Cannot justify building a custom spray booth. Other options

[flanajb]

As you may have seen from my other posts I have been researching building a spray booth for my garage, but having concluded that it will cost in the region of £350 to build I just cannot justify it. I only make 2 -3 pieces each year as my hobby, so it is rather extravagant.

On the other hand I cannot bear to settle for second best when I make a piece and so it all gets rather annoying.

The roughness of the overspray is just too much to accept, but I have run out of options with how best to proceed. Even with the garage door open then amount of overspray I could see being emitted out towards the neighbors car was butt clenching to watch and I was dreading a knock on the door!

Anyone near Blandford who has a spray booth, please do get in touch as I would be more than willing to pay to hire it, just so I could finish my next piece. Have spray gun, will travel!


Thanks

I'm Romsey way if that helps?

Thanks Stu. Before I take you up on your kind offer I will wait to see whether there is anyone a little closer.

A collapsible , used occassionally, spray booth has been on my mind for a while....for myself. My thoughts so far are hinged side screens which can be set up, with butterfly screws, or ready made wood spacers...or something easy to lift and store away. A top to fit so giving further stability. Made of cardboard,( fire risk), insulation board, or something heavier...white hardboard. Then comes the fan...not sure if it needs to be fire rated (perhaps not if using water based paints, a flexibel hose connection to outside...tumble drier or fan venting kit type of thing. A good sucking fan must start sounding like a £100+ To outside would need a board with outlet hole postioned at base of door or window ( a bit like early tumble driers!) and some sort of baffle.....newspaper in wire mesh to collect and stop drift into best car outside. The floor of workshiop dampened down may be sufficient or a floor similar to roof panel Not thought any further but I am sure it is one way to go....paneling, 2x1 framing, hooks fro gun. Overall size to suit but say 4' x 3' x5' high for straters. Then comes quetsion of some heat being required...as doors will not be air tight....?

I am writing this to open up your question as a possible route to go as I am sure there are many out there who do something like this. I have never seen a commercial set-up so could be far of beam. Best wishes.

I have researched this in some detail and have concluded the following

1. Industrial extractor fan. 4000+ CFM : These start at £130, and 2nd hand ones are like rocking horse ****
2. You need the concertina filter paper : ~ £30
3. Ideally a mesh filter behind to capture the dust : ~ £7 for a 450mm*450mm one
4. Speed controller : ~ £30
5. Materials to build booth ~ £50

So as you can see it quickly gets expensive

Any links\suppliers for the fan?

Thanks for the sums. You've been there and tried it. Back to the drawing board. Another way....? Mm. Best wishes. Hope you get sorted out.

The only ones I have found are on ebay. Just do a search for industrial extractor fans. There are a couple of people who sell 450 or 500mm fans which when combined with a speed controller should do the trick.

I've spent years with this dilemma. I've built several Heath-Robinson affairs, including buying a gazebo-type tent, and have come to the conclusion that there is no good, cheap way to do it. Either do it properly or don't do it. It's not a palatable choice.

Although I do hope to have a spray booth in my next workshop, I am quite convinced that the best way for hobbyists like us to finish pieces is by hand. Modern hardwax ols give a really excellent finish, can be applied in a single day, don't smell very much and don't need extraction, just a clean warm area. I've used Osmo and Chestnut and both are excellent.

The downside of this is that you are limited by the range of finishes. Neither of the above is a high gloss, for example. But they are very attractive satin finishes that are pretty foolproof and ideal for home projects.

You can spray outside on a fine day, but the slightest bit of wind will mess things up. Until I get my proper spray booth, I'll be rubbing hardwax oil.

Trouble is Steve. Once you have dipped your toe into the spray finishing world, you don't want to leave

Idea 2 http://www.ehow.com/how-does_5025610_building-spray-booth.html

idea 3 [urlhttp://www.richardaerni.com/pdfs/How%20to%20Build%20a%20Glaze%20Spray%20Booth.pdf][/url]

idea 4 This is a bit of a follow my lead please....the journey might look a little complex but stay with it.
1) http://www.woodworkforums.com/f40/sturdees-finishing-shed-8964/

2) http://www.woodworkforums.com/f200/sturdee-filtered-air-blower-9308/

The last idea is to convert a shed ( maybe 2nd hand from ebay) and if using water based finishes then to use a big squirrel cage fan to extract with........maybe too expensive for your needs.

Ah yes, that I understand only too well.

..how about asking your local commercial kitchen canopy fabricator for any old kit...I imagine they'd work well & the these firms should be replacing old ones all the time. An old aluminium one would be cheap as there's no scrap value in it...perhaps offer to be there to help take it out -it'd be filthy dirty mind...just an idea...or check out catering auctions for 1.

My workshop is in an old print factory which has an old spray booth in a dark, dank corner.. it doesn't help it being in Brum.

Thanks for all the posts, but as Steve has highlighted, if you try and skimp I suspect you will end up with a sub standard booth.

Half the battle of bringing the cost down is getting your hands on a 2nd hand fan. The idea of contacting companies that specialise in kitchen extraction is a good one and I will do a bit of investigation into that.

Please do keep your comments coming as it is all good stuff. I will of course keep people posted with my progress

Got my hands on a woods explosion proof fan from a friend of mine who's company was closing down for £15!!

Only slight problem. Got home only to find out that my mate was a little confused. It's 3 phase ](*,)

Hi

Not sure if you've seen my spray booth build here: https://www.ukworkshop.co.uk/forums/spray-booth-build-t47869.html

I still use it now and I'm really pleased with it. I think if I were to improve it I would probably use a larger fan and try to filter the exhaust. Bear in mind I only use waterborne finishes (Morrells 362) so I've not used a special fan for the application.

If I can be of any help just pm or post.

Cheers

Richard

Hi Richard, thanks for the offer of assistance and the link to your booth. I think my only option is to just put my hand in my pocket and buy the parts needed for the booth. Like you say, you can do it for £250, but I was hoping to do it for less.

Thanks

That's a beauty !

& there might be a way to use it on single phase (by using a few capacitors) .. there was a post on it not so long ago.
The info was gleaned from a book or 2 at Axi about all things you need to know about motors. It must be worth a go at only £15 to lose.

.. there's a very knowledgeable gent on here who'll know more than most - Mr 9 fingers.
