joinery shop tip

Glue squeeze-out sometimes dries and adheres to the face of handscrew clamps. Later, projects that have been clamped turn out with marred surfaces because of dried-on glue globs.

Apply a coat of paste wax to the face of each jaw of your clamps to prevent glue buildup. It's also a good idea to maintain a light coat of wax on metal clamps—this will help you prevent rust from forming and discoloring project surfaces.
