>Ron, >Would gluing on an uncrowned long bridge not force some of the valuable >and available crown out of the rib/board assembly? >Owen Greyling, RPT Ontario, Canada No, because the bridge is curved. The curve lets a flat bridge lie down on the soundboard just like a crowned bridge. I tried it once to see what would happen. Laying a flat bridge root I had just made on one of my high crowned boards (temporarily screwed down in the piano, it fit the board contour very well. I then cut a crown in the root and positioned it back on the soundboard to see what difference it made. I couldn't see that there was any real difference, and couldn't have told you which bridge was which if I was looking at pictures of each sitting on the board. The crowned bridge didn't sound any different to me after stringing than flat bridges I had installed in other pianos. If crowning the long bridge makes a tonal difference, or supports crown in some manner, I certainly can't detect the difference with either my ears, or measurement. Ron N
