How to Glue Solid Wood Edging With Wood Glue?

To glue solid wood edging with wood glue, prepare the surfaces, and apply a thin layer of glue to both the edging. Press the edging firmly against the wood, ensuring proper alignment. Clamp the pieces together and let the glue dry. After drying, the joint will be stronger than the wood itself.

Joining smaller pieces of wood to create larger panels is common in woodworking. It helps create wider boards that are not naturally available.

In this article, I will guide you through our edge gluing process. It is a fundamental skill that every woodworker should learn.

Considerations for Edge Gluing Boards

When edge gluing boards, there are several important considerations to remember to ensure a successful and strong bond between the wood pieces.

Properly preparing your stock is critical before embarking on the edge gluing process. By following these steps, you can ensure a successful and reliable glue-up.

Start by cutting your wood pieces to the desired length. This initial cutting step is essential to ensure that the panels you create are of the correct size and dimensions for your woodworking project.

When preparing the faces that will be glued together, it is crucial to have one face perfectly flat and at a 90-degree angle to the edges.

Creating true surfaces is another critical factor in achieving a tight joint line.

Any irregularities or unevenness in the surfaces can compromise the integrity of the joint.

Another factor to consider, especially when working with flat-sawn wood, is the arc of the end grain.

Flat-sawn wood often exhibits an arc or curve in its end grain, potentially leading to warping issues in the final panel.

To mitigate this, it is advisable to alternate the direction of the end grain arcs when arranging the wood pieces.

Doing so allows you to distribute any potential movement more evenly, reducing the risk of warping and ensuring a more stable and durable panel.

Taking the time to prepare your stock properly sets the foundation for a successful edge gluing process.

It helps create a strong bond, minimizes potential issues such as warping, and ensures that your final panel is high quality and meets your project requirements.

Preparing The Wood Stocks

Technique 1: Table Saw Method

The table saw provides a straightforward approach to achieving accurate edges for edge gluing panels. Follow these steps:

  1. Set up the table saw and mark the boards for identification.
  2. Rip each board, one at a time, ensuring a clean and straight edge.
  3. Once the edges are prepared, apply an even coat of glue on both surfaces using a spreader, brush, or fingers. Make sure the glue covers the full face of the edge.
  4. Place the boards together, ensure they align correctly, and apply enough clamping pressure to bring them firmly together.
  5. Check for a thin bead of glue along the joint line, indicating the proper amount of glue and ensuring a flush alignment.
  6. Use additional clamps to align the joint line accurately, minimizing the need for extensive planing and surfacing after the glue dries.

Technique 2: Jointer Method

A jointer is a specialized tool designed explicitly for creating clean edges for joining wood pieces. Here’s how to use a jointer effectively:

  1. Prepare the boards by marking them for identification.
  2. Set the jointer with the in-feed table and the out-feed table aligned.
  3. Join the boards individually, keeping the edge on the in-feed table for the initial portion and gradually shifting pressure to the outfeed table. This ensures that the jointer’s cutter head flattens the edges evenly.
  4. Continue jointing until both boards have clean, jointed edges. These edges should form a tight seam with no visible gap when they come together.
  5. Apply glue evenly to both jointed edges, ensuring full coverage.
  6. Align the boards, apply clamping pressure, and check for glue squeeze-out along the seam.
  7. Clean up the excess glue with a damp cloth or sponge while still wet.

Factors to Consider

Composing the Panel

Several factors contribute to a successful glue-up when assembling the boards to create a panel.

Alignment is crucial for achieving a seamless joint. Utilize alignment marks or reference points to guide the arrangement, ensuring precise alignment of the boards.

Maintain even spacing between the boards. This equal distribution of pressure during clamping prevents the boards from exerting excessive force on the glue joint, promoting a balanced and secure bond.

Thoroughly inspect each board for defects or imperfections before gluing. Address and repair any issues to uphold the overall quality of the panel.

Gluing Process

To ensure a successful glue-up, begin the gluing process only when everything is prepared and within reach, including clamps, glue, and necessary tools.

Working swiftly minimizes the risk of glue drying before clamping.

Apply an even layer of glue to the prepared surfaces, utilizing a spreader, brush, or fingers.

Ensuring full coverage of the face of the edge promotes a strong and reliable bond between the boards.

Align the boards accurately and apply clamping pressure to bring them firmly together.

Distribute the pressure evenly across the boards to maintain consistent and uniform bonding.

Check for squeeze-out along the joint line, indicating adequate glue coverage, and promptly remove any excess glue.

Monitoring the clamps during the drying process is essential.

Periodically check their tightness and security to prevent shifting or misaligning the boards as the glue cures.

Handling Glue Squeeze-Out

Immediately clean up excess glue while it is still wet using a damp cloth or sponge. This prevents dried glue from interfering with subsequent finishing processes.

Exercise caution to avoid smearing the wet glue across the wood’s surface. Smearing can lead to unsightly glue stains that are challenging to remove.

After the glue has dried, carefully scrape any remaining residue using a chisel or putty knife.

Finishing Touches

Once the glue has fully cured, you can proceed with further machining or sanding the panel.

Allow sufficient drying time for the glue to cure completely before proceeding. This ensures the joint’s integrity remains intact.

Inspect the panel for any imperfections or irregularities after machining or sanding.

Address these issues accordingly to achieve a smooth and even surface, ready for finishing or subsequent woodworking operations.

Final Thoughts

Mastering the technique of edge gluing is essential for any woodworker.

Following the tips and techniques outlined in this article, you can achieve strong and seamless joints in your solid wood panels.

Remember to work precisely, maintain a clean workspace, and practice patience for optimal results.

Frequently Asked Questions

What kind of glue to use on wood edging?

For wood edging, it is recommended to use a high-quality woodworking adhesive such as a PVA (polyvinyl acetate) glue or specialized wood glue. These glues provide strong adhesion, flexibility, and durability for edge gluing applications in woodworking projects.

How do you glue wood together with wood glue?

To glue wood together with wood glue, start by applying an even layer of wood glue onto the surfaces that will be joined. Next, align the pieces carefully and apply clamping pressure to bring them firmly together. Wipe off any excess glue with a damp cloth. Allow sufficient drying time for the glue to create a strong and durable bond between the wood pieces. Wood glue is an excellent adhesive choice for woodworking projects, providing reliable and long-lasting results.

How do you glue wood edges?

To glue wood edges, apply a layer of wood glue to the mating surfaces of the wood edges. Align the edges and apply clamping pressure to bring them together. Wipe off excess glue and allow proper drying time for a strong bond. Wood glue is ideal for joining wood edges securely.
