Spray painting is a problem. I don't like overspray getting on things, tools, the floor, walls etc. I don't like the fumes. And there must be a way to control it. Requirements are the paint booth must have good suction airflow to control overspray. The booth most fold up and be able to be put out of the way. Booth must be big enough for longer and bigger parts. This booth is two boxes with a 4X8 sheet of concrete wire. The wire holds the parts so spray go fly past instead of bouncing off. And I can use small grid if needed for smaller parts. I buiilt this box with a fan thinking it would suck the fumes and overspray. I used a furnace filter to catch overspray before it hits the fan blades. I thought about using my vacuum system, but I don't want to suck paint into it, and I didn't think the 4 inch pipe would create enough airflow. This is work in process. It does kind of work. Notice the blue paint on the furnace filter. The findings of this first test are: 1) the walls on all four sides don't allow me enough access to the parts to paint them. The single exhaust fan is not sufficient to suck enough air for the whole booth. The cardboard does seem to work. Next I will add more fans, cut off one side of the boxes, land ower holding grate down a bit. See next entry.

Furnace filter does catch the spray. See the blue?
