To glue up and clamp an edge joint, you will need to follow these steps:
1. Make sure the edges of the boards are straight, square, and free of any debris. If necessary, joint the edges to ensure they are flat and straight.
2. Apply a thin, even layer of wood glue to one of the edges.
3. Align the two edges together, making sure they are flush and the joint is tight.
4. Apply clamps to hold the joint together. Start with a clamp at each end and then add additional clamps as needed to ensure the joint is tight and secure.
5. Wipe away any excess glue that may have squeezed out of the joint.
6. Allow the glue to dry completely before removing the clamps. The drying time will vary depending on the type of glue used, so be sure to follow the manufacturer's instructions.
7. Once the glue is dry, remove the clamps and use a hand plane or sandpaper to smooth out any uneven areas in the joint.
By following these steps, you will be able to glue up and clamp an edge joint successfully.
