Choosing a Wood Sanding Machine

Whether you’re a professional woodworker or a do-it-yourselfer, the right wood sanding machine makes it much easier to achieve smooth results on your new furniture or vintage finds.wood sanding machine You can use a power sander to remove paint from an old table, sand down a rough patch of wood or smooth the surface of a hardwood floor for refinishing. The best sanders come in a variety of sizes and shapes to match your project, from handheld models for sanding in tight corners to long belt sanding machines that can work on large surfaces.

The wood sanding machine is one of the most essential power tools in any toolbox, and while it’s not the only way to smooth and level wood, you can’t find many carpenters or DIYers without one in their arsenal. Handheld sanding blocks are a great choice for a quick sand job and will also make the process go faster than using a power sander, but if you’re working on a larger project or want to speed up the job, a belt sander is the best option.

These machines come in a variety of sizes and styles, with choices including bench, hand-held and even robotic models. Some are even electric-powered. Most come with a dust bag that collects coarser-grit abrasives, but you may choose to upgrade to a vacuum hose and shop-vacuum system for even less messy sanding.

The main thing to consider when choosing a sander is the size of the abrasive pad or disc you will be using with it, which determines the type and amount of material the sander will remove from your project. You can purchase abrasives in belts that are either 3" to 4" wide and 18" to 24" long or sandpaper pads that are 9"x11" rectangular sheets you can cut into half, thirds or quarters. Larger tools can also accept sandpaper discs with 7" or 8" diameters.

Sanding machines can be very dangerous, so be sure to follow safety guidelines. Most importantly, wear hearing protection and don’t breathe the dust—it’s bad for you! It’s also important to unplug the machine when changing or emptying the dust bag. And never re-plug a belt sander until it is completely dry, which can cause gouges on the wood beneath (photo, left).

As you sand, move the sander in the direction of the grain. This will minimize visible scratches and give your woodwork a more professional look. It’s not always easy to see which way the grain runs on a piece of wood, but you can usually tell by gently sliding your thumbnail across the surface. If it “catches” on the tiny ridges of the grain, you’re going against it. It’s also a good idea to sand with the grain when applying a finish to protect the wood from damage and prolong its lifespan. This will prevent the finish from peeling or flaking. It will also help the finish adhere to the wood more effectively, giving it a longer life and a better-looking finished product.
