Unless you have a fully-enclosed router table, your chip and dust collection probably leaves something to be desired. Instead of fully enclosing the entire table, Rockler’s Dust Bucket just encloses the router to get the same level of dust collection. When used in conjunction with a fence collection port, the Dust Bucket will allow you to collect virtually all the dust from your table.
The 13″ wide by 13″ high by 10″ deep galvanized steel Dust Bucket fits over most routers and is deigned to be used with a 4″ dust collection system or larger. It attaches to the underside of the router table with key hole slots. A door with a magnetic catch built into the front of the bucket gives you access for changing bits or cutting height, and an adjustable vent allows you to control the level of suction. The 4″ collection port can be mounted on the back or on either side of the bucket.
Rockler sells the Dust Bucket dust collection system for $80.
