Is it possible to find 2×4's in clear pine or southern yellow pine with no knots or at most a few pin knots? It is readily available in 1x, but I can't find it in 2x. I have a project that requires the wood surfaces to be smooth (sliding fit).
A great way to do it is to buy 2×12s and rip the edge off. You get two of them, quartersawn, and yellow pine. That s the goods there. Cheap, and effective.
