Spray Paint Box

DOG Aviation has added a spray paint station to the facility … finished most of the spray box yesterday and put the finishing touches on it today. Should have had it done by now, but had a lazy day on Sunday … found it hard to pull myself away from a book that had a good storyline.
                                 The spray box is 6’ x 30” with wire mesh across the top and has
                                             two box fans that should pull most of the overspray down through
                                             two furnace filters.

The fans are the inexpensive 3 speed fans typically found in discount stores.  I tried to find used fans at Goodwill and Salvation Army stores but it was not to be, so had to opt for new fans. The good thing is when the weather gets hot and humid, at least there will be two fans available to help make the shop bearable.

                                              Both fans just slide into slots under the spray box along with the filters.

Return from the future – A few thoughts. Although very pleased with the spray box in general, there is room for improvement. First- the wire mesh should NOT be chicken coop wire because smaller parts want to fall into the box and larger parts tend to snag the wire. Feel a better choice would be to use a wire cloth with a tighter weave. Second- the top should have a frame on a hinge so it can be flipped up for easy access to the inside of the box for clean out … buildup inside the box tends to occasionally fly back up and get on the work. Also if one wanted to go high tech, a few sheets of plastic or cloth could be stuck to the inside of the box and removed after the spray session. Feel this would virtually eliminate buildup from flying back out of the box.

The plan is to use PVC pipe to make a three sided enclosure around the spray box by hanging shower curtains from the PVC pipe. Because room is an issue, the box will sit on saw horses while in use then easily stored on its side when not in use. (Although I will admit the box weighs much more than I thought it would … half inch OBS is total overkill but it was inexpensive.) The PVC frame’s joints will not be glued so the frame can easily be disassembled. However, there will be holes drilled through the PVC joints with pins to keep everything secure while in use.
