<DIV>Of course this is why we need to always begin a service appointment with a
disclaimer, especially if the piano hasn't been tuned a long time and is far
below pitch. Wim, with that disclaimer you can include all your
paranoias...Mine, up till now, was simply that a string could break with the
pitch change and that it was out of my control. I put the onus on the
customer for lack of service. In 28 years I have never had a plate or
soundboard crack on me while tuning...I do still have an aversion to strings
breaking...it never fails to make me jump!</DIV>

TYPE="CITE">Set the temperament, tuned octaves to the top, then started in
on the bass, <BR>and while tuning bass unisons, I heard "the big bang".
Now the first <BR>octave of the plain wire section was suddenly a
quarter-step flat, but the <BR>bass and rest of the treble were still up to
A=440 level. So I took the <BR>action out and with a bright light
inspected the plate very closely and <BR>could find no cracks. There
was one hitch pin that had two very small <BR>hairline cracks around it, but
someone (maybe the factory?) had relocated <BR>the hitch pin about 2 inches
lower, out of the cracked area. I searched <BR>and searched and could
find no evidence of plate cracking, rib separation, <BR>bridge splitting,
pinblock separation or anything else having given way</BLOCKQUOTE><BR><BR>I
heard that once, and the soundboard cracked. Perhaps there is no rib
<BR>separation, but the crack could still be there somewhere. The customer
heard <BR>it, and called me back later to complain about a "funny" sound. I
told her <BR>the soundboard cracked, and that there
was nothing I could do about it. <BR>This is one of the reasons I never
raise pitch an old upright. It happened to <BR>me once, I don't want to have
it happen again. <BR><BR>Willem </FONT><FONT size=2
