hi all,

i have found a web site that have huge database about wood properties and requested it from them. unfortunaty they will not provide it to me (which is undertandable). but here is the answer from them.

> Mansonia
> Turkey Oak
> Makore
> Movingui

inksoup, check out the USDA Wood Handbook, which you can see on the Forest Products Laboratory website. It's the bible for us wood folks. Free to download by chapter.

OK, what is MOE and MOR. And why don't we have all them woods at the local store.

Chinaberry? I have actually wondered about that lately. Chinaberry was popular when I was a kid but don't see much of it any more.

re: razorback
MOE = modulus of elasticity
MOR = modulus of rupture
