<DIV><BR>I usually apply the epoxy while I am installing the new
pins. After pulling pins and renotching the bridge, I mix up =
a small
amount of epoxy in a cup. Using piece of piano wire, I swab the =
holes with
the epoxy, dip the end of the pin in and insert it into the hole. =
The
epoxy oozes around so periodically I take an acid brush, dip it lightly =
into
lacquer thinner and brush the overflow down into the notches and across =
the
bridge top. </DIV>

<DIV><FONT color=#800080>No claims of expertice on my end, but this is =
exactly
the way I have done it also. Seems to work well.</FONT><BR></DIV>
<DIV> > For starters, I be careful not to put more epoxy in the =
pin hole
than <BR>> you were absolutely certain was going to make a =
gap-filling film
<BR>> between the (say) .075 pin and the .076 hole.</DIV>
<DIV> </DIV>
<DIV><FONT color=#800080>This brings up an interesting question. =
Best to
redrill and go up a pin size? Or to use the original pin size. I =
have gone
original size, and there was a fair bit of slop in the fit between hole =
and pin
(hammering pin in was not needed - pin just slid right it - maybe one =
tap to
seat). I wonder what the ramifications of that will be in the long
run?</FONT></DIV>
<DIV><BR>> We all have the mental picture of underground fissures in =
the
bridge <BR>> root, running from hole to hole, and an accompanying =
picture of
a <BR>> hungry-man sized dose of epoxy being pumped through the =
system of
<BR>> cracks as the pin is being driven into the hole. But in most =
<BR>>
instances, do we know just how extensive that maze of subterranean =
<BR>>
cracks is, and how much epoxy (above and beyond the amount necessary =
<BR>>
for the gap filling film) we'll need in the pin holes?</DIV>
<DIV> </DIV>
<DIV><FONT color=#800080>I have had a few that while hammering one =
bridge pin
in, you get a gusher of epoxy squirting out another pin hole. These were =
on
kinda junky pianos. I suspect that if this were a fine piano, one =
might
want to think twice about the overall integrity of the bridge if
you observed this happening. </FONT></DIV>
