Router Jig for Flush Shelf Edging
Here is a router jig for trimming edge moldings flush with a flat surface. I have used this jig for trimming the edging on tables and countertops, but its most useful role is trimming solid-wood edging on plywood to be used as adjustable shelves for bookcases.
The jig consists of two wood blocks screwed to a hardwood router sub-base. A 3/4-in.-dia. flat-bottom router bit is set to cut flush with the 1/2-in.-thick block that rides on the surface of the plywood shelf. A 2-in.-thick block acts as a guide to run along the front of the shelf edging. Run the router over each face of the shelf to trim the edging flush with the plywood surface.
To save time when edging the shelves, I rip a 7/8-in.-wide, solid-wood strip that’s about 1/8 in. thicker than the plywood. Then, I glue up a sandwich with the solid-wood strip…
