Despite the abundance of plastics, metals, and other materials, wood products continue to be an important part of our daily lives. Woodworkers make wood products from lumber and synthetic wood materials. Many of these products, including most furniture, kitchen cabinets, and musical instruments, are mass produced. Other products are custom made from architectural designs and drawings.
Some woodworkers obtain their skills by taking courses at technical schools or community colleges. Others attend universities that offer training in wood technology, furniture manufacturing, wood engineering, and production management. These programs prepare students for jobs in production, supervision, engineering, and management, and are becoming increasingly important as woodworking technology advances.
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.
A while back, I reached for my two containers of epoxy and noticed that the resin in one container had crystallized exactly like honey that’s been in the cupboard too long. The solution is exactly the same too: Set the container in a bowl of hot tap water. After about 15 minutes, I emptied the container and refilled it with hot water. After about a half hour, the epoxy regained its normal consistency. Good as new! — Ken Holte
