I occasionally cut plastic extrusions into short lengths on a chop saw. Since this makes a fairly big mess of plastic sawdust scattered over a large area, I've done this just outside a rollup door, where I can drag a table, an extension cord, and an air hose fairly easily.
However, my building manager recently rented my work area out to another tenant who is storing pallets of material there. I can easily do the job inside, but the mess would need to be contained to a smaller area.
Any ideas for a breakdown containment system that is inexpensive to make, sets up and breaks down easily, and can be stored in a small space? I have one wall to work with, but can't fasten anything to it.
