How to Use a Belt Sander Machine
Using a belt sander, several steps must be done, namely:
- Preparation of safety materials: masks, glasses, gloves.
- Before you start sanding, you need to choose the right sanding belt for the job. Start with sandpaper that has a coarse grit, such as 40, 80, or 100; this will help remove most of the rough surface. Then use sandpaper with a finer grit, such as 180, to finish the project. To insert the belt into the sander, release the lever, usually found on the side of the sander, and slide it onto the wheel. Press lever closed to secure.
- Secure the sanded material to the work surface with clamps. This step prevents the board from slipping when sanding it.
- Turn on the sander and let it run for a few seconds to increase speed. Starting with the back of the sander, easily remove the belt sander machine against the wood. Make long, even strokes along the grain. Apply steady pressure to the sander, but avoid pressing too hard as this can damage the board. Check your work often.
- When done, remove the sander belt from the board. Check the sawdust bag. When full, remove the bag from the belt sander machine, empty it, and put it back in. Next, replace the sanding belt with a smoother one, and repeat the sanding process to finish your job.
