What is a Belt Sander Used for?

Power sanders can be real time savers on your projects if you use them right. When you’re using any power sander there are two things to avoid; underdoing it and overdoing it.

A belt sander spins looped sheets of sandpaper-like tank treads. It’s a powerful tool and it’s best for rough work. You need to know what you’re doing.

Are you aware of some of the uses for belt sanders? Here are some of the uses.

Removing Old Paint, Varnish or Stain

Removing stain can be time-consuming, but this is where belt sanders come to place. Gouges happen when the belt or sandpaper gets gummed up with dust, grit pitch from the wood and glue.

Use clean belts and avoid sandpaper grits more beautiful than 120. Keep the sander moving at all times, so you don’t like sand in depression and keep it even on the surface, so you don’t create dips, bowls or other imperfections.

Broad Areas

A belt sander can also be used for sanding large projects like solid doors or tabletops. It works so quickly and you can quickly make a mess of your project if you’re not careful.

If your sander has a variable speed, dial it down for delicate work. Take care not to round off the edge of your piece by tilting the sander. It helps to use a scrap of wood as a stop at the edge of your project.

Rough or Raw Surfaces

The belt sander would be your choice for that first pass on a rough surface. It’s great for rough work, but it can be hard to get the hang of, so it’s not recommended for beginners.

It isn’t essential unless you find yourself with a lot of these types of tasks. You can also use it to even out cupped boards or to take down a saw cut to your scribed mark.

How to Use Them

To install the sandpaper belt, you’ll unlock the tension between the two wheels. Flip the tension lever or on a spring-loaded model, push the front roller against your work surface.

Slip the new belt on with the arrows pointed in the direction of the spin and flipped the release to put the tension back on the belt. Turn it on to see if the belt rubs or slips. If it does, adjust the tracking knob to keep the belt centered.

Keep the sander moving at an even smooth pace and don’t press down on the sander. Let it do the work move in a zigzag motion. Let the sander go past the edge of the piece and overlap your next pass slightly.

Note: When using a belt sander, always wear eye protection, hearing protection, and a dust mask. Unplug the tool before changing the pads or emptying the dust collector so you don’t hit the trigger accidentally. Check the trigger to be sure it’s off before plugging it in and never rest the sander on your project.
