I have given up on the game of Twister I have been playing trying to fit 6" pipe around the existing HVAC, ect. in my basement/garage workshop.

I am resolved to digging a hole on the other side of my workbench in the dirt crawl space that will make room and fit the dust box under the cyclone and create the head room for the duct out of the cyclone to the side mounted blower. It is just the most straight forward way to get er done. Parsimony at work.

My next unanswerable question relates to how dust settles beneath a cyclone. My thinking is to dig a hole deep enough to place a box that will support the cyclone and give clearance for the exit pipe to the blower from the floor joists above. The lid of the rectangular box will be fixed in place under the cyclone to half the distance of the box. The other half will seal air tight but be removable.

My thought is to have a tightly fitting tall rectangular plywood container that slides into place under the cyclone inside this outer box. When it is in place I will close the lid on the outer box. When I need to empty the trash container I will open the lid to the buried box, slide the trash box out from under the cyclone to the open area and lift it out to empty.

My assumption is that as long as the overall box is sealed that the dust will fall into the trash box. I don't think there is a need to fill the rest of the space. I was also thinking that I could just zip tie a garbage bag to a pipe bolted to the outlet of the cyclone saving me the trouble of constructing another box within the buried box. But I am unsure about the behavior of a soft bag beneath the cyclone even if it is in a sealed box.

I tend to think a bit outside the box and wanted to do a reality check with more experienced sawdust practitioners. Is this going to work?
