<DIV><FONT size=2>Many tuning pins in the base of my Kawai KG-1D =
(5-foot, 1984)
have become jumpy in the last 4 years. The piano's former RPT (and =
my
mentor) said he never encountered jumping pins.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Two conditions have changed with my piano:
1) I tune it now, and 2) it was cleaned with =
ammonia water
(even though I told the cleaners to leave it alone) following some smoke =
damage
from a fire in the other side of my duplex in 1994. This leads to =
a few
questions (from a novice):</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>1) Why might this problem develop? Have =
I
inadvertently done something wrong? Could it have resulted from =
the
cleaning? (There has been no other contamination.)</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>2) The pins are still very tight. =
Could I
remove the pins, and pound them in again to eliminate the jumping? =
or,
should I drill or ream for a 3/0 pin and install new pins?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>3) How much material is best for a reamer to
remove? If there is too little of material to remove will the =
reamer
burnish the hole instead of cut?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>4) What other options for a guaranteed fix are =
there?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Thanks for even reading this long-winded =
request. And
thanks to all of you on this list who have been so helpful in educating
me.</FONT></DIV>
