I don't need mist for most stuff, so don't want to spend a lot on it, but it would be nice to have. I have a CNC router with a high speed spindle which holds endmills up to 6mm.
So far I have only tested it with water. It won't siphon up the water at all unless I run the air at very high pressure. If I lift the reservoir above the nozzle then the water flows too freely, even with the air off. I've used mist coolant in the past. The unit I had years ago worked well enough that I never had to fuss with it, and so never learned anything about how it worked. The only thing I can think of now is to keep the reservoir high, but somehow restrict the flow. Any tips, or should I just toss the thing?
Thanks,

Sorry to keep posting, but here I have found what looks like an excellent drip system that would be cheap and easy to make:
