User Tips: How to Sand?

If you are a beginner in doing wood works, a question may twirl in your mind on ‘What is a Belt Sander Used for?’ In this article, we try to guide you on its usability and some key notion of using belt sanders. First, if you are using a power sander especially a belt sander, remember to avoid underdoing or overdoing it. Underdoing it will take you forever to complete the sanding and overdoing it might ruin your project.

The primary task before using your belt sander is to install the loopy-sheet between the wheels. Unlock the tension lever or hold the spring in a spring loaded model to slip in the new belt. Make sure to watch the arrow sign on the belt before installing it, and then release the lever or spring to fit the belt within the rolls.

Next, turn the sander on to see if the belt rubs or slips from its position. If it does make sure to adjust the tracking knob and bring the belt in a central position on the wheels. Finally, when you start sanding on your project keep the sander move in an even pace keeping up with its linear movement.

Do not press down on your sander it will create inconsistency on your wooden surface. Move your belt sander in a zigzag motion and overlap your sanding area. If you are leveling a narrow wood piece, try to stay straight with your sanding. For doing works on several narrow woods you can just place them altogether to sand the edges at once.

Use variable speed at a controllable speed or at minimum to avoid over sanding.

Clean up your work area and remove the debris from the surface. The stuck debris will cause gouges on your project.

Keep the sander moving until your work piece has reached the required smoothness. Sand it the wood with an even pressure and minimal speed. Inconsistent movement on the surface may create imperfection on the work surface.

However, having a belt sander is a great addition in your utility tools to give your project a smooth and glossy finishing as a woodcrafter or DIY’s.


Belt Sanders are safe and handy tools for using.  However, it is wise to be precautious on some things to avoid uncertainties.

  • Wear a safety mask to avoid breathing in the sand powder into your lung.
  • Cover your eyes with a protection glass while sanding your wood or hard cardboard. While doing the sanding, the sandpaper materials and sand dust can get into your eyes.
  • Use a hearing cover to avoid the loud distraction of the sander.
  • Unplug the sander from the connection before changing your sandpaper or emptying your dust storage.
  • Do not rest your belt sanders on your work surface it can tip over and spoil your project.
  • If you use belt sanders on metal surface, blow out the dust with the inbuilt blower of the sander or vacuum it. The abrasive on the sand belt may cause spark while sanding and it can spread fire through the sand dust or the dust bag.
  • Remember to pull the trigger off before plugging it in. If the trigger of the belt sander is turned on, it can flip on your work piece and ruin it in seconds.
  • Secure your wooded piece, cardboard, or frame in a fixed position by clamping it with a table or make it stationary with something. Once you start sanding on your work piece it cannot move or slip from its position. If it does, it will ruin your work in the middle
