A Simple Dovetail Key Jig

Dovetail keys add strength and beauty to an otherwise ordinary mitered corner. To make this handy jig, simply follow the three-step process shown at right. After the jig is constructed, determine where to set the fence on your router table

order to put the keyways exactly where you want them. But before you chuck your dovetail bit in the router, use a 1/4" straight bit to plow a groove in the jig (to remove waste material). Switch to your dovetail bit and remove the remaining material. Slide the jig along your router table fence to form perfect dovetail keyways.

Form two identical rectangles from 1/2" plywood or MDF. The blanks must be perfectly square. Glue and clamp the blanks together.

Set the blade of your table saw to exactly 45' and cut the glued-up blanks in two. Flip one piece over as shown above.

Cut jig sides from 1/2" hardwood and form a 45' ramp, too. Position the pieces as shown above and secure them with glue, but no screws or nails.
