Well, life happpens I guess and I have not worked directly on the project for 16 months. In that period I did build a down draft paint booth of basically my design. I saw a somewhat similar downdraft table using a fan and filter and expanded this to a hooded paintbooth with an exhaust plenum and 10" exhaust duct that I can run under my hangar door and hopfully spray away. Unproven at this point but will edit this posting when it goes into service. The sides and back all fold down with the top creating another table/bench when not being used. Spent many hours learning SketchUp software to design this booth and for the most part it was built from the desgin which all worked extremely well.
