The finite life of wood grain

[Delwin D Fandrich]

David, 

If you have access to them you might go back and review the Journal articles
I've written on the subject. They can be found in these issues:
- The Mechanics & Strength of Wood & Wood Structures Part 1-Basic Mechanics
(April, 1996)
- The Mechanics & Strength of Wood & Wood Structures Part II (June, 1996)
- Soundboard Damage Part I - A Guide to Sound-board Cracks & Other Maladies
(December, 1997)
- Soundboard Damage Part II - A Guide To Sound-board Cracks & Other Maladies
(January, 1998)
- Soundboard Damage Part III - A Guide to Sound-board Cracks & Other Maladies
(February, 1998)

Not much has changed since they were written.

| Subject: The finite life of wood grain
|
| 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.
