When gluing up stock, which statement correctly describes the glue distribution?

• A. A single bead at the center
• B. No beads are used; apply a full coat
• C. Small beads of glue along the joint
• D. Glue only at ends

Answer: (C)

When joining boards, you want adhesive coverage across the entire mating surface without creating a pool of glue. Small beads along the joint give you just enough glue to coat the surface as the boards are pressed together, ensuring a strong bond and controlled squeeze-out. A single bead in the center wouldn’t reach the entire length of the joint, leaving portions without adhesive and risking a weak, misaligned bond. Applying a full coat or no beads both lead to too much glue, which can squeeze out excessively, cause mess and warping, and complicate clamping. Gluing only at the ends leaves most of the joint without adhesive, also weakening the assembly. The idea is to provide even, adequate coverage along the joint with a thin, consistent layer.
