<DIV><FONT face=Arial>FWIW, I pitch raise pianos that are up to 100 =
cents flat
in one pass on a regular basis. That is, of course, followed by a "fine" =
tuning
pass. Only on rare occasions do I have a string break on a large pitch
raise.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Alan: If I understand you correctly, you tune =
the piano to
A440 by ear and then use an ETD and do a pitch raise? Why not just use =
the ETD
in the first place? Isn't that what it's for? Maybe I don't
understand.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I experimented with a 100-year old Everett grand =
in my
shop one time to see how far above pitch you could go before strings =
popped.
Quite clearly these were original strings. Typically you could go 200 to =
400
cents sharp before they broke.</FONT></DIV>

<DIV>I also can't imagine bringing a piano from -100 to +25 but you =
don't have
to. But if each string can't stand being up to pitch, they're going to =
be a
problem, anyway. So ... </DIV>
<DIV> </DIV>
<DIV>For a piano that much off, I'd set a very quick temperament to =
440, tune
up and down quickly, then use the ETD for an over (or under) pulled =
tuning
from A0 to C88. </DIV>
<DIV> </DIV>
<DIV>Condition of the strings, especially at the pins, the hitch =
loops, and
the V bar/agraffs might have some bearing on my choice of procedure, =
but I
have only rarely broken strings, even on big raises. And in those =
cases, aside
from pianos so rusty they might have been brought up from the Titanic, =
it is
usually a case of the elasticity being gone from the strings. If you =
lube the
bearing points, etc., but then feel the string stiffen and stop =
yielding as
you pull it up, you can suspect that the strings are genuinely shot =
and that
next noodge is going to result in a resounding "twaaang." If =
restringing isn't
in the cards, I have left a couple such pianos at 20 cents flat and =
tuned very
gingerly.</DIV>
