Using a jigsaw fitted with a scroll blade, cut the outside edge of all four rings. For the insides of the rings that make up the lid, drill a ¼-inch hole into the area to be cut out, insert the blade, and cut along the circle. For the base, use the jigsaw to cut the space between the arms of the peace sign from the small ring. Center that ring on the larger ring of the base and use it as a template to transfer the pattern, then cut the larger ring. Apply wood glue between pairs of rings—centering the smaller rings on the larger rings—clamp them together, and secure them with ⅞-inch wood screws.
