🛠️ Making Curved Moldings: Taking Your Woodworking Projects to Another Level
Woodworking projects often involve intricate details, adding a touch of elegance and sophistication. One such element that can elevate your projects to another level is curved moldings. These gracefully-curved adornments can be found on clocks, cabinets, and various furniture pieces, leaving woodworkers wondering how they are made. In this article, we will demystify the process of creating these curved moldings and show you that it can be a rewarding skill to master.
Introduction
Woodworking enthusiasts often shy away from projects that require curved moldings due to the perception that they are difficult to create. However, we will demonstrate that with the right techniques and tools, you can confidently embark on these projects and achieve stunning results.
Understanding Curved Moldings
Curved moldings are not simply cut straight and bent into shape. The desired profile is meticulously routed into the curved edge of wider workpieces, which are then trimmed to create the final molding. While the process may seem complex, we will guide you through each step, making it accessible even to beginner woodworkers.
Making a Template
Before diving into the intricacies of crafting curved moldings, it is essential to have a template. If you have not already created one that matches your project's curve, you will need to make one. This involves attaching your top or bottom panel to a piece of quarter-inch MDF using double-sided tape. By employing a flush trim bit, you can trace the desired curve onto the template, creating a master template that will serve as your guide.
Attaching the Template to the Molding Stock
To begin crafting the curved molding, secure the master template to the top of your molding stock using double-sided tape. It is crucial to use wood that is as wide as the entire curve of the molding, ensuring ample material for shaping. Using a bandsaw, rough cut the shape along the edge of the template, maintaining precision while getting as close to the template's edge as possible without cutting into it.
Using a Flush Trim Bit to Finish the Curve
Once the initial curves are established, remove the template and employ a flush trim bit on your router to refine the shape further. This specialized bit will accurately trim away any excess material, leaving you with a clean edge that matches the curve of your template. Safely using bearing guided router bits on a router table without a fence requires some considerations, such as making the template slightly longer than the workpiece on each end to facilitate the beginning and ending of the cut.
Using a Profiled Router Bit to Cut the Desired Shape
With the curves refined, it is time to truly bring your curved molding to life. Install a profiled router bit that matches the desired shape you want to create into the curved edge. As you guide the router along the wood, the bit will carve out the intricate profile, achieving the elegance and sophistication synonymous with curved moldings. Be sure to maintain control and precision throughout the process, paying particular attention to the beginning of the cut.
Safety Tips for Using Bearing Guided Router Bits
When using bearing guided router bits on a router table without a fence, it is crucial to prioritize safety. One effective approach is to install a starting pin in the top of the router plate, allowing you to leverage the workpiece onto the bit smoothly. This provides you with better control, especially at the beginning of the cut. Additionally, extending the master template slightly beyond the workpiece on both ends enables a safer, catch-free routing experience.
Creating Layered Curved Moldings
To introduce complexity and create truly unique profiles, you can experiment with layered curved moldings. By combining multiple layers, each shaped with simple router bits, you can achieve elaborate designs that would otherwise require more specialized tools. We invite you to delve deeper into this technique by referring to our comprehensive video guide featured in the January 2017 issue of Stumpy Nubs Woodworking Journal.
Trimming the Profiles from the Wider Boards
When working with layered curved moldings, it is necessary to trim the profiles away from the wider boards they were cut on. This process requires attention to detail, as the bottom layer must be trimmed off wider than the top layer. One effective method involves stacking the workpieces as desired and marking the trimming lines before carefully proceeding to the bandsaw. Accuracy is paramount, as the curvature of the back must flawlessly match your cabinet or project for a seamless integration.
Creating a Negative Template for the Bottom Layer
To ensure a precise fit between the curved molding and your project, a negative template must be created for the bottom layer. This template serves as a reverse counterpart to your master template and allows for accurate trimming. For a detailed explanation of the process, we recommend watching our video guide featured in the October 2017 issue of Stumpy Nubs Woodworking Journal.
Trimming the Moldings with the Negative Template
Once the negative template is prepared, you can proceed to trim the moldings from the larger workpieces. Secure the negative template to the underside of your stock using double-sided tape, taking advantage of the greater surface area to ensure a firm attachment. Carefully trim away the excess material on the bandsaw, leaving a small margin from the template. Move on to the router table, where the flush trim router bit will help you achieve the desired final shape. Take additional passes if needed for a clean, precise cut.
Gluing the Layers Together
For layered curved moldings, the final step involves securely gluing the layers together. Use glue sparingly to prevent excessive squeeze-out, which can be challenging to clean up and may affect the overall finish. Similarly, avoiding any gaps will contribute to a seamless appearance. Achieving a well-aligned and bonded connection enhances the structural integrity and aesthetic appeal of your curved complex molding.
Applying the Techniques to Large-Scale Moldings
While this article has primarily focused on small-scale curved moldings, rest assured that these techniques can be applied to larger projects as well. Scaling up the process requires careful planning and additional considerations. To explore this topic in-depth, we encourage you to read the latest issue of Stumpy Nubs Woodworking Journal, where we delve into various aspects of creating large-scale curved moldings.
Conclusion
Curved moldings add a touch of sophistication and elegance to woodworking projects, showcasing your craftsmanship and attention to detail. By following the step-by-step techniques discussed in this article, you can confidently embark on projects that previously seemed daunting. Let your creativity flow and explore the limitless possibilities of curved moldings, elevating your woodworking projects to new heights.
