[pianotech] clunking upright stickers

[David Nereson]

    No, I haven't tried these things yet.  A few months ago the 
owner spent $400 on reconditioning, and thought that was an 
awful lot, so it would be very difficult to get her to spend 
even more now.  I get the impression from her that she thinks I 
didn't do something in that reconditioning job to get rid of the 
clunking.  But I was trying to take care of first things 
first -- cleaning, screw tightening, hammer filing, lost motion, 
let-off, softening the bangy tone, etc.
    Thanks, everyone, for the replies.  She probably won't pay 
for anything until the next tuning -- probably a year from now 
since it holds pitch really well.
    But I'm keeping all your suggestions with her customer card. 
Yes, I still use cards -- everything in one place, directions on 
the back, no computer or PDA to drag around . . . .

    P.S.  Why would wrap-around sticker cloth be quieter? 
There are plenty of old uprights with just the square of cloth 
on the bottom of the stickers that don't clunk on key return.

Have you tried replacing the hammer rest rail fetl? Also, make 
sure the rest rail brackets are are tight in the rest rail, and 
that the brackets are tight in the action brackets. And last, 
make sure all four or five action brackets are solid and tight 
on each of the bracket posts, and that none of them are loose in 
the keybed.
