Ok, I'm just a snot. :-) P In a message dated 3/2/2010 2:20:13 P.M.

Don't really feel like I know a heck-of-a-lot about that topic even now, but I sure knew less back then! You are correct to point that out though - anyone who has an understanding of the basics of string scales should have a reasonable handle on that.

Way-average breaking percentage of 70% at pitch yields another three half steps of pitch (300 cents) rise to approach 100%. Paul In a message dated 3/2/2010 12:37:19 P.M.

We did maybe a dozen or so and pretty regularly we would pull them about 300 cents sharp before they broke. That surprised me a bit.

We each brought our tuning wrench and took turns cranking tighter and tighter until the strings broke. It was amazing! Most pins turned 1/2 a turn or more before the string let go. Again, there is no rhyme or reason...... Mike Kurta, RPT Chicago chapter = = -------------- next part -------------- An HTML attachment was scrubbed...
