I've been reading all the threads and did some searches on the Thien separator/cyclone. I'm interested in building this, but have a 3 hp, Grizzly 1030 DC.
If I use a 30-50 gallon drum, would this type of system work? There's a fair amount of suction on the 3 hp motor, and I don't want to go to the work of building a lid and then not having it work. (I have both metal and fiberboard drums, both with sealable lids.) Anyone have any experience in using this on a larger system? I have 6" main duct and would use this in front of my DC.
Any thoughts?
