Easy Edge Trimming

By: Logan Wittmer
I prefer to put the edging on my plywood cabinets after they’re all assembled and then trim it flush with a router. But I needed a way to support the router and be able to cut into the corners. This jig solves both problems.

The jig is easy to use. Just place the baseplate on the edging surface and feed it into the casing until the jig face contacts the surface of the workpiece. The little bit of wood left inside the corners can easily be cleaned up with a chisel. The jig works equally well on the outside cabinet surfaces and prevents rounding off the corners, too. Trimming plywood edging is a whole lot easier now.

It’s constructed so the router bearing on a 1⁄2" flush-trim bit lines up with the two adjacent faces of the jig. The faces ride against the surface of the workpiece to keep the router stable. A dowel provides a handle for a good grip. And a notch under the top allows for the edging overhang.

To build it, I cut the pieces for the top, bottom, and faces from plywood. Next, cut a rabbet for the recesses on the faces and then glue and screw these parts together as shown. After cutting the router baseplate, mark and drill the mounting holes using your router as a template. Then mount the baseplate drilling the holes a little over-sized to allow for adjustment. The router is positioned so that the bit bearing is perfectly flush with the two jig faces.
