How To Cut A Blind Dado On A Table Saw
When it comes to woodworking, creating strong and sturdy joints is essential for a successful project. One joint that is commonly used is the blind dado, which is a groove cut into one piece of wood that will house another piece of wood. This creates a secure and hidden joint that adds both strength and aesthetics to your project. If you’re wondering how to cut a blind dado on a table saw, you’re in the right place.
Before you begin, it’s important to note that cutting a blind dado can be a bit more challenging than a through dado, as the groove will not go all the way through the workpiece. However, with the right tools and techniques, you can achieve precise and accurate results.
The first step is to set up your table saw. Start by installing a dado blade stack that matches the width and depth of the dado you want to cut. Make sure to position the blade at the correct height, which is typically around 1/3 the thickness of the workpiece. Once the blade is set up, adjust the fence so that it aligns with the desired width of the dado.
Now that you have the table saw set up, it’s time to make the cuts. Start by making a series of straight cuts along the length of the dado, using the fence as a guide. Make sure to move the workpiece slowly and steadily to ensure clean and accurate cuts. Once the straight cuts are complete, use a chisel to remove the waste material and clean up the bottom of the dado. Take your time and be careful to not remove too much material, as this can affect the fit of the joint.
With the dado cut and the waste material removed, you can now test the fit of your joint. Insert the piece of wood that will fit into the dado and check for any gaps or areas that may need adjustment. If necessary, use a chisel or sandpaper to fine-tune the fit until the joint is tight and flush. Once you’re satisfied with the fit, you can proceed with assembling your project, knowing that your blind dado joint will provide both strength and visual appeal.
In conclusion, cutting a blind dado on a table saw requires careful setup and precision cuts. By following these steps and taking your time, you can achieve a strong and clean joint that will enhance the quality and durability of your woodworking projects.

What is a blind dado?
A blind dado is a woodworking joint that is used to join two pieces of wood together, creating a strong and durable connection. It is called a blind dado because it is not visible from the outside of the finished piece, as it is hidden within the wood.
A blind dado is created by cutting a groove or channel into one piece of wood, known as the dado, and then fitting another piece of wood, known as the tenon, into the groove. This creates a flush and seamless joint that is both strong and aesthetically pleasing.
Blind dados are commonly used in cabinet making and furniture construction, where a strong and hidden joint is required for stability and durability. They are often used to join shelves to the sides of cabinets, or to connect legs to tabletops.
The process of cutting a blind dado requires careful measurements and precise cuts. It can be done using various tools, such as a table saw, router, or dado blade, depending on the specific project and desired outcome.
Overall, blind dados are a versatile and reliable woodworking joint that allows for strong and hidden connections between pieces of wood.
Step-by-step guide on how to cut a blind dado on a table saw
Cutting a blind dado on a table saw can be a useful technique to create strong and precise joinery in woodworking projects. The following step-by-step guide will help you understand the process:
Step 1: Set up the table saw
Start by adjusting the table saw blade height to the desired depth of the blind dado. Make sure to wear appropriate protective gear, such as safety glasses and gloves, before proceeding.
Step 2: Mark the dado location
Measure and mark the location of the blind dado on your workpiece. Use a pencil or marking knife to make accurate and visible marks. Ensure that the dado is positioned according to your project plans.
Step 3: Set up the table saw fence
Align the table saw fence parallel to the blade. The distance between the fence and the blade should match the desired width of the blind dado. Use a measuring tool or a dado sled to ensure accurate and consistent results.
Step 4: Make a series of cuts
Place the workpiece against the fence, with the marked dado location facing the blade. Use a push stick or push block to safely feed the workpiece into the blade. Make multiple passes, incrementally moving the workpiece to create the blind dado.
