1 Powered by a 12 volt DC Wall Wart This documents my experience in designing and building the paint booth. I indicate where I found and purchased the materials and note options I considered as I progressed. Page 1 of 7

2 This is a list of the materials I used and where I bought them. You might already have some of this or other similar materials laying around that can be used, thereby making the project cheaper. If you can find it, use GatorFoam board --- it is a little pricey, but you wont be able to beat it for strength and light weight inch by 60 inch by ½ inch white Foam Board Texas Art Supply 3-½ inch 12 VDC 0.30 amp Electronic Parts Outlet 5-½ inch round 6 VDC white LED camping Electronic Parts Outlet Iluminated Rocker Switch with Red LED 12 VDC RadioShack 12 VDC 1.5 amp AC-to-DC power adaptor RadioShack ga solid Hookup Wire RadioShack Liquid Nails 2.5 oz Clear Silicone Adhesive Home Depot 3.97 Air conditioner filter x 25 x 1 FPR 7 Home Depot Air conditioner filter x 25 x 1 FPR 10 Home Depot Total RadioShack also has 12 VDC brushless fans. They are little more expensive at half the power but they should work fine. I find that I have a pretty significant flow from the two fans, even with the two-stages of filters. You might find that one fan would be adequate. I liked the camping lights because they run off 4 AA batteries (6 volts) making it easy to wire two of them in series to add to the 12 VDC system. I placed two disposable air conditioner filters in series. The first one grabs most of the paint particles, the second gets the rest, even bacteria. Even the odor from lacquer and enamel paints is mostly stopped. Materials Page 2 of 7

3 I found that Texas Art Supply had this 40 by 60 piece of ½ inch board in stock, but they do not list this size on their web site. Two 30 by 40 pieces can be used but as you can see, the back would have to be glued from two pieces (14 x 25 and 2 x 25) no big deal. I made my paint booth for my other home from two smaller scraps of GatorFoam board I got from a sign making company. After experimenting with dimensions, but still using the standard 16x25x1 filters, I was able to make the booth 24 inches deep.

6 I used 12 volt DC fans run from an AC-to-DC power adapter for safety. I added two 6 volt white LED light assemblies in series and wired them to the 12 volt system. I soldered the wires to the switch and the light assemblies. I plugged the 22 gauge solid wire into the fan connector sockets. The lights, fans, and switch were glued to the foam board with Liquid Nails.

7 Assembly Instructions The GatorFoam should be cut with a sharp utility knife with cuts as perpendicular as possible using a metal straight edge for a guide. Using a table saw with a fine blade would be better. Measure, mark, and cut out pieces. Cut holes for the fans, switch and wire. Carefully measure and then glue the filter supports to the top, bottom and sides. Glue the fans to the back. Place books on filter supports and fans and let dry overnight. Insert and tie the power supply wire through the right side and glue. Insert the wire back through the switch hole and solder to the switch. Cut two red and two black wires for the fan (6 inches long). Cut one red and one black wires for the light (40 inches long). Cut one green wire to connect the lights (6 inches long). Solder the fan and light connecting wires to the switch. Insert the fan and light wires through the switch hole and glue the switch to the right side. Solder the light connecting wires to the lights. Assemble the box upside down (don t get confused by the following instructions): Glue the pieces with Liquid Nails in the following order: Glue Back to Top (bead of glue on top of Back). Glue Sides to Top and Bottom (bead of glue on top of Sides and sides of Back). Glue Bottom to Sides and Back (bead of glue on bottom of Sides and Back). Glue lights to the Top. Place books on Bottom around the Sides and Back and let dry overnight. Plug wires into fan connectors. Insert filters, sealing each around the edges with tape. Tape clear plastic wrap over the lights to keep them from being painted. Instructions Page 7 of 7
