How to Cut Dovetails
To cut dovetails, start by using a notch to prevent the hand saw from cutting into the shoulder.
Then, cut out a notch from the shoulder at an angle using a chisel.
Use a chisel set into the marking gauge line to remove half-pin waste, with the bevel toward the waste.
For cutting out waste wood, the coping saw method is recommended.
Use a back saw with crosscut teeth to cut off the waste piece.
The size of the teeth on a dovetail saw does not significantly affect the process.
Clean up the tails with a narrower chisel, avoiding cutting up to the baseline.
About half of the waste should be removed using the chisel.
Create an undercut by using a slight angle, clearing waste in the joint.
Repeat the process on the other side of the board.
Use a chisel to clean out excess material from the joint and remove any excess wood beyond the pencil line.

Did You Know?
1. The first known dovetail joint dates back to ancient Egypt and was discovered in the tomb of a Pharaoh. This suggests that the technique has been used for thousands of years.
2. Dovetail joints were initially crafted by hand, but in the late 19th century, several inventors developed machines that could mass-produce dovetail joints, revolutionizing furniture manufacturing.
3. Some woodworkers prefer cutting their dovetails with a handsaw and chisel, while others opt for power tools like routers and jigs. The debate between hand-cut and machine-cut dovetails continues among woodworking enthusiasts.
4. Japanese carpenters have their own variation of dovetail joint called “mitsu-bari,” which translates to “three-way dovetail.” This unique joint features three tapered pins that fit into matching sockets, creating an incredibly strong bond.
5. In addition to woodworking, the dovetail joint is widely used in the construction of musical instruments. It is a popular choice for connecting the neck to the body of guitars, violins, and other stringed instruments due to its strength and durability.
Using A Notch For Precision
When it comes to cutting dovetails, precision is key. One technique that can help achieve this is using a notch to prevent the hand saw from cutting into the shoulder. By creating a small notch in the shoulder, you are ensuring that the saw does not go beyond the desired cutting line. This technique is particularly useful for maintaining clean and accurate cuts.
To create the notch, a chisel is used to cut out a small groove from the shoulder at an angle. This groove acts as a guide for the saw, ensuring that it stays on track and does not wander. By guiding the saw along the notch, you can achieve a more precise and controlled cut, leading to better fitting dovetail joints.
Angled Shoulder Notch Technique
To further enhance the accuracy of your dovetail cuts, the angled shoulder notch technique can be employed. Once the notch is created in the shoulder, a chisel is set into the marking gauge line with the bevel facing towards the waste wood.
This angled position of the chisel helps in removing half-pin waste more efficiently. By placing the chisel in this manner, it allows for a clean and precise removal of the waste material. The angle of the chisel creates an undercut, clearing out the waste from the joint and ensuring a tight fit between the dovetails.
This technique, when combined with the notch, provides an excellent way to achieve precise and well-fitting dovetails.
Efficient Removal Of Half-Pin Waste
In the dovetail cutting process, removing the half-pin waste is a crucial step. It is important to ensure that this waste is efficiently removed to achieve a clean and seamless joint.
The technique involves using a narrower chisel set into the marking gauge line, with the bevel facing towards the waste wood.
By using this narrower chisel, you can easily clean up the tails without cutting up to the baseline. It allows for a more controlled removal of the waste material, minimizing the risk of damaging the joint.
Approximately half of the waste is removed using the chisel, leaving behind a clean and precise joint that fits together seamlessly.
Coping Saw For Waste Wood Removal
One of the recommended methods for cutting out waste wood from dovetails is the use of a coping saw. This versatile tool is ideally suited for intricate and precise cuts, making it perfect for removing waste material between the dovetail pins or tails.
The coping saw features a thin blade with fine teeth, allowing for easy maneuverability and accurate cuts. By following the marking lines, you can use the coping saw to remove waste wood with precision, ensuring that the joint fits together seamlessly. This method is particularly useful when dealing with curved or irregular shaped dovetail joints.
Crosscutting With A Back Saw
To cut off the waste piece in a dovetail joint, it is recommended to use a back saw with crosscut teeth. This specific type of saw is designed for precise cross-cutting, which ultimately delivers clean and accurate results.
