I don't have one myself I do all mine on a multi-coloured bench well it was brown but I've heard of people buying a cheap plastic greenhouse from a poundstretcher type shop and using that outside and you can cut it down to any size.

Frank,

I do all of my spray painting outside and use Krylon spray paints. Often I have to spray in some wind, so I have learned to spray with the wind and use a very light spray pattern.

I have a 4x8 sheet of plywood set up on two saw horses, with an umbrella over head.  (Tip:  when spraying black do not spray paint in direct sunlight.  For some reason it will cloud up on you.) Then I use Styrofoam coolers with a cheap plastic turn table on top so I can turn the toy parts without touching them.

I buy Bar-B-Q sticks (at the market. 100 sticks for $1.98) to put my parts on so they are not setting flat on the turntable.

As you can see from the photo, if I want the toy part higher I just put a paint can on the cooler, then the turn table.

Spray three sides, lightly buff, and then spray the other side, lightly buff everything (in case of over spray). Then start over.  This I do until I have the finish I want.

Another reason to use the Styrofoam coolers and the Bar-B-Q sticks is you can punch a hole in the side of the cooler with the stick and hang parts up to dry.

My wife is an in-home care nurse and a lot of her patients' drugs are shipped to her or her patients in the coolers.  If you know someone in the home care field, they would be a great source for these coolers, and they are free.

The most important tip I can give you is not to try and get full coverage with the first spray coat. It is much better to go over and over a few times than to have sticky runs and drips.

If you are spraying in tight corners or curves, try bump spraying.  That its, tap the spray nozzle over and over again while spraying and moving over tight areas.  It is much easier to get an even coat with out runs with this method.   

A good resource for anything small is: http://www.micromark.com.  They have one fold up spray booth Item # 86104 that is on sale now for $99.95, and they have a 15 inch x 20 inch standard spray paint booth for there sale price of $307.90 (list price is $526.80)

I just bought a 7x7' plastic Rubbermaid garden storage shed for less than $200.00.  I am going to cut a hole in the back wall for a fan and put a 6' workbench as a spray stand.  Then I will be able to spray paint inside when the wind is to much to be outside.

These are just a few ideas that I have found very useful.

Thanks  Phantom and Ken for all these great ideas to munch on.
   I was thinking through this and thought to buy or make a cheap dog/ cat house and installing  a small fan to the back wall. I like your idea of the garden shed also Ken. Problem is I don't have room to keep it in my back yard. That's why I'm thinking about a dog/cat house or something small. Any pros and cons on that? As Phantom suggested maybe a small tent, too. I suppose I could adapt a fan in the tent wall somehow. Maybe even use a small cardboard box?? I wonder why I haven't seen these on my internet search. There must be a disadvantage.
   By the way what is the best kind of fan to use for a homemade paint booth jig? Any experience here? I think of it getting cluttered with paint eventually.
   Love your barb stick idea, too.

   I think you have the right idea about a dog house size structure.  You could leave off one of the long sides, and if it had a pointy roof you could then leave off the roof side where the open side is.
That should work great.  Good idea.
   Fan:  The only thing I have heard is you need to have a sealed motor housing type of fan, so you don't muck it up with paint, or start a fire with a spark from paints or varnishes.

Ken a great idea on the boxes and sticks I think I might buy some cheap Lazy Susans and try that method on a box with some triangle blocks to hold the job off the top.
This is what's good about this family of wood toy makers always happy to share ideas. stay safe.

YouTube has all kinds of videos on spray booths, large and small. If you do a search on e-Bay for ‘Portable Spray Booth’ or ‘Portable Air Brush booth’ you will see similar fold away spray booths as Ken mentioned and linked to. Less cost but you have to watch the shipping costs.

 

First thing to understand is … will you be spraying indoors or outdoors.

Indoor spraying needs:

- Over spray protection for the surrounding area – hence the need for a suction fan and an enclosure with a top and two sides.
- Fume removal – hence the need for an exhaust system to move the fumes outside.

- Explosion proof fan.

- Replaceable filter in front of the fan to catch the larger particles.


Outdoor spraying needs:

                Exactly the same needs as above but with more concerns of block the wind.

 

Let us focus on the fan – brushless would be the best, but higher cost. Don’t pick up an old fan where sparks are visible when turned on as the brushes make contact with the copper contacts of the armature. Aerosol can spraying can be ignited.

Many do-it-yourself spray booths seem to like to use high CFM bathroom fans with no problems.

I have not tried this or built a spray booth yet and really have not heard of any explosions when using them, not to say that it does not happen.

I do plan on making a spray booth and doing some air-brushing in the house in the distant future allowing me to spray during the winter months.

 

You mentioned a concern of clogging the fan … that’s why you need a replaceable filter to catch the larger particles.

Making a dog house – not sure if having a peaked roof is a good idea, fumes would be trapped there.

But maybe putting the exhaust fan up there could be the answer.

 

Hope of this helps.

Myself, I would be really interested to see and so would our members/guests to see what you come up with.

Hopefully some of our members will post photos and how-to’s on their spray booths, those that have one.

   I think that the ones that are used for painting models and trains like Kenny said can be modeled after the one on http://www.micromark.com and these should not be to hard to figure out seeing how we are all into building these models on toymaker the spray booth should be a breeze. For a filter maybe a furnace filter cut to fit the size of the opening to the fan duct then out side.

my paint booth once in life was a refrigerator, I use the freezer compartment for storage (wire hangers, hooks and misc. just gotta have on hand stuff, everything but paint). I mounted hooks from the top and put small shelf with lazy Susan and a piece of peg board on the sides to hang multiple projects at one spray session. small squirrel cage fan (vents out back top) and a ac filter (for intake air in lower front door). cut a hole in bottom of door and inserted ac filter. works pretty well, I just spray all parts and close the door and go get a sandwich and tea and wait (nothing worse than watching pain dry). I was going to re purpose an old large window air conditioner case to make a paint booth when I happened onto this on it's way to the scrap yard, since the previous owner gutted the compressor and copper all I was getting was a cabinet with doors (they wasn't dented an banged up either) wasn't bad deal (free) just to carry it home. when fnished my paint booth was $22.69 total

GCW - Well my friend, that was an interesting post on how to repurpose a fridge. I guess you could easily put in a rotating turntable and you are good to go.
