That sounds reasonable enough to me. I think that qualifies you as a bonified
expert. At least that much or less seems to qualifiy a lot other folks as
such. We'll leave it there for now :)

I have it on dietic authority that wood looses its reactionary behavior to
climatic and anti climatice variations in ambient atmospheric conditions. I
thought that was the same thing.

Ok... but .... is that a good idea or not ? I mean... vhat dost that doeth to
its qualities that we are interested in... or easier said... can ya still
make a good sounding soundboard out of it ? Could you use such "wood" to make
a more stable keyframe ? What about such material for a bridge ?

Just curious....as usual.. and a bit more then usually annoyed at the curling
key frame syndrome.
