This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment I discovered a couple interesting tidbits today on the web site of a = well-known NY piano manufacturer. The ribs (which I understand to be flat) on the soundboard "assure = strong and constant support of string down-bearing on the soundboard." = Interesting for a rib that doesn't even support its own panel-induced = curvature. But I guess here is how soundboard crown is maintained: "Rib ends are = hand-fitted into their mounting surfaces virtually locking in the = important soundboard crown." I suppose a "mounting surface" is the = notch? And this somehow "locks in" crown? Are they suggesting that the = bottom of the notches are angled upward toward the bridge and the rib is = glued to this perfectly fitted angled notch so that the rib forms a = curvature? Is that what's going on here? Terry Farrell ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
