Hand held belt sanders are versatile power tools used primarily in woodworking and furniture refinishing. They excel at quickly removing material from large surfaces, smoothing rough wood, and leveling uneven areas. These sanders are also useful for stripping old finishes, shaping wood, and even some metal finishing tasks. Their portability and power make them indispensable for both DIY enthusiasts and professional woodworkers.
What Are the Primary Uses of Hand Held Belt Sanders in Woodworking?
Hand held belt sanders are workhorses in the woodworking shop, offering a range of applications:
- Rapid Material Removal: Quickly strip away old finishes or remove large amounts of wood.
- Surface Smoothing: Flatten rough boards or smooth out imperfections.
- Edge Shaping: Bevel or round edges on boards and panels.
- Leveling: Even out uneven surfaces or joints.
Techniques for Effective Woodworking with Belt Sanders
- Always sand with the grain to avoid damaging the wood.
- Use multiple passes, overlapping each by about half the sander width.
- Apply gentle pressure; let the sander’s weight do the work.
- Start with coarse grits (40-80) for heavy removal, then progress to finer grits (120-220) for smoothing.
How Can Hand Held Belt Sanders Be Used for Metal Finishing?
While primarily designed for wood, belt sanders can tackle some metal finishing tasks:
- Removing Rust: Strip away surface rust from metal objects.
- Smoothing Welds: Level and smooth welded joints.
- Polishing: With the right belts, achieve a polished finish on metal surfaces.
Safety Precautions for Metal Sanding
- Use belts specifically designed for metal.
- Be aware of spark generation and ensure a clean, fire-safe work area.
- Wear appropriate personal protective equipment (PPE).
