Water Atomisers - Any idea's please? Answered

Hi, thanks for stopping by! I need to make about 250 atomisers (not sprinklers) for water for a planned project. I bought some Hozelock misters - which were not cheap - which did not deliver the promised misting action - they were simply poor unadjustable sprinklers. I had thought of getting some hard plastic white plumbing pipe and drilling a 30 degree conical bit into it so that a hole about 0.5mm is made and that the 30 degree cone shape would help direct the spray. Do you think this would work- and should the hole be made smaller perhaps? I use the word atomiser carefully - I'm not bothered about an exact water droplet size but I definately don't want it so big as to be a sprinkler. Have you any thoughts please? Thanks again for looking in. Kevin


If you increase the pressure into the misters you have, that may make the spray mistier. Otherwise, consider directing fine needle-jets onto flat surfaces to get a mist from the spray.

Thanks, Kiteman! Any ideas' on how I can achieve needle-sized holes? Cheers Kevin

Not sure if Dremel* tools go that small, but that's where I'd start looking. Or maybe among jewelers' or dentists' tools (you might be able to get a price break on these used)?

(*I sure that's what they're called in the UK :)

Hi Gorfram! You've been busy today! I am so ham-fisted any drill bit below 2mm gets broken! Your comment was useful though, because it made me think of using a pillar drill with a countersink bit and to drill the pipe directly until the bit just about breaks the inside surface of he pipe thereby creating the tiny hole with a nice flute to spread the water mist. I think I'llgive that a go, my overriding worry is putting too much pressure on the water pump by making it force water out at a higher pressure than it can stand. I did speak to a hydro store and they acknowledged the problem saying pumps rarely last beyond 6months. So thnaks for that - I truly wouldn't have thought of that but for your post!

If you can get the precise measurement - and jig the work so that it's the same maeasurement everytime - you could put a mechanical stop on your pillar drill so that it will only descend to just exactly the right depth. My dad use to use a chink of wood cut to length and clamped in placee to butt against and stop the drill's (sole plate? platen? thing the chuck sticks out from?), but you can probably find (and would need) something a little more high-tech and precise than that.

(FWIW, the asterisked sentence in the previous post was *meant* to read:
"I sure hope that's what they're called in the UK.")

Yes, I guessed the FWIW sentence! Thanks! Yes, by trial and error on a scrap piece of pipe I can achieve the exact depth - thanks!

lol! of course! (not accurate enough and I don't fancy burnt fingers! but thanks anyway!)

I wonder if securing a 0.5 mm or smaller mesh over the spray nozzles of the unsatisfactory Hozelocks or over holes in the plastic plumbing pipe would work? Not sure how best to do the securing - superglue? solder? hose clamps?

Perhaps you could use aerosol (e.g. deodorant) nozzles? I've got a few which I've separated in the recycling process - I guess they'd hot-glue in place? L

Thank you for your very kind replies, Lemonie, Tool & Kiteman - I will certainly give your comments a go! I'm not sure where to go with goodhart's kind words but I appreciate his time to spare his thoughts. I will report here again when I have come to a decision so that others reading this can have some conclusion. Any more thoughts, anyone? Thanks for stopping by!

there are mister / atomizers made, normally in a small package (not sure what you are using it for), like the one I got to mist our Budgies. The mist is not adjustable, but it is really a fine mist. If you mean a motor driven one, they make them for those with asthma or sinus problems (but hot and cold misting machines).
