    My spray booth - As it seems to have vanished I will put it here.

    So winter was on its way. no real heating in the shed/cave and no electricity unless the weather was dry (extension lead to and from house), so it looked like a case of rattle can primer, then once dry spray with primer or build and then wait for warmer weather to paint.
    But trawling through YT one night I came across this video -

    And I thought yeah! ok another weird idea to gas yourself....
    But then I thought about it and reason set in so I ordered the items required including a new spray booth and table (which seconds as a bench extension)....

    And here they are minus the table which was still folded away...
    So the first job was to open up the foam which comes shrink wrapped and its main use is for acting as a fileter in a fish tank. This once carefully unfolded was placed in a bucket of water to expand to its original size 2ft x 2ft, then allowed to dry (3 days + 1 in the airing cupboard)...
    During this time I assembled the bucket/water trap. A hole 10.5 cm diameter was cut into the lid, with 8 half inch holes drilled around the top to allow air to escape, and once cleaned up the extraction hose was stretched out about 12 inches and fed through the hole. Once satisfied with the length inside the bucket (8in) I used mastic sealant on both sides of the hole to seal in the pipe and allowed it to dry for 48 hours once smoothed and cleaned up.
    I then got out the table and unfolded the legs expecting a smallish size but it is about 18in x 36in and was ideal for the spray booth to fit on lengthways.
    The spray booth was assembled and tested to make sure it worked...
    Assembly day -
    The lid was placed on the bucket but I did find that the pipe had a tendancy to lift the lid - this was solve by a length of masking tape wound around both lid and bucket as you would a parcel (no water yet).
    The other end of the pipe was fitted to the rubber seal and instead of using the aligator clip to hold the seal onto the spray booth I used it to hold the seal onto the pipe and push fitted the seal onto the outlet on the back of the spray booth...

    The foam was cut in a 12in x 12in size and then a hole 10.5 cm was cut in the centre and the outside diameter cut to match the bucket lid and then a cut made from the centre to the outside to allow the foam to fit around the pipe. I did add some small squares of double sided carpet tape between the air holes just to hold down the foam....

    And there it is all assembled...
    I did a test run and sprayed some IPA into the booth and to be honest there was no smell except when I forgot and sprayed the rest into the waste paper bin :rolling:...

    And here it is fully working, water in the bucket (about 3 inches and scented with some 'pine' floor cleaner) - Does it work - yes, and I stand humbled for doubting the guy who put up the video....
    Cost - For everything just under £100... Time for construction - however long you want to take

    Now that really is a quirky solution. Glad it works. Quite a simple idea though. I wonder how long before it will need a clean to maintain efficiency.

      Just a change of water and the filter material , I'd do it depending on use, but would the water develop a smell with age ?

        Great idea. When you think about it, what you have there is a large colour change pot……like this only bigger….

          Personally I’d put just a capful of bleach in the water when I refilled it. Should stay bug free then. Mind you, if you spill the mild bleach water on a carpet you won’t stay bruise free……the household authorities will take a very dim view of proceedings.

              Nice idea Mike. When I first got an AB I was too far from the Window and so used to 'vent' into a bucket of water too - albeit without the foam but I only use water based paints, so the smell is less of an issue.

                Hello Jim,
                I am working on a policy of once I have finished spraying then I would empty the bucket untill the next time. How long does it take to put the water in..

                  No, this is what you use when you have finished spraying and want to get rid of the excess paint and clean the airbrush... Got one totally useless, SWMBO now uses it in her greenhouse.

                    I use Zoflora so if there is a spill it will not stain the carpet, and basically what has not been spilled on a modellers carpet.

                        You were nearly there, and in reality this was mainly for lacquers and enamels, but nothing stopping you from blowing into the bucket.

                          Interesting…..mine works well as designed, though I do put it in the spray booth. No idea how you’d use it in a green house though?

                          The bucket idea still works in exactly the same way, and is a clever use of the same idea. Air/paint mix is pushed into the container by the spray booth fan. Particulates in the exhaust stream are captured in the filter, and solvents are captured by the water. It may be more effective because the air flow into the bucket has a lower velocity compared to the airbrush nozzle, and velocity is dropped even further by the change in diameter from tube to bucket, but the principle is identical.

                            What a brilliant idea. Just been using a rattle can primer, but had go in the garage. Soooo need a spray booth. Saw a YT this am using a plastic box and bathroom fan. This setup would allow me to use the end of my build table for spraying. I can feel an amazon delivery winging it's way to me already.

                              That is what I made up for my airbrushing Andy, except mine was a real cheapo, cardboard box with an old bathroom extract fan and the silver concertina hose that was with it stuck out of the window, and to be fair it does a fine job.
                              Strength isn't about what you can do, rather it's about overcoming what you thought you couldn't do.
