DIY Mobile Spray BoothCompiled by ZuluHutu
Here is something some people may be interested in. I just build a mobile spray booth.
The reason for this: My big spray booth is 4 floors away.... but i really like to work with my airbrush As you know it is a little bit messy and smelly, so a booth is a must. So I decided to make my own small, mobile spray booth, so that i an use my airbrush in my apartment.
And before I did something really fancy, I also decided that everybody with a little wood working skills should be able to replicate this. For the greater good^^
I had the wood sawed to the right sizes at my local hardware store (i really don't know what the situation is in other countries, but in germany every hardware store has a cutting service).
After this you only some basic tools.
So here are some facts: (everything is metric)
The size is 40 x 30m x 11m and it has a foldable screen. The basic design is a big box with a smaller box inside. In the space between this boxes the screen is insert. The screen is made of thick cardboard, hold together by duct tape. Cheap and replaceable.
The ventilation is done by 2 120mm 230V fans, both together have a nominal power of ~400m³/h. Filters are a layer of polyester sheets (for paint), 2 layers of non-woven polyester mat (for paint particles and fumes), one sheet of activated charcoal (for organic solvents)....avaible as kitchen supplies (for the fume hood).
The air outlet is 80mm, so standard air pipes can be fitted to the box if it should really be smelly.Part List. Price: (48€)

just noticed my scanner is broken...i have to scan the drawing tomorrow at work....edit: I going to upload the plans as drawing.
General advice: You have to predrill and counterbore MDF before screwing the parts together. I used a 2 or 2,5mm drill and 3 x 30 (3mm thick, 30mm long) screws. I also used wood glue to strengthen the connection.
Cut a 80mm hole in one Part C.
Cut two 120mm hole in Part M.
Step 1: Build outer box.
Step 2: Add inner box. I recommend to put some small pieces of wood (5-6mm) between the two boxes.
Step 3: Screw together the filter recess, fix the fans to M. Pay attention to mount the fans in the right direction. There is always a small arrow printed in the fan casing.
Step 4: Before fixing the filter box, cut two hole for your power plug and the on-off switch. Wire the fans to switch, don't forget to ground the everything (use 3 conductor wire). Insulate everything properly using either heat shrink tubing or self-sealing tape. Test if the fans are running before putting everything together. WARNING
: Don't play around with electricty if you don't know what you are doing. But if you try anyways and get yourself roasted you probably done humankind a favor.
Step 5: Cut the screening.Pictures
