   Mine is actually made of cardboard and 1x2 lumber for the frame. It folds somewhat like an accordion so it becomes really compact. The fan with the best CFM I could find was not a box fan. However in came in a box so I simply cut two large holes in the box for the suction and exhaust of the fan. I keep the fan in the box at all times. I taped a furnace filter to the intake side of the box. I used the type of filter that only picks up large particles so it does no clog with finish. On the exhaust side I made a square duct out of cardboard. Using a couple of 2" styrofoam sheets I make a temporary wall that fits perfectly in my garage door opening. That wall has a square hole into which the fan's exhaust duct fits pretty tightly.
   This way all the fumes go outside and rain and snow don't come in while I am spraying.

   I don't have photos handy but if you want I can take some and post them.

   Forgot to mention the turn table, which is a very important aspect of the setup. I copied the design for mine from a video I found on the web (cannot find it anymore):

   - Use a piece of sheet good for the base. Something like 3'x3'or larger. Screw a flange on it to accept a 1 1/4" outside diameter threaded steel pipe.
   - For the table, glue/nail/screw two layers of 3/4" sheet good and cut into a circle about 24" in diameter. Screw a flange on the underside of the table to accept a 3/4" outside diameter threaded steel pipe.
   - Cut a piece of 1 1/4" threaded steel pipe, about 30" long, and thread it into the base flange.
   - Cut a piece of 3/4" threaded steel pipe, less than 30" long, and thread it into the table flange.
   - Insert the small diameter pipe inside the bigger pipe. This does not make for a very precise bearing but it is very strong and the table turns effortlessly.
