For many of us, the moment we learned that a 2×4 board is actually 1.5 inches x 3.5 inches was simply mind-blowing. The reason for this apparent contradiction is that the board has been planed down to eliminate irregularities. At one point, many years ago, 2x4s actually were 2 inches x 4 inches, but their rough surfaces made them difficult to stock and handle. The old terms, such as 2×4 or 4×4, are still used, and are known as the “nominal” size of the board. These nominal sizes are used because they are easier to say and they stick to tradition. Now, thanks to a lawsuit, most big box stores list the nominal and actual sizes of lumber.
Another important factor to be considered is the durability of the wood, especially in regards to moisture. If the finished project will be exposed to moisture (e.g. outdoor projects) or high humidity or condensation (e.g. in kitchens or bathrooms), then the wood needs to be especially durable in order to prevent rot. Because of their oily qualities, many tropical hardwoods such as teak and mahogany are popular for such applications.
Hard to determine which stain you need in that bespattered collection of cans? An easy-to-make “stain index,” courtesy of reader Bob Jacek, solves the problem. Section off boards of your favorite woods into squares with masking tape, and apply the different stains across the width of each wood type (pine, oak, birch, etc.). When the stains are dry, brush on lengthwise your regular ﬁnishes—polyurethane, water-based polyurethane, oil, orange shellac, etc. You’ll be able to tell how each stain looks with each ﬁnish. Label each one. Use both sides of each board, and you’ll have a wooden encyclopedia of stain and ﬁnish combinations. Plus: How to stain wood evenly.
