I got fed up with trying to get the flows right, so made this

You could sell that at Etsy as steam punk art . Man, its beautiful. Looks like a mist cooler coming from the future or like something savaged from a spaceship station

Totally independent control of Fluid and air, air can be pulsed for better pocket clearance,without affecting the amount of fluid delivered. Can squirt fluid alone (up to 90 cc's a min )for some jobs.

Fluid container can be put wherever you like ( within reason) , does not siphon or drain back, will handle different viscosity's .

I Like the sound of that John and very well made. . . . Got couple of Q's if you don't mind answering. You may have just added another Job to my endless list.!

Whats on the heat sink on right.? Looks like thermister, resistors and black box which I'm not sure about.! And what are they doing.?
What and where's the power source.? ie voltage.
Where did you get the peristaltic pump.?

Not really a heat sink, just a packer. underneath is an SSR to control the air valve, the square with a red blob is a 12v lamp-flasher which gives me the pulses, next to it is a 12v reg. (with a couple of ceramic capacitors ) needed because I am supplying 24 volts from my main panel. The AUTO mode is an M7 relay in the panel.

Thanks John I got the Jist of what would be needed to make this work from pic and the Reg I recognised but it was the Blackbox with what looked like a Thermister above it that thru me off.! . . . . . Now I look again can see it's part of the black box.!

That with the pulsing seems a great idea. I missed that.

I didn't mention the round black item - this is just a small air reservoir mounted directly on the air valve, (bigger would be better but its what I had lying about) it gives a bit more bite to the pulses and dampens the air gauge a little.

That being said it still leaves the question of the nozzle/delivering tube/body /support/connectors assembly. How do you do that?

Another question is the complexity, some times simple things last longer in industrial enviroment , on the other hand it can be expensive for eventual time to time home use or on a small cheap machine.

I mean is one thing to design an usefull system. My Russian friend who is an experienced model maker did his system for under 5 minutes from what he had at hand.
Its another thing to design cheap, clever, reliable and nice looking product/in that order that could cover most of the real needs of fellow machinists.

You made that for yourself or with the idea of selling it?

And when you will need the squirting? from my experiments even tiny tube could give tremendous flow. In fact for comparison 1mm nozzle gives 160l/min flow if i remember correctly some plasma cutter torch specifications

I could make a crude system in 1min by just piercing tiny hole in bottle and letting gravity do the work dripping droplets in front of my air nozzle. It would have the same characteristics has Johns system in that it would be independant control of air and fluid but I wouldn't because it won't be affective and look shite.!! . . . . I don't get your point is what I'm trying to say.!

John's system is metered indepedant control of air and fluid which in practice will be be much more usable than any Fogger sytem. I would relate Fogger equivalent to normal hammer and based on my experience estimate Jonh's sytem to be equivalent to Piano tuners hammer.!! . . . . Both hammers but different.
