Mist cooing systems

[Mark_1984]

I've just seen Stuart's latest video where is shows a KoolMist cooling system.
This seems like a good idea, better than my current practice of spraying WD40 or WD40 cutting cutting fluid from a can.

Does anybody have any experience with these and can offer any advice before I splash out? KoolMist don't seem to be easily available in the, but Chinese imitations are quite cheap. Are the cheap copies any good?

Thanks in advance.

I used water filter canisters and modified them
The Coolant nozzles I got from Aliexpress
There are two separate systems one for the lathe and on for the mill, there is a 12 volt solenoid in the air lines connected to a switch to turn them on or off
They only require about 5 to 7 pound pressure in the canister

Tom Lipton (Oxtoolco) posted a video to YouTube a while back on a system he built with a 2-litre bottle. He provides a good description of his system:



The mister portion of the video starts around 09:21.

He also references a similar project by James Kilroy, which I have not watched.

Technically, I think a mist system is the one that produces a fog of mist, with attendant concerns for respiration. What is described in the last video above is a Minimum Quantity Lubrication system (MQL). Here is what I worked up for an MQL a couple of years ago: https://www.homemodelenginemachinist.com/threads/mql-system-compare-to-fog-buster.34016/

I have to confess that I have not used it very much since, in part because it needs better valves - I used some very cheap-o valves that do not allow very precise control. It is in the long list of "one of these days ..."
