There are many factors to consider when deciding what type of wood to use for a project. One of the most important is the workability of the wood: the way in which it responds when worked by hand or tools, the quality of the grain, and how it responds to adhesives and finishes. When the workability of wood is high, it offers a lower resistance when cutting and has a diminished blunting effect on tools. Highly workable wood is easier to manipulate into desired forms. If the wood grain is straight and even, it will be much easier to create strong and durable glued joints. Additionally, it will help protect the wood from splitting when nailed or screwed. Coarse grains require a lengthy process of filing and rubbing down the grain to produce a smooth result.
Particleboard is a manufactured wood product composed of sawdust, wood chips or wood shavings mixed with a resin. This concoction is layered, compressed, subjected to heat and cut to shape, resulting in a sheet material that can be used for a variety of things. It’s often used as shelving or as an underlayment for carpet. Plastic laminate may be applied to both sides to create a product that can be used to create everything from furniture to cabinets to wall paneling. Head into IKEA and you’ll find acres of particleboard.
Historically, woodworkers relied upon the woods native to their region, until transportation and trade innovations made more exotic woods available to the craftsman. Woods are typically sorted into three basic types: hardwoods typified by tight grain and derived from broadleaf trees, softwoods from coniferous trees, and man-made materials such as plywood and MDF.
Woodworkers set up, operate, and tend all types of woodworking machines, such as saws, milling machines, drill presses, lathes, shapers, routers, sanders, planers, and wood-fastening machines. Operators set up the equipment, cut and shape wooden parts, and verify dimensions, using a template, caliper, and rule. After the parts are machined, woodworkers add fasteners and adhesives and connect the parts to form an assembled unit. They also install hardware, such as pulls and drawer slides, and fit specialty products for glass, metal trims, electrical components, and stone. Finally, workers sand, stain, and, if necessary, coat the wood product with a sealer or topcoats, such as a lacquer or varnish.
When cutting full sheets with my circular saw, I use plastic shelving units as sawhorses. The height is just right and by using three of them, I can make cuts in any direction and the plywood is fully supported. And because the shelving units are made of plastic, I can cut right into them without worrying that they’ll damage my saw blade. Plastic shelves are available for $20 at home centers. — John Tinger.
