The Dewalt router in my X-Carve CNC discharges its cooling air downwards towards the cutter which makes a Dust Boot (or shoe) essential. I have created a simple Dust Boot which can be easily fitted or removed. I have used loose bristle, kindly supplied free of charge by a major UK brush company, and show my experiments with different diameters of bristle and different glues.

Here is a link to the makers:
