Just because we know that the most significant measureable factor on soundboards is stress over time does not serve as proof that there are not other factors involved. You just posted that a 100 or so year old panel with new ribs "probably" would sound the same as a brand new panel in relation to Andre's posting. A direct consequence of this reasoning (and the above) is that we dont need new panels at all. Just rip out any old panel from an old birdcage wreck...glue it back into one piece and rib crown it with new ribs and it will sound good as new. I am sure the soundboard manufacturers will be very pleased at this notion. You show us, refere us to, quote, or in some other sense document the studies that conclusively show that there are no significant changes in the way sound and wood inter-relate as a result of wood ageing, or varnishing for that matter. When you do, you will no doubt end the discussion that has been raging about this for god knows how many years. Until you can do this...you reside in exactly the same place as those who declare other unsubstantiated ideas to be fact. No offence meant Del... but really... You want to put an end to all the "mystikk" surrounding this and other such subject matter... then you need to stop blowing your own magic smoke first. And for the last time... nobody is comparing Violins directly to pianos... the Violin examples are used in conjunction with wood ageing... not with differing stress situations. Until you prove that ageing of wood per se has no significance... then it will continue to be natural to use such examples. Science is science... treat it that way. This is beginning to remind me of those Doctors Ron Nossaman is on about all the time... grin Freindly regards. -- Richard Brekne RPT, N.P.T.F. Bergen, Norway mailto:rbrekne@broadpark.no
