How to Use a Biscuit Joiner
To use a biscuit joiner, begin by preparing the two pieces of wood that you want to join together.
Make sure they are flat, smooth, and properly sized.
Then, set the depth and width of the biscuit joiner according to the size of the biscuit you will be using.
Align the joiner with the edge of the first piece of wood and make a crescent-shaped cut using the joiner’s blade.
Repeat this step on the other piece of wood.
Apply glue to the biscuit and insert it into the slot on one piece of wood.
Align the two pieces of wood and clamp them together.
Let the glue dry completely.
Trim any excess biscuit and sand the joint until it is smooth and seamless.

Did You Know?
1. Biscuit joiners were first invented in the 1950s by an Australian cabinet maker named Alan McPherson. He originally called his invention the “plate joiner” before it became widely known as the biscuit joiner.
2. The biscuits used in biscuit joinery are typically made of compressed beech wood and come in three standard sizes: #0, #10, and #20. The biscuit’s size depends on the thickness of the material you are joining.
3. While biscuit joiners are most commonly used in woodworking to join two pieces of board together, they can also be used for alignment purposes. For example, they can be used to align panels during glue-ups or to ensure precise alignment when making cabinets.
4. The term “biscuit” in biscuit joinery does not refer to the treat we often enjoy with a cup of tea. Instead, it comes from the biscuit’s shape, which resembles a baby biscuit or cracker.
5. Although biscuit joiners are traditionally electrically powered, there are also manual or hand-operated versions available. These are handy when working in remote locations or when precision is required in small-scale projects.
Introduction To Biscuit Joiners
Woodworking is a sophisticated and intricate craft that requires precision and skill. Joining two pieces of wood seamlessly is key in carpentry. While nails, screws, and staples have been traditionally used, there is a more refined approach available – the biscuit joiner.
- The biscuit joiner, also known as a plate joiner, is an electric woodworking tool.
- It enables woodworkers to create strong, smooth, and virtually invisible joints.
In this guide, we will explore various techniques and methods for using a biscuit joiner. Its purpose is to help carpenters achieve professional and seamless joints.
The Cutting Process And Crescent-Shaped Holes
The central function of a biscuit joiner is to create slots in opposite edges of two pieces of wood to accommodate the wooden biscuits. The cutting process begins with the biscuit joiner’s small blade, which typically measures 4 inches or 101.6 millimeters in diameter. This blade is carefully aligned and set to the desired depth.
With the biscuit joiner turned on, the blade is guided along the edge of the first piece of wood to cut a crescent-shaped hole. The same process is repeated on the corresponding edge of the second piece of wood. The precision and accuracy of the cuts are essential to ensure a snug fit for the biscuits and ultimately create a strong joint.

- The small blade measures 4 inches or 101.6 millimeters in diameter
- The blade is aligned and set to the desired depth
- The blade is guided along the edge of the wood to cut a crescent-shaped hole in both pieces
- Precision and accuracy are crucial for a snug fit and strong joint.
Using Wooden Biscuits And Clamping For Seamless Joints
Once the crescent-shaped holes are cut, it is time to introduce the wooden biscuits. These oval-shaped wooden pieces, usually made from compressed wood, are coated with glue and placed in the slots on each piece of wood.
The boards are then clamped together tightly, allowing the glue to bond the biscuits to the wood.
The clamping process is crucial to achieve a seamless joint. It ensures that the two pieces of wood are held firmly together, allowing the glue to dry and create a strong bond. The clamps need to be applied evenly along the joint, exerting sufficient pressure to bring the boards together without causing damage.
- The crescent-shaped holes are cut first.
- Wooden biscuits, oval-shaped wooden pieces made from compressed wood, are used.
- The boards are clamped tightly to create a strong bond.
- Even application of clamps along the joint is important.
- Sufficient pressure should be exerted to bring the boards together without causing damage.
Measurement And Limitations Of Biscuit Joints
When it comes to biscuit joints, considering the measurements and limitations is essential. The size of the biscuit used plays a significant role in the overall strength of the joint. For example, a #0 biscuit measures about 21/8″ wide. It is crucial to note that biscuit joints cannot be hidden in stock narrower than this measurement.
One common limitation of biscuit joints is their inability to be used in narrower face frames. Face frames are typically narrower than 21/8″, so alternative methods or specialized biscuits are required to achieve a strong joint. However, for joints that won’t be visible, a useful technique is reinforcing the joint with full-size biscuits on the backside.
- Consider the measurements and limitations associated with biscuit joints.
- Biscuit size affects joint strength.
- Narrow face frames require alternative methods or specialized biscuits.
- Reinforce non-visible joints with full-size biscuits on the backside.
Reinforcing Joints With Full-Size Biscuits On The Backside
If you frequently work with narrow face frames and need reinforcement, the biscuit joiner can be a useful tool. It has an extra blade designed for cutting smaller face-frame slots, allowing you to create slots for special 1 1/4″-long biscuits. Using this technique will provide additional strength and stability to the joint, ensuring a secure connection.
Note: This method may not be necessary for typical biscuit joint applications. It is more suited for situations where a narrower face frame requires extra reinforcement.
Gluing, Clamping, And Finishing The Joint
Once the biscuits are set in place, it is time to proceed with gluing, clamping, and finishing the joint. The mating boards should be coated with glue, ensuring that both the biscuits and the edges of the wood are adequately covered. The clamps are then applied, exerting even pressure across the joint to bring the boards together.
After allowing sufficient time for the glue to dry, the excess biscuits can be cut off using a saw or a chisel. It is crucial to ensure that the biscuits are cut flush with the surface of the wood to achieve a seamless joint. A final step involves sanding the joint to create a smooth finish, blending the joint seamlessly with the rest of the wood.
The biscuit joiner is an invaluable tool for woodworkers seeking to achieve strong, smooth, and seamless joints. By following the techniques and methods discussed in this guide, you can use a biscuit joiner with confidence and elevate your woodworking projects to the next level.
Frequently Asked Questions
Is it worth buying a biscuit joiner?
While a biscuit joiner may not add extra strength to a joint, it can still be a worthwhile purchase for its convenience. With accurately planed edges, a simple butt joint can suffice in terms of strength.

With these 12 helpful tips, the biscuit jointer can be utilized to its full potential, allowing it to enhance productivity and produce more robust woodworking projects.
What are the 4 steps of the biscuit method?
To execute the biscuit method, start by measuring the dry ingredients into a bowl. Then, incorporate the shortening, margarine, or butter into the mixture until it becomes granular. In a separate bowl, combine the liquid ingredients. Finally, combine the liquids with the dry ingredients and mix until well incorporated. These four simple steps will ensure a delightful batch of biscuits.
