While in the case of a loose bridge pin where the space is very small CA seems to work fine (though I think epoxy is better assuming you have a way of delivering it) CA is not really designed for "gap filling" in spite of the label on the >> I suppose it depends on what you mean by "epoxy". I know that the stuff that comes in the tubes at the hardware store is NOT hard, even when set. While I wouldn't want to be hit with a chunk of it, when it comes to acoustical transmission, I don't think that stuff is very transparent. The West System resin that I have used, on the other hand, (actually, when I use it is ends up on both hands, face, shirt, and a foote, sometimes), seems to be much harder. It takes a day or so to get there, but the runners that I can peel off the glass jar snap much more cleanly than the usual epoxy mixes I have used. If you need to fill a gap with CA, a light packing of baking soda, first, and then wetting down with the water thin CA will make a small rock. Something about the matrix action of the soda's granules. Regards, Ed Foote RPT http://www.uk-piano.org/edfoote/index.html www.uk-piano.org/edfoote/well_tempered_piano.html
