FWIW, the Knabe = upright that I yanked apart and appeared to have a crown cut into the ribs had ribs = that were wider than tall. Regarding the crowning nature of your Packard - you = state that <EM>"Packard was rib crowned there is no doubt: the contour is readily = visually observed as cut into the ribs themselves."</EM> How can you determine = that? If the rib is curved, could it still not be from panel compression? You may = well be correct, but I just don't see how one could be so sure.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Terry Farrell</FONT></DIV> <DIV><FONT face=Arial><BR><FONT size=2></FONT></FONT></DIV><FONT = face=Arial size=2>> Thank you, Terry, for the informative answer.<BR>>      Actually, no, I remember not from whence = the<BR>> statement originated: only that somewhere in the<BR>> barrage of info = on this list it was stated that a<BR>> rib-crowned board should have ribs = taller in<BR>> cross-section than wide. And that any piano with wide = <BR>> ( rather than tall ) ribs is inherently CC. That this<BR>> Packard was = rib crowned there is no doubt: the contour<BR>> is readily visually = observed as cut into the ribs<BR>> themselves. Also that it has an extremely = full, rich,<BR>> round tone there is no doubt, though the damage to = it<BR>> is significant ( it lived beneath an air-conditioner<BR>> and the whole = board is white with water-damaged<BR>> shellac. ) And the aforementioned = cracks. Quite a<BR>> testimony to RC construction, I do believe !!!<BR>>      Thummmmmmmmmmmmm<BR></FONT></BODY></HTML>
