    The tube is just for transporting the already mixed air and coolant, the valve directly above is for metering the coolant.

    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.

    Amazon.com: 10" Standard Filter Housing, Clear/Black, 1/4" in/out: Kitchen & Dining

    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.

    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

    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?

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

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