<DIV><FONT face=Arial size=2>Hi Calin,</FONT></DIV>
<DIV><FONT face=Arial size=2>Actually Hallet & Davis In the late =
1800's made
pianos ( upright for sure I have seen 3 ) that had agraffe on both =
string
termination points. The bass strings had a kurf in the side of the =
agraffe on
the bridge end and the agraff were drilled so that they alternated with =
a slight
angle up then down as the stringcame out of the agraffe. The one that I =
restrung
also dad the stickers pinned to the key and the action and keys came out =
as one
unit. Another interesting feature was the jack springs pulled the jack =
rather
than pushed it.</FONT></DIV>
<DIV><FONT face=Arial size=2>Oh yes, also the hammer flange had =
a screw to
tighten and adjust the friction on the center pin. We still have the =
piano at
the store , when it came in it looked like a dog had been chained to the =
legs.
She was battered and brused but now a beauty.</FONT></DIV>

<BR></BLOCKQUOTE><BR><BR>One of the very great developments of our =
business
here in Holland is the new front punching called "Grand Piano =
Punching".<BR>I
have worked for years on this and we now offer this punching world
wide.<BR>And why then is it so very nice one could ask?<BR>Because it =
has a
fantastic homogenous density, but at the same time it is not too =
hard.<BR>It
makes for a very sharp after touch, and thus for the sharpest =
regulation
possible.<BR>As I said, it took me years to get this together, and it =
is even
better than the Yamaha or Steinway punching because of its density and =
firmness.<BR><BR>I wrote about this before : after touch should be ± =
0,4 mm,
meaning that after drop, and after the landing of the hammer, we =
should be
able to move the hammer up 0,4 mm by <B><U>softly</U></B> pressing the =
key. If
you see no movement at all, you have no after touch. If you see a lot =
of
movement, your front punching is too soft or you have too much after =
touch....
which is it?<BR>That's why you need to make sure that before you start =
a
regulation, your front punching is of the right firmness.<BR><BR>I =
will
explain once more :<BR>A key is like a sea saw.<BR>Usually, we find an =
old car
tire under both sides of the sea saw to soften the impact. =
Nevertheless, a
little child sitting on the high end of the sea saw will bump upwards =
slightly
because of the impact at the lower end.<BR>Now, if we take away the =
tires, the
impact will be much harder and it will hurt the behind of the child =
coming
down, but it will also cause the other child to almost get airborne, =
because
the force of the impact is much stronger.<BR>That is the an analogy in =
regard
to a more firm front punching : It causes a more intense transfer of =
energy
and thereby creates a louder tone.<BR>Your regulation can be more =
precise,
thereby giving you the maximum tonal output.<BR><BR>I often ask a =
critical
technician or pianist to listen to a particular tone and to feel its =
touch. I
then exchange the front punching with our own front punching, and I =
ask the
same person to<BR>listen and feel again. They always are flabbergasted =
by the
result.<BR><BR>friendly greetings<BR>from<BR>André =
