Yes and no - he was talking about installing the window - be Ethan did it in a rubbermaid "Brute" trash can! I thought that was novel!
Consistent with the title of this thread, it is, in fact, a
32-gallon Rubbermaid Brute.
However, keep in mind that anything short of very stiff/strong plastic or heavy metal/fiber board will require reinforcement for use in any vacuum system... While a DC generates far lower static pressures than a Shop Vac, the DC's static pressures can prove more than sufficient to collapse an unreinforced container, especially if all the blast gates are momentarily closed (or blocked, etc.).
Fortunately they are not terribly difficult to reinforce. Most containers will need either one or two reinforcing hoops, most easily made from 1/8"x3/4" aluminum bar extrusion available from most home improvement centers (e.g. Lowes or Home Depot). A really lightweight container might need a third hoop, but I would expect that to be rarely needed.
To calculate the length of the aluminum extrusion needed to create your reinforcing hoop just multiply the diameter (
D) of the barrel at the point you wish to install the hoop by
pi (i.e.
D x
3.142) -- this will be how long the bar needs to be in total (plus a few inches of added length for the overlap so you can rivet the two ends into a closed loop. If needed you can rivet two such bars together to get a longer length. Then simply form them into a round hoop by hand, rivet the two ends together and then rivet the hoop to the barrel so that it can not move or become dislodged. If your container is flared (i.e. not perfectly vertical) at the point where you want to locate the hoop it can be helpful to add just a little extra length so that you can press the hoop into position for a tight fit before riveting it to the barrel permanently.
One or two such hoops (at about 1/3rd and 2/3-to-3/4 height depending upon stiffness of the top opening) will pretty well ensure that most barrels will not collapse under the vacuum pressures seen in a DC system. In the case of the Rubbermaid Brute trashcan I only needed one such hoop because there is a stepped edge near the handles that greatly stiffens the top half of the trashcan so no reinforcing hoop was needed for the top half.
My 32-gallon Rubbermaid Brute trashcan is incredibly easy to carry (even though disabled I can easily handle it) outdoors even when filled to the brim with sawdust from dense hardwoods -- and it even included a convenient lid that I can place over the can while I'm transporting it so that I don't have to worry about stirring up the dust.
HTH
PS - I used 1/8"x1/4" aluminum rivets... and if you opt for rivets as well and make a mistake, you can undo your mistake by drilling out a bad rivet with the same 1/8" bit you used to drill the original pilot holes for the rivet (i.e. rivets are no more permanent than screws, just less likely to work loose over time).
