FAMILY="SANSSERIF">Several months I asked about bobbling hammers in =
a grand. I
discovered that the shank lenght was too long. <BR><BR>I now have a =
similar
problem with a D. But this time, I've rebuilt the action with new =
Steinway
parts, (new h,s,f and wipps). There are three notes that are driving =
me nuts.
Unless I really smack the note, the hammer doesn't want to check. They =
boble
so bad that they hit the string on the rebound. <BR><BR>The regulation =
is just
like the other notes, (dip, l.o.,drop, etc.). Not only is key dip just =
like
its neighbors, but when I increased key dip, it didn't solve the =
problem.
There is enough damper lever clearance. I've adjusted the back checks =
to where
the hammer checks almost back down on the cushion. When I try to make =
it check
earlier, it catches. I've bent the checks so that the rake is enough =
to clear
the hammer on the way up, but still catches it on the way down. I've =
reduced
spring tension to the point of almost no rise, and I've sanded the =
backs of
the tails. I even changed wippens on one key, but the problem is still =
there.
