Abstract
An interlocking joint for joining two panels together has curved jigsaw shaped indents and protrusions on edges of both panels that fit together and cannot pull apart. The indents and protrusions are cut by a router with a straight sided cutter. A template is provided for guiding a bushing on a cutter shaft of a router and the template takes into account the bushing having a larger diameter than the cutter. There is also a jig provided that has fingers that are asembled to cut out the interlocking joint with a router.
