In the O picture it's more instructive to see the bridge layout over the actual rib structure. You can see that the angle of the rib to the board grain getting steeper & the ribs fanning to stay paralell with the bridge. It's plain to see just how much chorter & stiffer the longest ribs were & now are. Ron N. & O your comments about the tone getting stronger in the second half of the tone envelope are right on. The bridge has also been moved back at the top treble so that the note 88 could get a 50 mm string length increasing tension & power. This is sop on all redo. ON the A I even ground the plate. The original string length on the A was shockingly short at about 46mm & was changed to 54mm at 88 Dale Erwin Erwins Pianos Restorations 4721 Parker Rd.
