Anyone who owns an economy router dovetail jig will attest to the mess of sawdust it creates. I borrowed this idea from a YouTube video I saw. I made a few improvements that made routing dovetails a whole lot smoother. The full extension drawer slide provides smooth transitions and the small shelf at the end provides a resting place for the router as pieces are swapped out. Along with my router with built in dust collection and the port under the table this jig collects 99% of the dust.
