Shop-Built Router Jointer

We'll show you how to build a unique benchtop accessory that converts a common router and a flush trim bit to a powerful jointer tool.

Transform your router into a precision edge-jointing machine with this clever, shop-built router jointer plan. Using just a router and a flush trim bit, you can achieve perfectly straight, smooth edges on your boards—without the need for a full-size jointer. This compact, cost-effective solution is ideal for small shops or woodworkers looking to maximize space and efficiency.

The jointer base is made from 3/4" plywood and includes just a few parts: a stable baseplate, a tall laminated fence for smooth gliding, and angled braces for rock-solid support. The design features a dust-relief recess and strategically placed mounting holes for easy router setup. With clear instructions and smart construction techniques, you’ll get pro-level results using tools and materials you already have on hand.

Whether you're prepping panels for glue-ups or fine-tuning stock edges, this router jointer offers precise, repeatable cuts in a footprint that fits any workshop.
