<DIV> Interesting & true. I also agree with your point of view.
However I have recrowned an upright boards without taking it out of the=
piano & it sounded unbelievably great. How long it last & is viable =
is a
guess but it will probably out live me. I posted this before & it's in t=
he
archives probably under recrowning. duh Dale</DIV>

one thing that gets me to NOT want to do a re-ribbing of an olde <BR>>
board, is the fact that wood does age. Forget the compression factor <BR>&=

for now. Let's just consider this: In the aging process of wood, it <BR>&g=
t;
loses it's cellular cohesion/bonding. At some point, this aging <BR>>
process creates what is known as Brash Failure. If wood is kept in a <BR>&=
gt;
consistant environment, it will eventually turn to stone, (ie <BR>>
petrify). The Brash Failure occurs about half way to the petriying
stage.<BR>> Most of us have run into the action w/parts that defy repai=

These <BR>> actions are in the first stages of Brash Failure. The best =
way
to <BR>> explain how the wood reacts is: a new shank/dowel, when broken=
will <BR>> splinter. One with Brash Failure will break cleanly, as if i=
t
were <BR>> sawn. I've seen this problem on parts that were less than
50years <BR>> olde, so there's really no way of telling when this will
occur.<BR>> So, back to the boards....I feel that there is no way of
knowing how <BR>> much more time the wood, of the sound board will have=
, so
I'm very <BR>> reluctant to re-rib a board, even though it is an intrig=

<BR>> idea/technique. I think, that if I'm going to go to all the troub=

to <BR>> take a board out, then I'll improve on what was there original=

if I <BR>> can.<BR>> Best Regards,<BR>> Joe Garrett, R.P.T.<BR>&g=
