The herringbone glue up, a technique popularized by woodworkers like Christopher Schwarz, is a method of joining boards to create a herringbone pattern without using biscuit joiners or other specialized tools. This technique is not only visually appealing but also strengthens the joint, making it an excellent choice for furniture making and other woodworking projects.
Understanding the Herringbone Glue Up
The herringbone glue up involves creating a series of interlocking fingers on the edges of the boards that will be joined. These fingers are cut at a 45-degree angle, allowing the boards to fit together like pieces of a puzzle. The resulting joint resembles the bones of a herring, hence the name.
One of the key advantages of this technique is that it allows for the use of narrower boards, which can be more stable and less prone to warping than wider boards. This makes it an ideal method for creating wide panels or tabletops.
Tools and Materials Needed
- Hand saw or miter saw
- Chisel
- Pencil
- Ruler or measuring tape
- Clamps
- Wood glue
- Safety glasses
- Ear protection (if using power tools)
Optional Tools
- Marking gauge
- Coping saw
- Router (for cutting the fingers)
Steps to Create a Herringbone Glue Up
1. Mark the Boards
Start by marking the boards where you want the fingers to be. The width of the fingers should be about 1/3 to 1/2 the width of the board. The space between the fingers should be about 1/4 the width of the board.
2. Cut the Fingers
Using a hand saw or miter saw, cut the fingers at a 45-degree angle. If you're using a router, you can create a jig to ensure consistent cuts. Be sure to wear safety glasses and ear protection when using power tools.
3. Test Fit the Boards
Before applying glue, test fit the boards to ensure the fingers interlock correctly. Make any necessary adjustments with a chisel.
4. Apply Glue
Apply wood glue to the fingers of one board, being careful not to get glue on the face of the board. Then, apply glue to the corresponding fingers on the next board.
5. Assemble the Joint
Assemble the joint, using clamps to apply even pressure. Wipe away any excess glue with a damp cloth.
6. Allow the Glue to Dry
Allow the glue to dry according to the manufacturer's instructions. Once dry, you can sand and finish the joint as desired.
Variations of the Herringbone Glue Up
The herringbone glue up can be varied to create different patterns and effects. For example, you can create a herringbone pattern with wider or narrower fingers, or you can create a pattern with alternating directions.
You can also use the herringbone glue up to create complex joints, such as the mitered corner joint used in cabinetmaking. By creating interlocking fingers on all four sides of a corner, you can create a strong, stable joint that is resistant to racking.
Tips for a Successful Herringbone Glue Up
| Tip | Description |
|---|---|
| 1 | Use fresh, sharp tools to ensure clean cuts. |
| 2 | Clamp the boards together tightly to ensure a strong bond. |
| 3 | Allow the glue to dry in a cool, dry place to prevent warping. |
| 4 | Practice the technique on scrap wood before attempting it on your project. |
