Dale,
I suppose this depends on the definition of the word "correct".
Actually, I was making a statement regarding the fact that the Sanderson =
Break % formula calculates out at about 4% higher than whatever formula =
that Del uses. Del stated that the Sanderson Break % formula was =
incorrect. I honestly don't know which is "correct" for typical modern =
wire but am willing to accept Del's postiion that most current wire has =
a higher tensile strength. So, I don't get all in a bunch if the =
Sanderson Break% formula tells me I have a note at 68% Break Point =
because by Del's calculation it would be at about 64% of Break Point.
There does not appear to any differences of opinion regarding Tension =
calculations. They calculate essentially the same.

Nice to hear form you. Well ,I guess if I like the sound of the old =
L strings I could simply measure I.D. & O D. , have them rerpoduced & =
just forgo the scaling altogether except I'm interested in accurate =
measurments & even tensions.. So how does one know if the tension =
programs one is using is actually the ( correct) one?
Ari Isaac was the one I had the experience with the L strings many =
loong years ago. His scaling for my taste was always (almost way to =
heavy & irratic. In fairness he' probalby learned a few things since =
then as we all have but I never hear from any one on this list that uses =
them. I do know one can scale a stwy B set to heavy & kill the sustain & =
natural beauty of a stwy Bass end.
AmHIK.

The Sanderson (Pscale) Break Percent formula calculates the top 10 =
bichords of an original Steinway L scale to be in the 55% to 67% of =
Break Point range. In fact, from what I have been able to determine, the =
Sanderson formula calculates Break Point at about 4% higher than =
whatever formula Del is using.
Given that the tensile strength of today's wire is said to be =
higher, I just interpret the Sanderson calculation with this in mind.

What are you using to calculate the percentage of breaking =
strength? If it is the formula presented by Al Sanderson and used by =
Tremaine Parsons, it is incorrect.=20
The Model Ls I've measured come to the high 50%/low 60% range. At =
least when compared to the real-world tensile strength of the wire in =
use today.

List
Speaking of strings, I've had the pleasure now of using =
about 6 sets of the Arledge strings & I like them very much. I like the =
neatness of the wraps etc. But as much as this I find the tone color of =
the scaling a bit darker thru out but I find it especially refreshing =
in the top of the bass scales where typically many makers get a bit thin =
& whiny sounding which I believe is a tension problem.
I haven't checked but I'd guess at a bit heavier scaling =
being employed which, in my limited scaling experience gives a darker =
tone with more power.
IE the Old 1920's stwy L scale in the region of notes 20 - 26 =
were scaled toward the 70% of breaking strength & they sounded awesome. =
When on occasion I have replaced sets where the tension was reduced in =
this area the tone suffers greatly. ON having it corrected the tone came =
back. I'm not finding this weakness in the Arledge strings at present.
I'm interested in any ones feedback be it objective or =
subjective.
