Woodworking is a craft that demands precision, attention to detail, and the right tools. Whether you are a professional woodworker or a passionate hobbyist, achieving consistent thickness in your projects is crucial for a polished and professional outcome. This is where a double-sided planer comes into play. In this article, we will delve into the world of crafting symmetry and explore the benefits and techniques of using a double-sided planer to achieve flawless consistency in woodworking projects.

The Double-Sided Planer: An Overview

The double-sided planer, also known as a dual surfacer or twin planer, is a powerful and versatile tool used in woodworking workshops to ensure even thickness on both sides of a board. Unlike traditional planers that only surface one side at a time, the double-sided planer offers a unique advantage by allowing simultaneous surfacing of both sides of a board in a single pass.

Using advanced technology, this machine consists of two planing heads positioned opposite to each other, with the board passing between them. With each pass, the machine removes a precise amount of material from both sides, resulting in an evenly thicknessed board. This saves time, increases efficiency, and eliminates the need to flip the board for a second pass, as required by single-sided planers.

The Advantages of Consistent Thickness

Consistency is the key to achieving high-quality woodworking projects. Let's explore the advantages of utilizing a double-sided planer to achieve consistent thickness:

1. Enhanced Aesthetics: One of the primary benefits of consistent thickness is the visual appeal it adds to your projects. When all your boards are of the same thickness, it creates a harmonious and professional look. Uniform thickness ensures clean lines, seamless joinery, and a polished finish, resulting in aesthetically pleasing woodworking pieces.

2. Improved Functionality: Consistent thickness not only enhances the appearance but also improves the functionality of your woodworking projects. Whether you are crafting furniture, cabinetry, or flooring, having uniformly thick boards ensures stability, even weight distribution, and ease of assembly. This translates into longer-lasting and more durable finished products.

3. Easier Joinery: Joining boards together is a fundamental aspect of woodworking. When working with inconsistent thickness, achieving tight and seamless joints becomes a challenge. By using a double-sided planer to ensure consistent thickness, you eliminate the guesswork and frustration associated with uneven boards. This makes joinery tasks such as edge gluing, dovetailing, or tongue and groove assembly much easier and more precise.

4. Efficient Material Utilization: Inconsistent thickness can lead to wastage of expensive wood. When boards are uneven, excess material needs to be removed to achieve uniformity, resulting in unnecessary material loss. By utilizing a double-sided planer, you can optimize material utilization, reducing waste, and increasing cost-effectiveness.

5. Time-Saving: Time is a valuable resource, particularly for professional woodworkers. Traditional planers require additional passes and manual flipping of boards, adding time and effort to the process. Double-sided planers, on the other hand, significantly reduce the time required to surface boards, allowing craftsmen to increase their productivity and tackle more projects within the same timeframe.

Techniques for Achieving Consistent Thickness

While utilizing a double-sided planer simplifies the process of achieving consistent thickness, it is essential to follow proper techniques for optimal results. Below, we discuss some key techniques to employ:

1. Initial Board Preparation: Begin by selecting boards that are close to the desired thickness. While the double-sided planer can remove material from both sides, starting with boards of similar thickness minimizes the amount of material needing removal. This speeds up the planing process and ensures a more consistent end result.

2. Adjusting the Planer: Proper adjustment of the double-sided planer is crucial to achieving consistent thickness. Begin by ensuring that the infeed and outfeed tables are parallel and properly aligned. This prevents snipe and guarantees that the board maintains even pressure throughout the planing process. Additionally, adjusting the cutting depth precisely ensures an accurate removal of material.

3. Feed Rate: Controlling the feed rate of the board is essential for consistent thickness. Feeding the board too quickly can result in a rough and uneven finish, while feeding it too slowly can cause burn marks. Experiment with different feed rates to find the optimal speed that ensures smooth and consistent results.

4. Blade Maintenance: Regular maintenance of the planer's blades is vital for achieving consistent thickness. Dull blades can lead to tear-outs and an uneven finish. Ensure the blades are sharp and properly aligned for precise material removal. Regularly clean the blades from debris and always handle them with care to avoid any damage.

5. Final Sanding: Although a double-sided planer provides an excellent surface finish, it may require minor sanding for absolute perfection. Once you have achieved consistent thickness, lightly sand the boards with fine-grit sandpaper to remove any imperfections and achieve a smooth, polished surface.


Consistency is the foundation of exceptional woodworking projects, and achieving consistent thickness is paramount. By utilizing a double-sided planer, woodworkers can ensure uniformity, enhance aesthetics, improve functionality, ease joinery tasks, optimize material utilization, and save time. Remember to follow the proper techniques, from initial board preparation to final sanding, to maximize the benefits of this powerful tool. So, unlock the potential of crafting symmetry with a double-sided planer and elevate your woodworking to new heights of excellence.
