The Versatile Sanding Block: An Essential Tool for Woodworkers

Types of Sanding Blocks
There are a few different types of sanding blocks that are commonly used by woodworkers. The most basic is the rectangular block, which is simply a piece of wood with surfaces on all sides for adhering sandpaper. Rectangular blocks are inexpensive and get the job done for basic sanding needs. However, they lack ergonomics and precision. Contoured sanding blocks have a curved shape that is designed to fit comfortably in the hand. They allow for more control during sanding. Sponge sanding blocks have an open-cell foam backing that helps sandpaper adhere smoothly without wrinkles. Foam backing is softer on materials being sanded. Specialty sanding blocks have unique shapes tailored for hard-to-reach areas or intricate details.

Choosing the Right Grit of Sandpaper

The grit of sandpaper used on a block determines the level of abrasiveness and fineness of the sanding marks. Coarser grits like 60-grit or 80-grit are used for stock removal when smoothing rough surfaces or shaping wood. Medium grits from 100-grit to 150-grit are for final shaping and smoothing. Finer grits of 180 through 240 are commonly used as a final sanding step before finishing to produce a very smooth surface. Ultra-fine grits of 320 and above are best reserved for “wet sanding” when combined with water or mineral spirits during final finish preparation.

Building Custom Sanding Blocks

While pre-made blocks work well, woodworkers can also build custom blocks specific to their needs. Any wood such as poplar or MDF can be used as a base. Cutting blocks to fit curved surfaces requires bandsawing or template routing. Adding non-slip features is also useful. Some options include rubber backing, Velcro strips, or adhesive-backed sandpaper made for blocks. Wood burners or carving tools allow adding identifying marks. Graphite or wax lubricates sandpaper for smoother results. Blocks should be flat, sturdy, and about 1⁄4” thick for control during sanding applications.

General Sanding Techniques

Using a sanding block requires applying even pressure with modest force. It’s best to sand with the grain in long, sweeping motions. Change directions periodically for a uniformly sanded surface. Keep the block flat on the material. Inspect for defects after each grit change. Sandpaper wears out quickly, so monitor for clogging or glazing over. Blow or wipe away dust regularly during use. Work in sections when sanding large areas to avoid swirls or unevenness. Change sandpaper frequently or when it ceases to scratch or takes on a shiny appearance. Proper sanding sets the stage for a flawless finish.

Applications for Specific Projects

Sanding blocks are indispensable for flattening warped sheets. Slide a flexibly-backed block across surfaces using light pressure to remove high spots. Fine grit paper smooths the entire plane. When shaping components on a router table, a block sands curved edges evenly without rounding off details. Block sanding inside corners prevents trapped swirls or heavy scratches. Use a dowel-shaped block to smooth long grooves, dados and other recessed hinge mortises. Fine-tuning glue joints is simple with a block and a tight corner can be neatened. Sanding power tool surfaces like tables/fences leaves a more even scratch pattern than by hand. Blocks finish cabinetry casegoods like carcasses and face frames smoothly without defects.

Final Considerations

Like any shop tool, sanding blocks deserve proper care and maintenance. Periodically inspect blocks for wear and replace if cracked or warped. Vacuum or blow out dust buildup beneath or inside open-cell foam backings. Keep a variety of blocks handy, labeled and organized. This makes it easy to grab the right one for each project phase. Stock several grits of sandpaper conveniently packaged on a roll or sheet. With the right blocks and techniques, sanding need not be viewed as a dreaded task, but rather an enjoyable part of achieving a high quality, professional surface finish. No workshop should be without these versatile and affordable sanding essentials.

In conclusion, sanding blocks are an indispensable tool for woodworkers of all skill levels. From basic rectangular blocks to contoured specialty shapes, they deliver consistent and uniform scratch patterns on curves and flat surfaces alike. With the ability to easily customize blocks for specific applications, woodworkers can sharpen their sanding techniques for flawless results. Keeping blocks properly maintained along with an organized selection of grits ensures hassle-free sanding on projects of any scale. The versatility and affordability of sanding blocks makes them a staple workshop must-have.
