Subject: Expanding YC action bracket symptoms??


  Hi List,

  I know this topic has been dicsussed a fair amount at various times in
this forum.  Yesterday, I went to tune a Weber WG50(about a 5' 7" grand I
believe) which was manufactured by Young Chang.  What I found was a piano so
out of regulation as to be virtually unplayable.  Hammers were blocking
against the strings, and it took more than a full turn of the let-off dowels
to get any let-off at all.

  I didn't get very far into it, because I'd only alotted time for a normal
tuning appointment.  I did take off the top action to check for abnormal
tightness in the keyframe, but it seemed to go in and out just fine.  But
the amount the piano has gone out of regulation is of concern to me.

  Other factors:  The piano was in Pennsylvania before it came to a much
drier climate in CA, and before it got to its current location, it stayed
for some time(I think the owner mentioned over a year) in storage.

  What measurements can I take to determine if it is indeed swollen
brackets?  After checking a few sample notes, I've come to the conclusion
that the piano can be regulated, but I want to be sure it isn't something
more egregious before I spend many hours on the piano.

  Any input would be helpful!  Thanks in advance.

  I just regulated a Young Chang G 150 grand today that had the symptoms you
describe.  I tried some samples before proceeding.  All went well.
Adjustments were a more than usual, but there was plenty of adjustment left
for future regulating.  BTW, this is the first full regulation the piano
received since it was purchased ( January, 1994).
