I have read that Doug Fir is uniquely stable among woods in
that it expands and contracts equally in both the radial and
circumferential directions and so it is the only wood commonly
sold as dimensional lumber while still green (others will usually
be kiln dried to 12 % MC) However, I have seen Doug Fir boards
cup and uncup with variations in humidity, indicating to me
that this is not true.

Indeed, it is not true.

ever wanted to know about wood, and more.
