Gluing wood edge to edge, often referred to as edge joining or edge gluing, is a common woodworking technique used to create wider panels or boards. Here's a step-by-step guide on how to glue wood edge to edge:
Materials and Tools:
Wood boards: Ensure that the boards are straight, flat, and have clean, square edges.
Wood Glue: Use a high-quality wood glue suitable for edge joining. Polyvinyl Acetate (PVA) glue is commonly used for this purpose.
Clamps: Choose enough clamps to apply even pressure along the length of the joint.
Biscuits or dowels (optional): For added alignment and strength, you may use biscuits or dowels.
Procedure:
Prepare the Wood:
Ensure that the edges to be joined are straight, smooth, and free from defects. Square the edges using a jointer or table saw if necessary.
Dry Fit:
Place the boards edge to edge to check the fit. Ensure a tight and gap-free joint. If using biscuits or dowels, mark the locations for the joinery.
Apply Glue:
Apply a generous and even layer of wood glue to one of the edges to be joined. Use a brush or roller to spread the glue evenly.
Insert Joinery (Optional):
If using biscuits or dowels, insert them into the glue along the edge.
Align the Edges:
Bring the two edges together, aligning them precisely. If using joinery, make sure the biscuits or dowels fit snugly.
Apply Clamps:
Use clamps along the length of the joint to apply even pressure. The clamps should be snug but not overly tight, ensuring that excess glue can escape from the joint.
Wipe Off Excess Glue:
While the glue is still wet, use a damp cloth to wipe off any excess glue that may have squeezed out. This helps prevent glue residue on the wood surface.
Check for Alignment:
Ensure that the boards are aligned and that there are no gaps in the joint.
Allow to Dry:
Allow the glued joint to dry according to the glue manufacturer's recommendations. This typically ranges from a few hours to overnight.
Remove Clamps:
Once the glue has fully cured, carefully remove the clamps.
Trim and Finish:
If necessary, trim any excess material from the edges, and then finish the surface as desired.
Following these steps and using proper clamping techniques will help you achieve a strong and reliable edge-to-edge glue joint in woodworking.
