I already have this dust boot and flexible vaccum hose hooked up to my cnc machine and going to a standard shop vac. The hose arm is by Rowdy Roman on etsy. This works fine so far but I find that I'm using a lot of vaccum bags. And at ~$10 a bag, that can start to add up. In order to combat that, I want to add a dust separator to this "dust collection" system.
