Mini spray booth?

[...dave]

The goal: rattlecan small objects (intake manifold and smaller) in a VERY crowded 2-car garage without getting overspray on white car, motorcycles, tools, stray cats, etc., without spending an hour moving everything out into the driveway beforehand. Must be compact, and not require frequent replacement.

Current solution: stick object on large sheet of cardboard, place in middle of lawn. Remove bugs and lawn clippings between coats.

Not optimal.

Maybe a solid frame on a lazy susan, with hinged sides to access the item from different angles? Anyone have a good solution that they're already using?

Not sure if you have a window in your garage, but I use a powerful window fan on the exhaust setting to **** out overspray. Mind you this would not be a good setup for true painting using a compressor, but it works great for painting with spray paint cans.

I just set up a desk with newspaper on it to paint right in front of the window fan and it ***** everything out immediately. Just be sure there is nothing important on the other side of the window (like a house).

Here is a small cheap one on ebay also... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=28111&item=8175437835&rd=1#ebayphotohosting

Spray Booth

There is a great little Spray Booth project in the Ultimate Garage Handbook on page 56 / 57 where they built a frame and mounted an air filter from an a/c unit and a small fan ( sealed unit safe for flammable or explosive vapors) They then built a box frame from PVC piping and shrouded it with plastic for a quick small spray booth that can be dismantled and reassemble'd easily.
Hope this helps.

I will make a wooden box with light when I get a chance as I have some room and lots of scrap wood.

So the key to avoiding overspray is ventilation, eh? Hm... that will require some thought. i have no windows, so i guess i'd have to go through the wall with a dryer vent-type deal and duct it. Any good resources for just a fume-safe fan?

I learned something about venting paint fumes after reading about someone's idea of piping the exhaust through water.

I never did get a good explanation of that, but I asked my Dad, who is a retired stationary engine and was a plant maintenance supervisor at a boiler factory what he thought. He told me that it wouldn't really work but that the most important thing to NOT shoot out into the air are the solids or sediments from paint. The environmental folks don't care about the smell.

So the trick that they used at the shop was to pipe the exhaust through a flex hose and put lot of vertical bends in the hose. That way the air flow would have to bounce off of the inside of the hose several times before exiting. When it does that, the paint in the exhaust air hits the hose and the amount shot out into the air is greatly reduced. Having the bends go up and down instead of side to side took advantage of gravity to help the solids drop on the down turns. Al they did was run those over a series of work horses. Usually, at least three drops but more if they could.

I know that's supposed to be the job of the filter, but they had to do this in addition to the filter in order to get the emissions down. According to the inspector anyway.

It's something to think about - especially if the exhaust hose is pointing at your neighbour's house.

Oh and after reading this thread, I ran out and bought that Ultimate Garage Handbook. Not bad. I like the paint booth idea. There's some neat ideas for storage as well.
