Thanks Ron, We were taught to dry the board to about 10%, plus cut crown into the ribs, then the press, with the natural bend afforded by the calculable give of yellow pine under the pneumatic stress gave us a lovely predictable crown. The pianos speak beautifully. We only got to do two, a Steinway and a Baldwin. We seem to get a small amount of compression ridge in the Baldwin in the summer. The Steinway, I'm ashamed to say, is not maintained regularly. We would do more soundboards, but haven't really run into the right conditions. Also, I moved most of my operation to the home. I haven't room for the press here, it's at Frank Bissol's, PTG Associate, about 15 miles north. Roger Hayden, RPT Clarks Summit, PA
