I just made myself a spray booth over christmas. I made it from some 6mm MDF, an old kitchen worktop, some low voltage lights, an old battery charger, a car heater fan and some trunking from a clothes dryer
I dismantled the charger and used the transformer to power the car heater fan (from a Nissan). I split the heater fan casing and mounted the fan part behind the booth so it draws air through a hole in the back wall. It blows the air out the cloths dryer hose which I can dangle out of the window behind where the booth sits. There's about a three inch gap in front of the back wall then theres a proper spray booth filter material supported by some steel mesh. I got the filter stuff from a friend who works in a proffesional paint shop.
I'd like to add some better lights to it eventually but it'll do for now. Ideally it would be great to have a small flourescent tube on each side as well as the lights above. I may also paint the inside of it white to reflect the light around a bit. The heater fan really shifts a lot of air..possibly too much. If that's the case I'll vent the gap behind the filter with some kind of adustable vent to create an air leak. I haven't had a chance to use it yet as I only finished it today
Here's some pictures of it...
With the filter out...
The fan (the clamps are just holding it together while the glue dries)....
The pipe hanging out the window...
