So I finally got around to making the mist system for my mill. I’ve a couple questions what kind of psi are y’all running 10 psi seemed pretty good to me I was getting more of a splatter than a mist. I watched some of the fog buster videos and that’s what they looked like anything over 10-15 psi seemed pretty foggy. Also what are y’all running in your systems Koolmist 77 seems pretty popular. Let me know what you think.

I have the regulator set at 20psi. Then open the air valve enough for chip removal then open the coolant valve just till the temp drops in the air flow. 20 min. on the mill today I used less than 1/2 teaspoon coolant.
 
I have (had) a Kool Mist. Hated the adjustments. Seemed like I was always tweaking it. It never started with the same flows. I got one of the cheap, "two-valves on the body" ones on eBay. Absolutely love it. Bob is right, you want small beads of coolant, not a fine mist. There a lot of these out there. This is the one I got:

They are easy to adjust the air and coolant independently. Especially while the CNC mill is cutting. The "nozzle" flow adjustment on the Kool Mist is too close to the turning cutter to adjust in real time.

Only problem I had was the Loc-Line kept snapping off at the body if I bent it just a little too far. I had the same problem with the Kool Mist one too. Found a Loc-Line clamp solution that has never failed to hold:
