I have been needing to build a dust collection hook up for the CNC machine. In this project I used a modified version of the dust shoe that is on CNC Router Parts web-page. With the help of Nathan at CNC Router Parts, we made a design for a dust shoe with two 4" flexible hose connections. My hope was that with suction from two 4” hoses, I could get away without using the brush attachment. But I have found that the brush helps greatly in catching the dust and helping it up into the dust hoses.
