Since I was transplanted here in Texas in the mid 70's from the upper
Midwest, I've always been amazed at the 'usual' kinds of wood used here
for construction. Like Ed, I'm not an expert, but what is typically
called Southern Pine is some of the worst lumber I've ever worked with,
while Douglas Fir some of the best (but darn hard to find and very $$).
My boss once bought several studs to add a short wall in the studio. He
bought the lumber on a Saturday and left it in a hot van till Monday.
On Monday I heard him cussing--that wood had turned every way but
straight! My personal feelings are that most woods grown in wet
Southern climates grows too fast and simply contains too much water.
Since you can harvest the trees quicker there's a fair amount of it
around. When the wood finally dries out (after several years) it
shrinks, twists and eventually get brittle.
That being said, near a former studio location, was an antique dealer
who received crated items. Some of my modules are made from 'dumpster
diving' and I'm proud of it!
