<DIV><FONT face=Arial>Byron, I have several of these that i have
done. I will usually try to tune almost anything, the problem with a
lot of these is that the coils were tapped right on the plate and you sure hate
to pull them after they have set in pin tight for 20 years. I take my 1/4
driver that I use to install dampp-chasers, pull the action, get a three pound
hammer and turn it sideways, put the driver in the pinblock from underneath and
give a good whack. The pins will drive out fairly easily, the coil is off of the
plate, the CA will work, and you will feel a lot better about tuning a coil that
is up. In a half an hour you can pound out the entire piano, and it
is easier to do them all than piecemill. The process is quick with
really nothing to lose and you can save some pianos that would
probably just be discarded without it.</FONT></DIV>

<DIV><FONT face=Arial><EM>I have a customer with a John Brinsmead & Son
5'6"? grand, circa 1910 or so.<BR>The piano is not great but has been maintained
reasonably. The customer is<BR>not a player but likes the way it looks in her
house and would like it to be<BR>able to hold a tune. She, of course, wants to
do this as cheaply as<BR>possible. The pinblock is shot and evidently has been
so for over 20 years.<BR>Someone treated it with "Pin Tite" over 20 years ago.
I've searched through<BR>the archives and have found a bit of encouraging posts
about CA being<BR>somewhat effective on "Pin Tite" treated pinblocks.<BR><BR>
<BR><BR>However, the problem I see is that the pins have been driven in so the
coil<BR>sits right on the plate. There are also those felt bushings between the
coil<BR>and the plate but they are quite crusty and with a little bit of work
they<BR>can be removed. The pinblock is quite thick so the tuning pin holes do
not<BR>go all of the way through so it can't be treated from below. There
appears<BR>to be a tiny bit of "daylight" between the coil and the plate at the
front<BR>of the pin and it seems possible that I could get a smallish syringe
needle<BR>in the gap to treat with CA. <BR><BR> <BR><BR>My question is, has
anyone ever had a similar situation where they had such<BR>a tight access to
treat the pinblock? If so, how successful were you and<BR>what potential
pitfalls are there?<BR><BR> <BR><BR>Thanks,<BR><BR> <BR><BR>Byron
