bobbling hammers,

size=2 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. <BR><BR>What are some other things I should =
look
at?<BR><BR>Wim </FONT></FONT></BLOCKQUOTE></BODY></HTML>
