How to Use a Machine Sander

Working on projects yourself can save money and give you a sense of satisfaction. Even if you "do-it-yourself," you can achieve professional results using the right technique with the right tool. For example, a machine sander is great for smoothing surfaces when used properly.

Difficulty: Moderately Easy

Instructions

1. Use an orbital sander to take out marks left on wood after it's routed or just to take out imperfections. Its unique motion consists of the sandpaper disc spinning in circular motions while the pad moves in an oval loop. The benefit of this is that no single abrasive particle follows the same path twice. As a result, you end up with a swirl-free finish, even if you sand across the grain.

2. Change the sandpaper according to the job. Some jobs require a finer grit and others a coarser grit.

3. Keep the machine moving at a good slow pace at all times so it doesn't sand off too much wood in one single area.

4. Wear a mask to protect yourself from air-borne particles. This a precautionary measure, even though the machine has a dust collection system.

5. Start with a coarser grit of sandpaper when you're taking machine marks out of a surface. The starting point is normally 80 to 100 grit. To flush a surface and make it smooth, 100 grit is perfectly fine.
