<DIV><FONT face=Arial>Happy to help if I can Daniel. First of all, it is likely
that it will be difficult at best to set the letoff accurately on each note to
within 1/16 or less of an inch. The letoff punchings on an older piano (I'm
assuming this is a some-decades-old piano) are going to be deformed and you're
just not going to be able to accurately and consistently taper letoff from 1/8
inch in the bass to 1/16 inch in the treble. </FONT></DIV>

<DIV><FONT face=Arial>To measure what letoff you have, the easiest thing to do
is just do it with your strips and check it by eye. But if that isn't working
for you, try the following: Get a substantial weight that you can set on a key
to make it go down and through letoff. Then get a few pieces of wood or
whatever that are maybe 1/16, 1/8, 3/16 and 1/4 inch thick. Hold the various
thicknesses of wood on the string where the hammer strikes and let the weight
depress the key. See at what distance the hammer blocks and at what distance the
hammer/key goes through letoff. That should answer your question.</FONT></DIV>

<DIV style="FONT: 10pt arial">----- Original Message ----- </DIV>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
