I epoxied a bridge for an Acrosonic #293752. String #33 was broken (the right string of G#2). I don't remember at this point if I had the broken string to measure, or if I ordered based on the left string specs. Ordered string from Schaff. It broke above the V-bar while bringing it up to pitch. I could feel too much tension before it was even a semitone away. Sure enough it snapped before it reached pitch. I spliced it - snapped again. Schaff was kind enough to replace it at no charge. I figured it was a flawed string. Again, the same exact feeling and pop. Right at the point the string begins to coil on the pin. I could feel it coming. Probably should have looked more closely before popping it. The string was straight, which tells me it wasn't catching on anything. I can't imagine why the epoxied bridge cracks should effect it. I have installed dozens of strings, and don't feel like I did anything wrong. Could it be a whole batch of string is flawed? Today I measured the left string, and it did read .001" smaller core diameter and .002" smaller copper diameter. The length of the winding looked good. I didn't think this is significant enough to break a string, but I'm not sure. (It is significant enough to give a poor unison though.) I tested the strings adjacent, lowering pitch and re-raising to see how tight they feel - they felt normal. I'm thinking of ordering from a different company, being super careful while replacing, and seeing what happens. If it works normally, I could call Schaff and ask for a refund. If they refuse, no big deal. However, if this new string breaks even after being super careful, then I'm at a loss. I will order based on the left string measurements, naturally. Has this happened to any of you? FYI the strings that broke - and yes I mic'd them before installing - were .040 core; .118 winding; hitch to winding 5 1/8"; winding length 30 3/4". The new string will be the same lengths but .039 core and .116 winding.
