I dearly love my Clearview 1800. Works great. In fact it works a little too good for my CNC. I have an Axiom, with a dust shoe that I made. It looks just like the factory item though. My problem is that the cyclone completely sucks the bristles from the shoe up into the 4" pipe. This is my second iteration of a dust shoe, both had the same problem. Does anyone have a better idea for a dust shoe?
