I bought several board of oak via Craigslist from a guy who is moving. They are apparently reclaimed from some sort of building and fairly old. Close to 40bd ft for $40, seemed like a good deal. Most of the boards have nail holes all along the length about an inch in from the edges, figure I can cut off that part if needed to get clear wood, or just fill them if it doesn't matter. A couple of the boards have large cracks or knots. There is one 12' long piece that's nice and clear with no holes. I am still quite inexperienced when it comes to choosing wood, was this a good find or no?
