Essential Things To Know About Belt Disc Sanders

How Belt Sanders Work?

The heart of a belt sander is an electric motor designed to turn two drums that accept uninterrupted loops of sanding belts (reinforced abrasive cloth) over them. As the motor powers the rear drum, the front drum starts spinning freely. You can slip the belt onto the pair of drums with the help of a tension-release lever. Most sanders include a knob for tracking adjustment to enable the operator to turn to center the sanding belt.

Being capable of putting a brute action on wood, a belt sander proves to be ideal for use at the beginning of a sanding project. Sometimes, woodworkers prefer these heavy tools as they want some materials removed very quickly. This tools yields even greater results when you use it for removing wood paints or deep finishes. Fit it with a piece of fine grit sand paper, and getting a smooth surface will be a breeze.

Depending on the size and type of your work piece, you can choose between two models, such as stationary and handheld models.

This tool accepts four different belt sizes, such as,

  • 3×18 inch

  • 3×24 inch
  • 4×24 inch

Here is the step by step instruction to help you work appropriately with a belt sander.

Secure your metal or wood work piece properly on your workbench or table.

Use the essential safety gears like gloves, goggles, and other items. Make sure to keep a sawdust collection bag in place to avoid flying sawdust that could be reason of dropping the tool and a subsequent injury. Some popular sanders include a dust collection hose.

Make sure that you keep the sander at a considerable distance and allow the motor to reach its full speed before bringing in contact with your work piece. It is safe to use a coarse belt and finish the operation with a fine grit.

Keep the sander’s rear part down to your wood. Be sure to hold the back handle firmly because you will have to use the handle for controlling the machine. Move the tool in a forward direction.

Make sure to bring the remaining part of your sander onto your wood as slowly and carefully as possible.

Hold the front handle and guide the sander across your work piece while moving the tool back and forth in even and smooth motions.

How to Change a Belt

Do not forget to disconnect your power cord while changing the belt. There is a release lever on either side of the sander. The lever releases the tension between your sander’s front and back drums. As you release the tension, slide the belt off of the drum. Bring a new belt onto the center of the belt and release the tension lever. Finally, plug your sander in. It’s all set.
