Fine, Whatever. Let's not beat the dead horse further it's disrespectful to the horse. Dale We've been through this again and again and again on this list, nd my opinion ( which will be ridiculed by some here, but I have no interest in urther defending ) is that old wood that has been in decent reasonably clean, dry ) environments is acoustically superior. ( As in: "Rich" and "Warm" sounding. ) But this superior resonance can not be expressed, when the crown has mploded. I'm doing my first full soundboard recrowning according to a new method ( ot yet discussed here ) and may report the results.

This goes for all types of soundboard constructions. Wood that is subjected to seasonal climate changes that are sufficiently large is going to deteriorate no matter what the application. Wood that is in stable enough conditions will last a very long time indeed. We see many 100 year old instruments, particularly Steinways that have very fine functioning soundboards. Full of life and punch, no=0 D so-called killer octave, lovely response and lots of projection power. The compression damage argument when matched up with the basic RC&S philosophy gets shot in its foot. A panel may indeed be very much reduced in size cross grain compared to its original size due to permanent compression set, but when you dont rely on compression to begin with to build a panel.. then this fact is by definition a plus. Nothing about the permanent compression set inhibits the panel from being re-used thus. Only folks willingness to re-process an old soundboard does. I can refer to a discussion on the matter where Delwin Fandrich himself says exactly this in an exchange between André, myself, and Del about 8 years ago now. There is also the subject of how well wood is seasoned before taken into use. There are many 3-400 year old houses around here. Small houses made completely of wood. Mite damage is really the major problem. But those that escaped that and were otherwise taken reasonably good care of are in very fine shape. I have on the other hand 20 year old siding on my 300 year old house that has developed wood rot in several places. I've re-painted every 3 years, done all the stuff you are supposed to do but the stuff just cant match siding that was / is on houses that is from the turn of the last century. We see newer wood constructed hou ses (from the 60's onwards) developing serious structural problems all the time around here. Cheers RicB This is a curious question directed toward Dale Erwin and other soundboard people. Would it be fair to say that the majority of soundboards die after, say, 80 to 100 years? If that's true, then what's the major reason? Is it climate, or the simple fact that the board has been under pressure, or both of the the above? Also, this "death" is at the cellular / granular level, right? So then "re-crowning" would be about as useful as putting new chrome on a car with a destroyed chassis, eh? (Sorry if this is a dead horse already thoroughly beaten.) Thanks, and thank you again, Dale, for a great talk in Chicago. David David B.
