Now I still have to wire up to the air solenoid and clean up the hoses but I've been putting off mounting the nozzle assembly for about a year. All because the hose was too short. So this week I came up with a solution. Hose for fluid reaches. There was no excuse to not mount the mister.

So I found a corroded piece of aluminum flat bar 1.5" across. Cleaned it up. Used lots of the tools in the shop to center the holes etc. Drilled and threaded the aluminum casting to mount the plate. Drilled and tapped the plate for the valve assembly.

All done. Now even if I don't add coolant I can have just air blowing on what I cut.

So simple. Project 42 is done. Only 42 more to go.

Nice work.
Where do you get the hose fittings the blue hose fits into?
 
I got my air air hose & NPT fittings off Amazon. They were reasonably priced & decent quality.

Very nice add on to the mill.
I have been thinking of installing one but know nothing about them. I have never used or seen in use a mist coolant system. Does the mist more or less stay localized to work area? do you use a water soluble coolant?

I have used the Princess Auto push on fitting to set up air line drops in my shop. They work well providing the inserted air line have no side stress on the fitting or they will leak like a sieve. The Princess Auto tubing was so stiff and coiled curved, I had to strain relief it at every connection drops. My system is now leak free.
 
Truck supply business's are excellent places to acquire brass air fittings, trucks use them by the bushel. if you discover threads dont mesh from one brass fitting to another you probably have one air fitting and one with gas fitting threads, they are different and BBQ or Propane supply stores are your huckleberry in this case.

Mine was from KMS. Yes. I do have to switch off the ball valve at night or the compressor cycles every few hours. I've not figured out where the minute leak is. But then I have a fair number of places where I can connect.

The down side of mist coolant, as I'm sure many will state, is that it's like a spray gun and there will likely be atomized particles in the air. Not healthy I'm sure. The mill came with flood coolant which I've never used because the cutters will tend to wing it all over the place. Until I build shrouds around it like a Tormach or HAAS I can't see using flood.

This is what I bought from KMS Tools. The photo is from August 2022 so that's when I mounted the board to the stud wall. But nothing has happened since. The board is only there because it also provides the regulated and oiled air for the butterfly wrench pneumatic draw bar and cylinder.

A suggestion - get some 6mm-ish soft vinyl tubing. Just the right size to fit inside the locline fittings (stretch it to reduce the o.d., pull into each link and then snap the links together). No leaks when you twist the locline at odd angles.
 
When mine fails I'll consider that. At the moment it has 2mm tubing inside and the nozzle has the venturi to pull liquid.
However I help that along by pressurized air into the liquid container. So I can control both air velocity and fluid content
