From Googling around, it seems most likely that there’s a burr cutting into the string. I can’t see anything, though. Does a burr seem most likely to you? And, if so, how do I sand it out? The only advice I’ve found involves coating some kind of string in Brillo and then basically flossing the hole, which sounds like a mess. I saw one reference to some kind of sanding string, but I can’t find anything like that for sale anywhere. Should I just take it to the harp store (a 2-hour drive) for help? I would really appreciate any advice you might have. This one little thing is stressing me out–and keeping my daughter from practicing properly. Thanks very much.
