I have the 1hp harbor freight dust collector and made a steel trash can dust separator/thien baffle for it. I modified the bag system on it by buying a 1 micron dust collector bag on Amazon. Unfortunately that bag did not fit, so I used my shapeoko to create an adapter from the 4 inch outlet to the 14" outlet that the new bag needed.
I’m still working on a new dust shoe design, but with the temp one I’m using, there is no noticeable dust in the air with aggressive feed rates in MDF.
This solution is very effective, and noise is not noticeable when compared to the router/bit in the material.
