I have build several Thien baffle separators and really like being able to adjust the design to fit the needs. I have a big one on my shop dust collector and one on a small mobile cart I use a lot.
Anyway, I'm finishing up a 4'x4' CNC router. It will have a dedicated dust collector and I'm going to make a separator for it. But I got thinking about how to reduce turbulence by have a straight inlet. I can cut arbitrary/complex designs on my CNC router and thought this design might be a step in that direction. This one is relatively small for a shopvac but I would size it up for the CNC DC. The top surfaces of the bottom ring and baffle would be coplanar, by the way.
A refinement of the design could be to use another strip of polycarbonate to support the outside edge of the 1/2" baltic birch top and bottom to make it look a bit more finished. Also thinking about integrating the baffle into the bottom. There may be a way to get rid of the supporting bolts which would serve to reduce turbulence and wind resistance (if that is the correct term).
I am interested in anyone's thoughts on this. Stupid idea? Needs work? Any gotchas?
