---------------------- multipart/alternative attachment Terry Quite sure as I've seen this reverse crown design probably a dozen or = so times of various makers. It is one of those things that is just too intentional and symmetrical t= o simply be a collapsed board. I have yet to run across one that didn't s= ound more musical than most pianos ever dreamed of being. Julius Bauer, B= ecker Bros. ,Steck and others I can't recall the names of right now. The = boards were also not split up from the tension instead of compression as = one might think.

Do you know if this configuration was the intent of the desi= gner & manufacturer? Just curious.

I rebuilt a George Steck 6 ft. gra= nd last year with this arrangement. When I first encountered the piano th= e sound was absolutely magic. The sustain just floated for what seemed li= ke forever .

A bit more time consuming to string but what a gem. I keep finding all= kinds of sound board conditions and configurations which aren't supposed= to work that do and others that should that don't! =20 I have to figure that the weight of the Big Brass agraffes also contri= buted to the impedance properties of the board probably a sustain enhanci= ng dynamic. =20 Ain't life interestin---Dale Erwin----- ----- From: Tom DriscollSent: Sunday, November 18, 2001 6:28 AM To: pianotech@ptg.org Subject: Hallet Davis bridge agraffes =20 Enclosed photo of Hallet Davis Grand referenced by Phil Ford in recent discussion of bridge agraffes.
