I was looking for a way to save some floor space by not having my Dust Devil bucket sitting on the floor attached to the shopvac. I used a 10′ section of PVC pipe and 4 end caps to make the legs and a piece of scrap 3/4″ board I I had laying around. The PVC pipe was cut to 30″ lengths and cut the board to 14″x14″ and mounted to the top of the legs with 4 lag bolts. Paint, roll, and Done!

At first glance thought you were going into the Shine business. Good ideas!
