<DIV><FONT face=Arial size=2>Hi Daniel,</FONT></DIV>
<DIV><FONT face=Arial size=2>1/16" may be OK for a decent grand, but is probably
going to be too close for an old upright, especially if you haven't re-burnished
jacks or performed other service on the action. Stick to 1/8" throughout. And
besides, if the hammers ARE blocking on the strings, then they are NOT
letting-off at 1/16" are they? When using magnetic strips, make sure that you
are not using any force on the key to make the hammer set-off.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Are the hammers actually blocking, or just not
setting-off? You may need more after-touch. Don't forget, if you have removed
1mm from the hammers, then you also need to raise the hammer rest rail by 1mm,
and adjust capstans to take up the lost motion.</FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> letoff, blocking hammers on an
everett upright, ca 1974</DIV>
<DIV><BR></DIV>hi all<BR><BR>i'm working on this everett, you see, and i've
filed the hammers maybe 1mm or so, and adjusted letoff, but the hammers now
have a "blocking" feeling (blocking against the string if you know what i
mean). i used the 1/8th 1/16th inch magnetic strips from Schaff or Pianotek as
a good place to start for letoff and tried to graduate it from 1/8-1/16.
<BR><BR>i'm wondering if i've set letoff too close. it's on a teacher's piano,
so i'm thinking kids who play lightly might notice it more,
too.<BR><BR>help?<BR><BR>daniel carlton<BR></BLOCKQUOTE></BODY></HTML>
