David Nereson said: " Had a string break in the low tenor during a pitch raise on a 1983 Everett console. Decided to put on a universal string and leave it if it sounded OK. (Would order custom string if it didn?t). Measured the string on the tapered slot gauge and it said # 8, so that?s what I put on. Wouldn?t pull up to pitch ? it broke. Have only had that happen maybe twice in 25 years. Brand new strings can usually be pulled way over pitch and still not break. So tried a # 8 ? instead, thinking it?s meant to be at a higher pitch than the # 8. Nope, it broke too! Now, the winding on the original string is aluminum or nickel (I assume), not copper, but should that matter? It?s the core wire that holds the tension, right? I measured them all when I got home and the original string?s core wire is .037? , the # 8 measured .039?, and the # 8 ? measured .038?, I believe. Shouldn?t that be close enough? Should I go back and try a # 9? I?m going to send in the original and have a custom string made, but I?m wondering why the universals broke way before they were up to pitch. No, I didn?t see any burrs, etc. on the upper plate bearing, pressure bar, etc. --David, You'll need to run that on a scale evaluation program. I don't have time to calc that, but you can be sure that there is a wide variance between copper/silnic/aluminum tensions. The aluminum wrap thingee is an "Edsel Idea" IMO. I doubt that you can even get a "replacement" made, so you'll need to evaluate the scale and come up with a suitable "rescale". That's one I haven't done, yet. I'll be happy to do that for you, if you don't have either Scale Master or PScale to do the calcing. Regards, Joseph Garrett, R.P.T.
