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.
www.wmcpumps.com as on the back of the pump. I chose a 3mm tube but if I replace it will use a 1.5 mill

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.

Since there is no requirement for a venturi or pressurized container almost anything works, I just used an old NOGA that I had.
I made it for myself, I have no commercial intentions whatsoever. I am 80yrs old and in the middle of a delayed midlife crisis.

Just a note about my vision of the correct flow shape. I would like to illustrate how i like it. See photo below.
I maxed the cooling supply so its more clear whats happening. When milling aluminum you can barely see the coolant flow. When nozzle properly made /IMO/ the overall "flame" shape is long and concentrated and in the middle forms a very nice thicker stream, it basically sounds like a nice small propane turbo burner . No mist at all. You hit a wall with this stream and it all goes down, nothing up in the air.
that stream bellow is should be enough even for engraving stone and soon i will try it when i have my machine ready :-)

Have just ordered something from Amazon for £15! Basically its the venturi, 2 flow control valves (air and coolant), a length of Loc-Line and a nozzle at end. Not sure whats going to happen but sure we'll see.
Question; What is the fluid used/ Soluble oil and water or what? WHAt dilution / ensity should the fluid be?
For the price I'm not expecting any instructions
Will
