crown radius than a basketball, and a bridge is only 32 or 35 mm wide. So I
do suppose that the ribbed soundboard panel and bridge itself will conform
quite readily to the very slightly mis-matched straight bridge and curved
soundboard panel. The tenor end will bend enough (what, maybe 1 mm) and the
treble section of the bridge can have a top whose plane is not quite
parallel to the plane of the bridge bottom/panel top interface. Bottom line:
any difference is close to or wholly within common woodworking error and
completely negated by the flexibility of the woods.

That's pretty much it. I think my soundboard designs have as much crown in
them as anybodies. Considerably more than most. Still the (usually flat)
bridges lay down quite nicely.
