Cut Compound Miters Easily with This Tablesaw Jig

Here's a way to cut compound miter picture frames without an expensive compound mitersaw. Start by making an 18x28" base from a piece of 12 " plywood. Attach parallel miter-gauge guides to the bottom. Then, push this base through the saw blade to create a kerf that extends about 12" across the plywood.

Using this kerf as a centerpoint, screw the two fence pieces and the two angle blocks to the base as shown in the drawing. You can bevel the angle blocks at any angle you like, but 25° works well for most picture frames. Now, clamp or hold your picture-frame moldings against the fence and cut the compound angle by pushing the jig and the frame stock through the tablesaw blade.
