video Dust "Shoe" for Drawerslide CNC
After building a somewhat inexpensive drawerslide CNC machine I was dealing with a lot of wood dust when working on projects.  Most DIY CNC machines can hold a dust shoe that is pretty straight forward.  The machine I built didn't lend itself to any dust shoes that I could see.  So I built a  simple attachment that seems to work pretty well.  

Thanks for watching.
