After many years of using a single stage then upgrading to a 2-stage trash can collector. I’ve finally upgraded to a Dust Deputy cyclone. My original DC filled the air with dust every time I turned it on and it wasn’t very air tight. My dust collector is a 2HP Woodworkers Warehouse Reliant NN-820. The spec sheet says it’s capable of 1185 CFM’s with 5” ports and the motors heavy, really heavy.

My design is based from kdc68’s design:

Next step is to secure the 10 gal bucket to routed groove in the cover. I’m planning to use threaded rod secured with plastic thru-knob handles which will raise the board below the bucket and hold it tight. After that I need to find a cartridge filter. I’d like a cartridge filters from Wynn Environmentals but they’re expensive. As an alternative I’ve been researching truck air filters, the kind you see on 18 wheelers to see if something like that might work and be less expensive. My idea is that I could stack several filters to get maximum filter density. I know automotive filters aren’t Merv rated but with the addition of the cyclone there should be very little dust exiting. I’d appreciate any comments on that.
