I used a MIG nozzle as per link in Post #17.

I just built one of these using a very cheap water filter canister. The clear ones at lowes were around $40.00, I found one that works perfectly on Amazon for $8.80. It uses standard 1/4" NPT connections and made for a super easy build.

Perfect timing Jim! Was just about to go and spend $30 at the local hardware store. The Amazon one looked great UNTIL I found out they won't ship to Canada. Found the same filter at AMI for the same price but they want $32 just to ship it.

Thanks anyway!

Hi Jim,

I am thinking of building one of these fogbusters and would like to know where to get the plans for the one you built. Are they available?

Thanks,

Hi Marty, the thread title is "How I built a fog-less coolant mister", so I'd suggest reading this thread.

Hi Guys

What are you Guys using in your DIY Fog Blasters (FB)? Anyone using a Flood Coolant Mix? I would think it should work fine. When I get around to building my FB, I want to be able to use the same Nozzle for booth Coolant/Air and Air. I think you can do this by adding a couple Valves. One Nozzle makes for a simpler setup plus you only require one mounting system for the Nozzle.

For those of you that are using the water filter canisters. How do you run the tubing into the bottom of the tank?

[dogmeatk]

Willy, I Have been using Slugger cutting fluid. Mostly because it's the only water soluble cutting lubricant I could find locally.

As for coolant/air and air only, this design already allows for that without adding any more valves. You just close the needle valve for the coolant mixture all the way and then poof, air only

[ex-egll]

Hi, Finally got around to completing the project today. All went well until I opened up the coolant valve. No coolant! There was plenty of odd sounds and bubbling but no coolant. The problem was solved by putting a second needle valve into the system. This valve went between the solenoid valve and the mixer block. All I can think of is that the water needed more air pressure than the air stream to force it through the system. Anyone else come across this?

[Fastest1]

Mine is manual but I installed valves as you have drawn. It gives you more control of the mixture at all pressures.

[ex-egll]

Thanks, glad I hadn't done anything too wrong. Put the second valve in and the FB works as advertised!

Well i used to tremble, the pet container until it was rock hard. I have no concept, what the pressure was
but it was certainly much greater than the pressure in the mister program.

I was informed the link died on this very old thread. Here's a current one:

FWIW, the original is still in use. I'm sure well over 100 folks have built their own.

Very interesting thread, I will keep following this for further information.

Used Forklifts

[Karl_T]

Kind of forgot about this thread.

After only 12 years, I retired the original. One weakness on the original was not being able to use air blast only, nozzle too small. Also couldn't point it right at the cutter for a deep slot.

This version uses Lock line, smallest size. Not quite as good at making small mist droplets without fog, but acceptable. This is due to the far larger nozzle - 0.0625. But this allows air blast only by turning off the meter valve and turning the air pressure up.

Also simplified construction by doing it all on the lathe and tapping 1/8 NPT for the Lock line.

Hi all......just to add another two pennoth worth, I see the system uses air to do a mixing process and you meter the air coolant mix accordingly to give a very wet mixture that comes our as droplets rather than finer mist.

Now having an air compressor on all the time is inconvenient as it cycle on and off etc even if it does use very little air.

I have a back pack pump sprayer for weed killer and other things and this pumps up and dispenses the weed killer as a fine mist or coarser if you want it to do a quick soak, so it could be used for the system but as it needs to be hand cranked to get pressure it probably is an air.fluid mixer which is inconvenient.

I also have a hand spray bottle with a trigger pump that sucks the liquid up and according to the nozzle adjustment gives out a fine mist or a water pistol like jet.

If this works by pressurising the liquid with a plunger and forcing it through a nozzle to atomise, then all it takes is a sealed pressurised container with the coolant and a static air supply......without consuming yards of air.

What I'm talking about is a mist coolant only without the air blast, but I have the feeling that it is the air blast with the coolant that atomises the liquid and drops the mist temperature and so cools and lubes the cutter, as opposed to just a stream of droplets to do the cooling.

If the stream of droplets is sufficient to do the cutter cooling, why use air?

Does the air/coolant mix have to be used as a chip clearer too, which would not occur with a flood coolant system that relies on just the flow of the coolant to do the cooling.

I get the impression that the airstream is the main component and the coolant, which is sparingly used, becomes the add on part for the lubing of the cutter.

I don't know what pressure the hand held spray bottle gets up to, but if you look at a scent sprayer with it's small rubber bulb, there is not much there when the mix is atomised.

I might be overcomplicating a simple plan, but I want to get away from any form of compressor in the design and so a small pressure pump comes to mind..... something that will give about 10 PSI which is more than I would get with a finger rapidly pressing the trigger of a spray bottle.....as long as air is not the main component required to cool and atomise.

handlewanker. Just thinking along the lines you are but what about an aquarium air pump? Not sure of the pressure they put out but something along those lines could replace the compressor side of things....

[handlewanker]

Hi, I don't think an aquarium pump has enough pressure to move the coolant as the pressure is derived from rubber diaphragms electrically activated.

Hi, just been genning up on spray technology and what it takes to atomise liquid into droplets.

If you pump the liquid at pressure through a small nozzle it will atomise into droplets......I think this is how a plastic spray bottle works, in which case there is not much pressure required to make the liquid spray.

However, for the purpose of cutter cooling and lubricating, it may also require an air blast which in itself will atomise the liquid and form a spray of droplets.
