What is an orbital sander and how does it work?

An orbital sander is a power tool designed for sanding surfaces to achieve a smooth finish. It utilizes a circular sanding disc that moves in an elliptical orbit, ensuring that the sanding motion is random and minimizes the risk of swirl marks on the surface. This makes it ideal for both finishing work and light stock removal on materials like wood, plastic, and metal.

The orbital sander operates at various speeds, allowing you to adjust the level of aggressiveness based on the material you are working with and the desired finish. By using different grits of sandpaper, you can remove old finishes, smooth rough surfaces, and prepare the surface for painting or staining.

How do I choose the right sandpaper grit for my project?

Choosing the right sandpaper grit is crucial for achieving the desired finish and for the effectiveness of your sanding project. Generally, the grit scale runs from coarse to fine. Coarse grits (like 40-60) are best for heavy material removal and leveling surfaces, while medium grits (like 80-120) are suitable for smoothing rough areas and preparing surfaces for finishing. Fine grits (180-220 and above) are used for final finishing and polishing.

When selecting your sandpaper, consider the state of the surface you’re sanding. If you’re starting with a rough surface or an old finish, begin with a coarser grit to remove material quickly. As you progress, switch to finer grits to refine the surface until you achieve the smoothness you desire. Always remember to sand in the direction of the grain when working with wood to avoid scratches.
