Detuning a Yam C-3 to A=415</DIV>

<DIV><FONT face=Arial size=2>Hello List</FONT></DIV>
<DIV><FONT face=Arial size=2>From Sussex where we have a problem=
with one of our pianos at Glyndebourne. Doesn't stay in tune.=
This is not one I tune for there are two of us and this is a=
rehearsal stage piano. My colleague asked me to have a go at it=
while he stood by. It seems it was tuned just yesterday and=
already the top two breaks were in trouble and the effect was=
creeping down into the middle break - unisons weren't=
unison. Yuk! So I inspected it and found there is quite a lot of=
Joe G's "flag-poling" going on. Of course you recognise the=
model (it also has MII stencilled on the web beside the CA-40).=
My gut feeling is there is too much "give" in those wrest-pin=
bushings. I was just wondering whether a good old dose of CA=
might not be in order...it might just harden those=
bushings...What do <EM>you</EM> think?</FONT></DIV>
<DIV><FONT face=Arial size=2>Also just tuned down a Yam C-3 to=
A=415 at Vallotti temperament. I used my "Quadrant System" to do=
this, but since I was taking the piano <EM>down</EM> in pitch I=
started of at A=411 and went on from there. Finished in two=
passes including setting the temperament to=
Vallotti</FONT></DIV>
