List, I am currently working on rebuilding my own little piano to gain some experience, and have a question about improving the crown, function of the soundboard. I had heard of shimming up the SB from underneath, prior to shimming, or doing anything else on top (Bridge repairs, etc.), in hope that by doing these repairs while the board was shimmed up, they might act to improve the crown, even a very little bit. My question is about flowing epoxy over the surface of the board, as was discussed here a while back, and I'm wondering what you all think about having the board wedged up & flowing on epoxy. My concern is about what may happen when the wedges are removed - cracked epoxy?!?!? What say you? William R. Monroe
