Mortising base works on any plunge router
This auxiliary base for my plunge router makes mortises in all sorts of furniture parts. I made it from 1⁄2-in.-thick acrylic, slotting it to attach two pieces of T-track, which hug the workpiece to guide the router. You can saw, sand, and rout the acrylic like wood. The acrylic lets you see your end marks when routing, and the fences slide smoothly. I often clamp legs together in pairs to create a more stable surface, reversing the jig to cut matching mortises in both legs. For narrower stock, I attach the T-tracks to wood fences as shown to add stability.
