coating so it’s just flat again with very fine paper, ready for
refinishing—I don’t use DAG but leave the bridge top natural
wood. I try to avoid getting the epoxy in the bridge pin holes and I take
a toothpick to kind of ream the holes of any excess epoxy before it
cures. A thin coat of epoxy takes quite awhile to cure so there’s
plenty of time. </span></font></p>

is necessary if you are careful. The idea of using the CA, if it works as
well, is to avoid this particular problem since the thin CA won’t build
up. Also, it will presumably wick itself deeper into the wood—or,
at least, that’s what I’m wondering.</span></font></p>

Jsut curious. are you then pinning it before the epoxy dries or
while it's wet. If wet isn't that a bit of a sticky wicket to get it done
before things begin to set.<br>
If dry then the pin holes require some reaming....Yes? Are you coating
the top with dag or leaving it natural<br>
I like this idea .....all but the sticky wicket part..<br>
