This was the basic concept used to sandblast inside a public library. I haven’t tried this for doing anything at high pressure, only for careful work with a gravity gun.

I used 1″x2″s for light weight construction, black plastic, and thin carpeting stretched across the top as the air inlet. The inlet should be sized so as to maintain a slight vacuum.
