Miters are not the strongest joints, but we use them all the time for joining picture frames together.One method for strengthening this connection is to add a spline, a thin sliver of wood into a slot where the two miters join together.
A common way to make these is to cut a slot about halfway through the corner after gluing the frame together and slide in the spline.Standard spline that goes halfway through the miter.A BETTER METHOD FOR MAKING SPLINES In this method, the picture frame and the splines are glued up all at the same time.
These splines are stronger because they run all the way through the width of the miter and the grain is positioned to run perpendicular to the miter.Making the slot-cutting jig is simple.It's basically the opposite of my regular spline jig.
Regular slot cutting jig (left) and alternative jig.MAKING THE SLOT-CUTTING JIG Glue together two scraps of plywood.One a little taller than your rip fence, and the other piece square.I added a couple screws so I wouldn't have to wait for the glue to dry.
Next, square this assembly up by cutting off the bottom triangle of the square, shaving off a little of the...
