I have a small one made the way lanwater explained (pipe and pipe flange) it’s on a mobile base, and the table is about 2’ square. Larger stuff just gets stood up, or maybe laid down on a set of plastic horses. Once I was spraying a lot of base board and door casing. Using NC lacquer, I was spraying outside, so I took a pair of saw horses and screwed some furring strip to them that were angled back about 45º. I put rows of nails in the strips and laid the trim on it to spray.
