Dust is a radial arm saw's worst enemy. It dulls the blade, impedes optimal cutting, and poses health risks. But with a few clever tricks, you can maintain a clean workspace and prolong your saw's lifespan. Let's explore some radial arm saw tips and tricks to help you make the most of this versatile tool.
Before diving into advanced techniques, let's establish a solid foundation. Always ensure your radial arm saw is properly set up, maintaining the correct blade height and depth for your material. Regularly dust your blade with a wire brush to remove residue, and keep the guard clean and in working order.
Mastering Blade Changes
Ensuring your radial arm saw has the right blade for the job is crucial. Switching blades efficiently and safely is an art that can be mastered. Always remember to unplug your saw before changing blades to avoid any accidents.
To change the blade, first, release the tension on the arbor bolt. Next, prise the old blade off using a blade spreader or a simple screwdriver. Once the old blade is off, secure the new blade onto the arbor, making sure it's the correct side up. Tighten the arbor bolt and re-attach the saw guard.
Splitting Lumber Like a Pro
One of the radial arm saw's best features is its ability to split lumber. By lowering the blade and adjusting the fence, you can create perfectly symmetrical lumber pieces. Start by selecting the right blade for the job - a large-toothed, aggressive blade will tackle the task swiftly.
Secure your lumber on the fence, ensuring the cut line is aligned with the saw blade. Slowly lower the blade into the wood,starting with the tip and gradually applying more pressure. Keep the saw's handle parallel to the fence to ensure a straight cut, then slowly raise the saw as soon as you've reached the desired depth.
Easy Resawning and Bookmatching
Resawning and bookmatching are intricate techniques used to create stunning woodworking projects. Utilizing your radial arm saw, you can resaw lumber to create thin, uniform pieces, and bookmatch them for aesthetic appeal.
To resaw, use a thin kerf blade to minimize waste and reduce the effort required. Lower the blade and adjust the fence so the blade tip just grazes the lumber's edge. Slowly feed the wood through, applying even pressure. Once you've reached the desired thickness, flip the board over and repeat the process to create the bookmatched pair.
Expanding Cutting Capabilities
Your radial arm saw isn't limited to straight cuts. With a few jigs and accessories, you can transform your saw into a versatile cutting powerhouse capable of handling bevels, miters, and even curves.
Invest in a good miter gauge for accurate angle cuts. Ensure your saw's miter slot is clean and well-maintained to prevent binding. For bevel cuts, use a combination square to mark your desired angle, then adjust the bevel scale accordingly. Always test cuts on scrap wood before moving on to your final piece.
Creating Perfect Curves with a Jigsaw Attachment
With a jigsaw attachment, you can transform your radial arm saw into a powerful tool for cutting curves. Start by securing the jigsaw to your saw, ensuring a snug fit and proper alignment.
Use a scroll saw blade for fine curves, or a regular blade for broader arcs. Clamp your workpiece securely to your table or fence, then carefully lower the saw and guide it along your marked line. Keep the pressure even and maintain a steady speed to avoid burning the wood. Practice makes perfect with this technique, so don't be discouraged if your first attempts aren't flawless.
With practice and patience, you'll master these radial arm saw tricks and unlock its full potential. The smooth, controlled cuts and expanded cutting capabilities will elevate your woodworking projects to the next level. So strap in, keep your workspace clean, and happy sawing!
