Photobucket is back and here's pics of my spraybooth.
The cart came from Harbor Freight or Northern Tool (don't remember which), compressor, light fixture, exhaust fan from Lowe's. I wired so there's an extension cord to plug in and that provides power to the 4 switched receptacles (light, fan, compressor, spare). It's modeled after the large, expensive Pace unit but not as expensive. I cut a hole in the shop wall and mounted a dryer vent and attached the 4" hose. On the booth side I used a PVC fitting to attache the hose to and notched the PVC to latch onto bolts on the fan housing.
