Miter with Muscle

 

Gluing end of board
Glue it right

End grain looks and acts like the end of a bundle of tubes—some solid areas among a lot of openings—so it sucks up glue. Improve your chances of making a strong mitered joint with woodworking glue by generously brushing glue sizing—one part glue mixed with three parts water—onto the joint faces to seal them. After the sizing dries, glue the joint, as usual.

Epoxy works well for gluing mitered joints and doesn't require sizing. Beware of quick-setting epoxy if you are gluing several joints at once; allow enough open time for assembly.

Whichever adhesive you choose, always clamp mitered joints for the full cure time recommended by the glue manufacturer. Remember that cool temperatures increase cure times.
