On a 100 year old piano, I'll be hesitant to go with more than 30 cents or so overpull in the high treble.<br>
<br>
I do a lot of pitch raises, and among 60-cent pitch raises on 100 or so year old pianos, I'd say that better than 90 percent are done without strings breaking. Sometimes you'll have one or two break, and sometimes they all just start popping - but not often.<br>
<br>
I had a 1900 Everett grand in original worn & rusted to the nub condition in my shop a couple years ago. Just for fun I wrenched on a good number of tuning pins with the AccuTuner on to measure how high I could pull strings sharp before breaking. On this particular piano, in the tenor and treble, I was able to pull all of them 100 cents sharp without breaking and many went 200 cents without breaking. None made it to 300 cents.<br>
<br>
If they break, and you lower pitch prior to pulling it up, then the string was weak to begin with - or the scale was horrible.<br>
<br>
And anyway, starting about this time of year, it's too cold in Winnipeg to do anything anyway! Eat a big meal and hibernate until spring breaks! ;-)<br>