When using a back saw, it is crucial to position it correctly and meticulously follow the marked lines. This step guarantees a precise cut and ensures the joint fits together seamlessly.
By carefully guiding the back saw along the marked lines, you can cleanly and accurately remove the waste piece. This meticulous method not only creates a visually appealing dovetail joint but also ensures its durability and strength.
- Use a back saw with crosscut teeth for cutting the waste piece in a dovetail joint.
- Position the saw correctly and follow the marked lines for precise cuts.
- Carefully guide the back saw along the lines to cleanly remove the waste piece.
Dovetail Saw Teeth Size And Impact
Contrary to popular belief, the size of the teeth on a dovetail saw does not significantly affect the cutting process. While different tooth sizes may have a slight impact, it is not necessarily a determining factor in achieving precise dovetail joints. The most important aspects are proper technique, accuracy in following marked lines, and using the appropriate tools.
It is more important to focus on the quality and sharpness of the saw’s teeth rather than their size. A well-sharpened dovetail saw with properly set teeth will provide cleaner and more accurate cuts. Therefore, regardless of the size of the teeth, ensure that your saw is well-maintained and properly sharpened to achieve the best results.
In conclusion, mastering the art of cutting dovetails requires attention to detail and precision. By utilizing techniques such as:
- Using a notch to prevent saw drift
- Employing an angled shoulder notch
- Efficiently removing half-pin waste
- Using a coping saw for waste wood removal
- Crosscutting with a back saw
- Understanding the impact of dovetail saw teeth size
You can achieve beautifully crafted dovetail joints that will enhance the strength and aesthetics of your woodworking projects.
Frequently Asked Questions
What tool is commonly used to cut dovetails?
One commonly used tool for cutting dovetails is a dovetail saw. This saw typically has rip teeth, meaning that the cutting edges of the teeth are perpendicular to the length of the saw. Two excellent options for dovetail saws are the Japanese dozuki and the Western backsaw. Both of these saws are designed specifically for precision dovetail work and can make clean and accurate cuts.
What is the best angle for a dovetail?
The best angle for a dovetail joint depends on the type of wood and the desired joint strength. For hardwoods, a lower angle between 7° and 9° is typically recommended as it provides a good balance between joint strength and aesthetic appeal. This angle allows for a tighter fit between the wood fibers, creating a strong and durable bond. On the other hand, softwoods require higher angles between 10° and 14° to accommodate their more porous and less dense nature. These higher angles help compensate for the softer material by providing a deeper penetration of the dovetail, ensuring a solid connection. For half-blind dovetails, which are commonly used for decorative purposes, even higher angles ranging from 14° to 18° are suggested to achieve a visually appealing joint that conceals the end grain of the wood.
1. What are some alternative methods or tools that can be used to cut dovetails aside from traditional hand tools?
Some alternative methods or tools that can be used to cut dovetails include power tools such as a router or a dovetail jig. Using a router with a dovetail bit allows for precise and efficient cutting of dovetails. A dovetail jig is another option, which uses a router to guide the cutting process. These methods can save time and effort compared to hand tools, especially when working on larger projects or when needing to create multiple dovetails. However, it is important to note that using power tools or jigs may require a higher level of skill and experience to achieve the same level of precision and aesthetics as hand tools.
2. Are there any specific tips or techniques to follow when cutting dovetails on different types of wood or materials?
When cutting dovetails on different types of wood or materials, there are a few tips and techniques to keep in mind. Firstly, it’s important to choose the right type of dovetail joint for the specific wood or material being used. For example, softer woods like pine may require a narrower angle and smaller pins and tails, while harder woods like oak may allow for a wider angle and larger pins and tails.
Secondly, it’s crucial to pay attention to the grain direction of the wood. Cutting dovetails against the grain can result in splintering and a weaker joint. To avoid this, it’s best to align the layout of the dovetails with the grain direction, ensuring a sturdy and clean joint.
Additionally, using sharp tools is essential for cutting dovetails, regardless of the wood or material. Sharp chisels and dovetail saws will make the process much smoother and produce cleaner results. Finally, it’s always a good idea to practice on scrap pieces of the same wood or material before cutting dovetails on the actual project, as this allows for fine-tuning the technique and ensuring a precise fit.
