color=#000000 size=2 FAMILY="SANSSERIF"><BR>I did this on a 110 =
year old Weber
grand with a mortised pin block, and it worked quite well. I shored up =
the
bottom of the pin block, and pored a small amount of impact resin in =
each hole
and then drove in a 2/0 pin in each hole. (in some cases, I was able =
to just
push the pin in with my fingers, because the holes had gotten so big). =
I used
impact resin back them because that was what I was familiar with. =
There are
now new epoxies that will do the same thing. You want a slow curing =
mixture,
because it takes time to put in the pins. Impact resin gives you about =
10
minutes to work with. So obviously, I only did a small section at a =
time. In
this case, the pin block also was delaminated, so in addition to =
filling the
cracks, the resin also filled the gaps between the lamination. To =
tighten the
gaps, I clamped the block with C claps in about four or five places. =
<BR><BR>I
let this sit for about 3 days. I removed the 2/0 pins, and then strung =
the
piano with 3/0 pins. Some of the resin will come out on top of the =
block. So
when yo're all done, you can chisel off some of the excess, but it =
will deface
the top of the block. If you have an open face block, you probably =
would want
to put a nice piece of veneer on the top of the block. All you need to =
do is
dimple the holes. A tuning pin will drive right through the veneer. =
<BR><BR>I
did this about 12 years ago, and the piano is doing fine. There will =
be a
little different feeling to the pins. They don't turn like they do in =
wood,
but that is a problem only the tuner has to deal with. There is enough =
torque
to hold the string. <BR><BR>Hope this is enough information. If you =
need more,
just ask. <BR><BR>Wim <BR></BLOCKQUOTE></FONT></FONT></BODY></HTML>
