What is Domino Woodworking?

Domino woodworking is a technique of joining wood pieces together using a specialized tool called a domino joiner or a biscuit joiner. It involves creating mortises and inserting small wooden “dominoes” or “biscuits” into the mortises to create a strong and secure joint. This technique is widely used in furniture making, cabinetry, and other woodworking projects.

Definition

Domino woodworking refers to the process of joining wood pieces together using a domino joiner or biscuit joiner to create strong and durable joints. The domino joiner cuts a hole or mortise on the mating surfaces of the wood pieces, and then wooden dominoes, which are small, flat, and oval-shaped pieces, are inserted into the mortises. The dominoes are typically made of solid wood or compressed wood particles. When glued and clamped, the dominoes provide a strong bond between the wood pieces.

Origin

The concept of using small wooden biscuits or dominoes for joinery traces back to the late 1960s when Swiss company Festool introduced the first domino joiner. This innovative tool revolutionized traditional woodworking techniques by offering a faster, more accurate, and efficient way to create strong joints.

After cutting the wood pieces to size, it’s essential to smooth and sand the surfaces for a flawless finish. Use sandpaper, a sanding block, or a random orbital sander to remove any rough edges, splinters, or imperfections. Begin with a coarse grit sandpaper and gradually move to finer grits for a polished surface.

Joinery Preparation

Once the wood pieces are cut and sanded, it’s time to prepare them for the domino joinery. Determine the locations where the dominoes will be inserted and mark them on the wood pieces. Ensure that the marks align correctly on the mating surfaces to achieve accurate joinery.

The spacing between the dominoes depends on the joint’s requirements and the width of the wood pieces. Measure and mark the spacing accordingly, keeping in mind the overall design and strength considerations.

Joinery Techniques

Basic Domino Joints

The basic domino joint involves creating mortises on both wood pieces and inserting dominoes for a strong and straightforward connection. Here’s how to create a basic domino joint:

1. Set up your domino joiner according to the desired size of the dominoes.

2. Align the joiner with the marked locations and plunge it into the wood to create the mortises. Repeat this process on both wood pieces.

3. Apply wood glue to the mortises and insert the dominoes into one wood piece. Make sure the dominoes fit snugly into the mortises.

4. Assemble the wood pieces by aligning the mortises and inserting the dominoes, joining the pieces together.

5. Clamp the wood pieces together securely and wipe off any excess glue.

Advanced Domino Joints

Advanced domino joints require additional steps and considerations to achieve more complex and visually appealing connections. Here are a few examples:
