<DIV><FONT size=2>Hey Keith,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I have lately been setting "no aftertouch" on a =
few notes
in the piano with a weight that John Hartman has dubbed the "third =
hand".
Stack punchings on the frontrail pin of the key in question until it =
just lets
off when this weight is very gently lowered onto it. It might even =
letoff
a second or two after you have completely released the weight. =
When you
get to the bench do whatever you have to to duplicate this feat, =
tape
shims to the front rail or glides or turn down glides or any
combination. I have some wood shims that taper down to =
nothing. If needed they are inserted under the frontrail until the =
deed
occurs and then marked and labeled (also mark frontrail). Locate =
the
action in the same place every time on your bench.( The height of letoff =
is
unimportant in the piano and on the bench, you can set it in the piano =
if you
want just don't change it after removing action until you have =
set up
your bench ) You might need to clamp down the front rail at =
the two
ends to get everything working, then aftertouch set on the bench =
will be
<U>very</U> close. No need to measure anything. My bench is =
flat
marble, not because I'm that anal (well actually I can be) but =
because I
used to install the stuff. You don't need a bench that flat. =
Some
actions need almost an eighth inch under the front rail to duplicate =
what is
happening in the piano. Steinway frames are stiff enough that they =
can be
duplicated with three notes. (Well the old ones anyway) If =
you have
more of a Yamaha style set a couple more notes. Good =
Luck.</FONT></DIV>

<DIV><FONT face=Arial size=2>I just replaced the brackets on a =
Y&C. I
brought it home so I could do it on a bench that was the right height. =
I set
my boards to string height and roughed in blow distance and jack
position( 1/4" out). Started through letoff and the sharp dip was =
about right
but the whites, the dip was so shallow the hammer rise was shy of =
letoff by
1/2". I know you can't set dip out of the piano and realized I should =
have
measured the dip because now I'm wondering if the tech that wound all =
the
adjustments out, messed with the dip so as not to break the jack off =
against
the stop. In this case, the drop screws came up 3 turns and the let =
off
buttons 5 turns. So now I'm thinking I should have shimmed the balance =
rail up
to get enough dip so I could set let off. My aching back tells me =
I'm
doing way too much work in the piano. It would be so nice to duplicate =
the
bedding, so the amount of refinement in the piano was minimized. Dale
Erwin said I could take sample dip reading of every C and shim =
the rails
to duplicate the dip. </FONT></DIV>
<DIV><FONT face=Arial size=2>Does anybody have any other methods? =
Would it be
better to take the sample dip readings at the notes next to the =
bedding
bolts.</FONT></DIV>
