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

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.

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 :-)
