Recently, I was at the home center, trying to find a really straight 2x4, and knowing that even a straight 2x4 might bow or twist when I get it back to the shop, or worse yet, after it's machined it to its final dimensions. Anyway, I wasn't having much luck.
Then I remembered one way the guys in the Woodsmith shop get dimensionally stable lumber is to start with a wider board like a 2x8 or 2x10 that has a 2"- to 4"-wide strip of straight-grained material near each edge. They rip off the edges to get at the good stuff.
