Make big sticks from little sticks
For this project, make short scrap longer by gluing it end to end. Rip short, wide boards into narrower strips, and glue the strips together to get at least 27" of length.
Clamp an end-to-end joint in a parallel-jaw clamp and let the glue dry.
Joint an edge of the glue-up while it is still in the clamps. Rotate the piece and joint other faces as needed.
Gluing other scraps alongside the end-joined pieces on the jointed faces reinforces the joint. If you’re attaching other end-joined pieces, stagger the joint lines.
