<DIV><FONT face=Arial size=2>David, I'm not sure I agree with =
you about
epoxy being harder than ca. I have used both ca and epoxy to fill rather =
small
cracks in soundboards. I don't recall, but I think the ca was the =
gap
filling one.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I would put masking tape on each side =
of the crack
and fill so that the filler would be tape thickness higher than the
wood.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I would then scrape to level the =
surface. It
was a pain to scrape the ca because it was so hard that it dulled my
scraper. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>That said, I think both ca and epoxy =
are wonderful
products and have many uses. There are also many opportunities to =
screw up
with them. DAMHIK.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It seems that ca and epoxy adhere to =
each other
very well. I know a tech that will seal the top of a crack with a =
white
(tinted) epoxy paste, then turn the piano on its back and fill the =
bottom with
ca. I don't know the thickness of the ca he uses. I think I =
would
prefer a thin epoxy on the bottom.</FONT></DIV>
