4) I've purchased a 1200 cfm fan which will sit on top of the upside down trashcan. I will cut a hole in top of the trashcan and fan will pull air through hole and vent through flex duct and out the side of the house.

Why a trash can?

Virtually all non-metal trash cans are made of polypropylene. This is the most annoying substance on the face of the earth because absolutely no glue will stick to it except for an insanely-overpriced two-part epoxy from 3M that costs $120 per tube. JB Weld claims one of their products can glue polypropylene but I know from firsthand experience this is a lie.

Anyways. Don't try to make DIY stuff out of anything involving polypropylene, you'll be kicking yourself as soon as you realize you need to glue something somewhere.

I appreciate the suggestions to not use a trashcan, but unfortunately, I already purchased 5 saddled air-tite take-offs from home depot (which fit a cylinder shape). Also, the bottom of the trashcan is very rigid, and I wanted something really strong to hold the weight of the fan. Plenum probably could have served that purpose too. Anyway, I did find this Loctite glue for $3 at Home Depot. It does look like you have to use the activator first on polypropylene. Hopefully that works. If not, I will take back the trashcan and the saddled take-offs and go w/ plenum.
