Rounding edges with a router not only enhances the aesthetic appeal of your woodworking projects but also adds durability by removing sharp edges that can cause damage or splinters. This detailed guide will walk you through every step of the process, from preparing your tools and materials to executing the routing and finishing touches.
Understanding the Router and Its Components
Router and Bit Selection
Choosing the Right Router: Routers come in various configurations, including plunge routers, fixed-base routers, and combination routers. For edge rounding, a fixed-base router is often preferred for its stability. Ensure your router is compatible with the bit size you plan to use.
Selecting the Edge-Rounding Bit: Edge-rounding bits are available in various radii, ranging from small curves for fine details to larger curves for more pronounced edges. The radius of the bit will dictate the size of the rounded edge. Choose a bit that matches the desired curve for your project.
Router Setup
Installing the Bit: Insert the edge-rounding bit into the router’s collet. Make sure the bit is inserted fully and tightened securely to prevent movement during routing. Check the bit’s depth setting, as this controls how much material will be removed. Adjust it according to the desired roundness of the edge.
Adjusting Speed Settings: Set the router’s speed based on the type of wood and the size of the bit. Generally, higher speeds are better for smoother cuts, especially with smaller bits. Refer to the router’s manual for recommendations on speed settings for different bit sizes and wood types.
Preparing the Wood for Routing
Wood Selection and Preparation
Choosing the Wood: Select wood that is free from defects like knots, cracks, or warping. Defects can cause irregularities in the routing process and affect the final appearance. Hardwoods and softwoods both work well, but ensure the wood is properly dried to prevent future movement or splitting.
Marking the Edges: Use a pencil to clearly mark the edges you plan to round. This visual guide helps keep your routing aligned with your intended design. For more precision, use a straightedge or measuring tape to ensure accurate markings.
Securing the Wood
Clamping the Wood: Secure the wood piece to your workbench or router table using clamps. Ensure the wood is stable and does not shift during routing. Proper clamping prevents movement, which can lead to uneven cuts or inaccuracies.

Routing the Edges
Starting the Router
Powering Up: Turn on the router and allow it to reach full speed before making contact with the wood. This helps achieve a smoother cut and reduces the risk of burning the wood. Hold the router firmly to control its movement.
Executing the Cut
Guiding the Router: Slowly and steadily move the router along the marked edge. Maintain a consistent speed and pressure to ensure an even cut. Keep the router base flat against the wood surface to achieve a uniform roundness. For best results, use the router’s fence or guide if available to help maintain a consistent edge.
Making Multiple Passes: To avoid overloading the router and to achieve a finer finish, make several shallow passes rather than one deep cut. Each pass should remove only a small amount of material, which helps in controlling the routing process and reduces the likelihood of splintering or burning the wood.
Checking the Results
Inspecting the Edges: After completing the routing, carefully inspect the rounded edges for consistency. Ensure the entire edge is evenly rounded and smooth. Look for any irregularities or imperfections and address them as needed.
Touching Up: If necessary, use a sanding block or fine-grit sandpaper to smooth out any minor imperfections or rough spots left by the router. Sand in the direction of the grain to maintain a smooth finish.
Finishing Touches
Sanding
Final Sanding: Use fine-grit sandpaper (such as 180 to 220 grit) to perform final sanding on the rounded edges. Sand by hand or with an orbital sander to achieve a smooth and polished surface. This step removes any residual router marks and ensures a professional finish.
Inspecting the Finish: After sanding, check the edges to ensure they are free from tool marks or roughness. A well-sanded edge will enhance the overall appearance of your project and provide a smooth feel.
Applying Finish
Staining or Painting: Apply stain or paint to enhance the wood’s appearance and achieve the desired color. Follow the manufacturer’s instructions for application and drying times. Ensure even application to prevent streaks or blotches.
Clear Coating: For added protection and durability, apply a clear polyurethane or lacquer finish. This protective layer seals the wood, provides a glossy surface, and helps resist wear and tear. Apply the finish according to the product instructions and allow adequate drying time.

Safety and Maintenance
Safety Precautions
Wear Safety Gear: Always wear safety glasses and hearing protection when operating a router. The router produces noise and debris that can pose a risk to your eyes and ears.
Secure the Workpiece: Ensure the wood piece is securely clamped and stable before starting the router. Avoid loose clothing or jewelry that could get caught in the router.
Router Maintenance: Regularly clean and inspect the router and bit for wear and tear. Remove any wood residue from the bit and check for damage. Proper maintenance ensures optimal performance and safety.
Maintenance Tips
Clean the Bit: After use, clean the router bit to remove any wood residue. This helps maintain the bit’s sharpness and efficiency. Use a brush or compressed air to remove debris.
Inspect the Router: Regularly check the router for any signs of damage or malfunction. Ensure all components, including the collet and base, are in good working condition. Proper maintenance prolongs the tool’s lifespan and ensures reliable performance.
Conclusion
Rounding the edges of wood with a router is a technique that combines precision, skill, and attention to detail. By following this detailed guide, you can achieve beautifully rounded edges that enhance the appearance and durability of your woodworking projects. From selecting the right tools and setting up your router to executing the cut and applying finishing touches, each step is crucial for achieving professional results. With practice and careful execution, you’ll be able to master this essential woodworking skill and elevate the quality of your projects.
