Keyhole Slot Routing Jig

Routed keyhole slots provide a great way to hang everything from picture frames and plaques to small cabinets. Plunging the bit into the work, and then moving it forward about 38" creates a keyhole-shaped slot that accepts the head of a screw. Here’s a simple jig to help with the job. It’s nothing more than a small panel of 14"-thick plywood or hardboard with a frame of fences attached to guide the router. The panel “wings” allow clamping the jig to a cabinet. For smaller workpieces, attach the panel with double-faced tape or hot-melt glue.
