Now that it's a the dead of winter its too cold to paint outside and painting inside the garage doesn't work because of the fumes so I built a downdraft paint table for my basement workshop. I put it in my basement shop mainly because I don't have any way to vent the fumes if I were to put it in the garage. I also had some unused space in the shop so it wouldn't be in the way.
Copying what other builders have done I used one of the two crates that the wing kit came in. It was too long to fit in the designated spot so I cut it down to 60 inches long and moved the end piece to close out the box. Then I added a 4" duct inlet, 24" square furnace filter and some wood and pegboard I had laying around. To vent the paint fumes outside I bought a boat bilge vent fan from West marine and 12V power supply from Radio shack. I built a wood frame to fit in the window over my work bench to exhaust the fumes outside.
Based on initial tests it looks like it's going to work well. I still need to put up some wood or cardboard to protect the walls from paint and make a grid to sit on top of the table to hold parts while they're being painted.
