In the previous article we looked at some commonly asked questions, and answered them. Here are some more frequently asked questions and the answers to them.

Question 1: What is the “nominal size” of a piece of wood, and why is the listed nominal size smaller than the actual size of the wood being bought?What is “nominal size” and why is it smaller than the actual size of the wood I bought?

Answer: A board’s “nominal size” is calculated based on the rough size of the board before it is dried and planed, taking into account any shrinkage. It is normal for a board to shrink when it is dried out and planed smooth, and this will make it thinner and smaller than the size you see when you are buying it. The nominal size is an estimate based on typical shrinkage.


Question 2: What does “dimensional lumber” mean and what does “S4S” refer to?

Answer: Dimensional lumber is a piece of lumber that has been trimmed down to a standard depth and width. These dimensions are specified in inches. Common sizes include the famous 2 x 4 (also known as two-by-four), 2 x 6 and 4 x 4. The term S4S means “surfaced on 4 sides. Most dimensional lumber is sold S4S, or finished, and it is labelled according to its nominal size.


Question 3: I have purchased a bandsaw blade, but I noticed that when I tried to install it the teeth were not facing up. They were facing down. What is wrong with the blade?

Answer: It is not uncommon for technicians to forget to turn the blade the right way around after it is welded. In addition, sometimes when people uncoil a blade they accidentally flip it inside out. The good news is that it is easy to flip the blade so that the teeth are the right way around so that you can mount it properly on the bandsaw.
