"you need to leave some epoxy in the gap. You don’t want to epoxy-starve the
joint."?<BR><BR>I found a source for Western System Epoxy handy repair set
including that filler here in Germany. Good to know, I will try it perhaps one
day, but not with that Kawai. I told the customer to ask a collegue who has 7
pianotechs working for his shop: 4 on master level, 2 with certificate of
apprenticeship and one apprentice, and they have a huge workshop. I don´t do
repairs with woodwork anymore, just tuning, small repairs and selling pianos.
But in this case it probably would have been easier to order a new brigde from
Kawai which fits perfectly without any adjusting: just installing and it
fits.<BR><BR>Gregor</SPAN></FONT><FONT face=Tahoma size=2><SPAN

style="FONT-SIZE: 12pt; FONT-FAMILY: Arial">Epoxy repairs for a situation as
you describe can yield very good results. Sometimes the crack opens up a
fair bit – you’ll want to clamp it back into position – not to clamp in the
traditional sense, but rather to simply position the parts in their original
orientation – you need to leave some epoxy in the gap. You don’t want to
epoxy-starve the joint.</SPAN></FONT><FONT face=Tahoma size=2><SPAN

High-Density Filler<BR>404 High-Density filler is a thickening additive

gap filling where maximum<BR>strength is necessary. Color:

style="FONT-FAMILY: Arial">You can either push the bridge pins into
the uncured epoxy, tidy up and be done with it, or, for a neater, more
exacting job, you can epoxy the gap and then drill bridge pin holes after the
epoxy hardens. I have found that if cosmetic considerations are not paramount,
I apply the epoxy, clamp together until the wood is close to original
dimension, clean off epoxy squeeze out (acetone) - at that point you will be
able to see the outline of the original pin holes - push pins in place - the
wood will have been drawn together enough to hold the pin in its original
position - and then level off and clean up the little bit of epoxy that
squeezes out of the holes as you push the pin in place. Wait a day or two for
the epoxy to completely cure, go back and install bass
strings.</SPAN></FONT><FONT face=Tahoma size=2><SPAN

archieves but I did not really find what I was looking for: does Epoxy work
even for bigger gaps?<BR><BR>I wanted to tune a Kawai CE-11 upright
yesterday but the bass bridge looked horrible: a long gap which affected 9
notes. The gap started at the upper pin row and the pins were vertical. Some
strings rattled at the pins. The gap expanded up to <st1:metricconverter
w:st="on" ProductID="4 mm">4 mm</st1:metricconverter> above the upper pin
row. I did not try but I could imagine that I could have pulled out some
pins without using pliers.<BR><BR>First at all: I never worked with Epoxy.
My first thought was to pull out the pins, fill the gap with epoxy and drill
new holes for new pins. Could that work or is such a gap too much for Epoxy?
The bridge is made of one piece of wood, no cap.<BR><BR>I was shocked about
such a gap in a Kawai from 1992 (no grey market import): no floor heating,
no air con and no heater near by the piano. And I don´t live in an area with
huge differences in the climate. Very strange. That damage is a pitty
because everything else in this piano was in a pretty good condition. But
making a new bridge would be definitely too expensive including transports
from the second floor into a workshop and back to the
customer.<BR><BR>Gregor<o:p></o:p></SPAN></FONT></P>
