In-the-bag solution to elusive router-table sawdust
The dust port on a router-table fence collects most of the dust above the table, but some still escapes below. To keep that debris off the floor, I built a lightweight poplar frame, large enough to fit around the router, with ample room for cooling air. I tacked fabric around the sides and bottom of the frame. Rare-earth magnets mounted to the top of the frame attach to metal washers on the underside of the router table. The collector catches all falling debris and detaches easily for emptying. Note that I left room for the cord to exit the collector by leaving a gap in the frame at each corner. That way, no matter how you replace the collector, there's a notch positioned for the cord.
