I'd personally opt for an S10 gasmask and full NBC suit (MP5 optional)

Who wants to get rid the fumes?.......i love em......wifey wonders why i like spray painting so much, and the biscuit barrel is always empty....stoned as a hippy in a poppy field!!!!

Right folks here ya go
easy peasy
Go to boot sale or even down to homebase purchase a cooker extractor hood (mine was a homebase cheapo) then insert it above your moddelling bench and connect up the power !!! heres the good part Buy 2 charcoal impregnated filters and cut to shape !! place in the hood and switch.on The bonus of a light is brilliant also as it helps to see your work !! try the settings i find normal thined paint gets cleared at 2/3 and well thinned at full power !! dont worry about flamables as the charcoal holds the droplets in suspension. If you want it to extract out side buy the vent kit and drill a hole or get some tube and hang it out the window !! Mine works super fine without. Any questions please ask!!!!!!!

Would something like this be up to the job?

BAUMATIC STAINLESS STEEL Hood

http://cgi.ebay.co.uk/ws/eBayISAPI.d...MakeTrack=true

600mm Slider contol operation.

• 3 Speeds
• Extraction Capacity 290m³/hr
• Available in 3 Finishes
• 2 Lights

Screfix do them in a painted finish for £59.00 inc VAT that place on ebay is doing the stainless version for £49.00 inc delivery - seems like a good deal.

That will do just fine

I was thinking it might be nice to make a fold up spraybooth that folds down into a bench top. It could sit ontop of the bench with a small edging to centralise it, the top would then lift with a piano hinge along the back edge and then the sides would fold up, with some kind of catch to latch them together. I didn't want to construct something which will take a lot of place to store the thing and sit gathering dust and looking unpleasant when it's not in use.

A lot of Graphic Artists use a spray filter that sits ontop of the bench and then has a clear perspex shield over the top. I was wondering how effective a rear extractor would be against a top mounted extractor? I would have thought it would be nearer the source of the paint particles and fumes etc.

Also If the extractor was mounted at a lower level to the back of the booth it could sit on the bench, requiring a much lighter structure to construct the booth. I was thinking along the lines of 3mm MDF, Birch Ply or Even Corriflute. I thought corriflute sheet would be a nice material as it's very light, cheap, and it's also semi translucent so would give a small amount of diffused light too.

This was the kind of thing I was thinking of (see pic below) with the cooker hood rigged up to the rear of the encluse on a kind of stand. The actual booth would be light weight as it wouldn't support the weight of the hood.

most of the ready-made spray booths have the extractor below them and a series of filters to make up the base. 9 times out of 10 the object you will be spraying will be on the base of the hood so you will be spraying down, so this sucks it straight away!

Volume of air shifted is the most important thing and a decent cooker hood is superb

new to trains

we have a portable / fume cupboard here at work for use with solvents and Neat MEK, it is for the purposes of illustration like the spraybooth in post #16, but abit bigger,
it can also be used for spraying as well as solvent/ adhesives, we had it made by a local sheet metal company ( easy when the firm is paying i know- but not hugely expensive) but as MEK fumes are dense they fall, so at the back of this booth the tubing ( like a tumble dryer tube has a Y in it so it sucks from both the rear top panel but also from the base) really useful, but also advantageous as if you are about to spray paints, a minute of the fan running removes any dust build up since the last use on the base...... so prior to placing the item to be sprayed you can reduce any potential dust problems -so no or little dust in your fresh paint !
so if you are about to make your own spraybooth, with cooker hoods and tubing then consider having a lower and upper extraction point, its very useful, also by adjusting the fan speed you can also gain a type of electrostatic effect where you can actually suck paint into difficult to reach areas due to the base extraction airflow- the air movement carries the paint to lower surfaces...... this is not always desirable- it depends on the task ahead..... so the abilitiy to switch off this lower airflow is essential- on our system you just put the blanking cover on the Y output, its basically only drainpipe, but its a useful facility to have !

the motor/ fan we have is a plymo vent , basically just a big fan, the fabrication cost was under £300- its fairly lightweight sheet and plastic tubing but it works well and complies with C.O.S.H.H regulations which is a bonus !

I was thinking of designing the booth for easy storage as space is at a premium. The idea was that it sits on the benchtop and the top would latch on to the sides. Upon releasing the catches the sides could then be folded inwards and the back and top would then fold in half and be lowered down to fold flat making a reasoanbly easy to store flat box 50mm high or so. Obviously the cookerhood would have to be a seperate assembly or I might just go for some kind of fan and carbon filters. Hasn't taken a look at cookerhoods to see how easy fitting will be yet.
