To make strong and good-looking woodworking joints, you can learn how to cut dovetails on a table saw. This involves marking out the dovetails, making cuts for the tails and pins, and perfecting the joint for a precise fit.
Dovetail joints provide a sturdy connection between two pieces of wood. This is important because it prevents twisting and pulling forces. They also enhance the visual appeal of the finished piece.
In this guide, we’ll take you through the process of learning to cut dovetails on a table saw. But if you want to learn more about dovetails in general, you can check out the manual on table saw dovetails before jumping ahead!
Or, since you’re concerned about precise details, learn more about how to align the table saw blade so you can have the perfect cuts.
Step 1: Preparing to cut dovetails on a table saw
To start cutting dovetails on a table saw, you need to get ready with the right equipment and workspace. Select a thin-kerf, flat-top grind blade suitable for the job. Adjust the blade height and fence of the table saw to match the angles of your chosen dovetail joint.
It’s crucial to follow safety precautions to prevent movement during cuts, such as:
- Wearing eye and ear protection
- Using push sticks or blocks to keep your fingers safe
- Securing the workpiece to the sled or table
Proper preparation ensures accurate cuts and a safe workpiece.
Step 2: Marking out the dovetail joints
Before making any cuts on the table saw, it’s essential to mark out the dovetail joints accurately. This involves measuring and marking out the tails and pins on both workpieces and transferring the marks to the actual workpiece.
Start by measuring and marking the tails on one workpiece using a dovetail marking gauge. This tool has a pin and a wedge that can be adjusted to match the angle of your dovetail joint. Score a line across the grain of the wood with the pin, flip the gauge, and use the wedge to mark out the angled cut for the tail.
After marking out the tails on one workpiece, it’s time to mark out the corresponding pins on the other piece. Make sure to match the angles and spacing of the tails. Use a marking knife or pencil to transfer the marks accurately onto the workpiece.
Step 3: Cutting the tails
Once you’ve marked out the tails on your workpiece and set up the table saw, it’s time to make the cuts for the tails.
Start by securing the workpiece to the table saw sled using clamps or other means to keep it stable and secure. Then, make the cuts for the tails by slowly pushing the sled and workpiece through the blade, ensuring you keep your fingers clear. After making the cuts, remove the waste material by chiseling or sawing it away.
Check the accuracy of your cuts by fitting the tails into the corresponding pins on the other workpiece. If the fit is too tight or loose, you may need to adjust the blade height or fence position before moving on to the pin cuts.

Step 4: Cutting the pins
To cut the pins, adjust the table saw to the right angle and height, and make the cuts as you did for the tails. Remove the waste material as before.
Check the fit by putting the pins into the corresponding tails on the other piece. If it’s too loose or tight, adjust the blade height or fence position, and fine-tune the joint.
Step 5: Fine-tuning the joints
With the tails and pins cut, it’s time to fit them together and fine-tune the joint. This involves adjusting the cuts as needed to get a perfect fit and then sanding and finishing the joint to achieve the desired look and feel.
Fit the tails and pins together and check for any gaps or misalignments. Use a chisel or saw to adjust the cuts as needed until the joint fits tightly and securely. Then, sand and finish the joint to match the rest of your project. With these steps complete, you should have a beautiful and sturdy dovetail joint created using your table saw.
