Putting a picture in a nice frame can really brighten up your home (or make a good gift). If you really want a personal touch, you can build your own using your table saw.
For a simple decorative touch, it’s hard to beat half lap joints, when building picture frames or cabinet faces. Mortise and tenon joints are stronger, and pocket screw joints take less time to assemble. However, with a table saw and dado blade, you can bang out enough picture frames for every family member.
To make a half lap joint you need a wide dado blade to mill out enough wood from each part so the resulting joint is as thick as the frame. Attach the overlapping joint pieces together using glue. You can strengthen this joint using a pair of pegs or screws that are attached through the joint parts.
