A lot easier to buy a working coolant system on ebay. You can also
look into buying a misting cooler.

Like this? http://tinyurl.com/5dlmzc

Looks nice, and I like the pneumatic for pressure. Would make it a
lot easier to get the pressure and volume you want, but it does
nothing for recovery. In fact by using a pressurized tank you would
have to do recovery as totally separate and non-automated process. I
probably won't buy one, but I may make one now that I have seen that.
Maybe set up a recovery reservoir with a float switch that does an
auto shutdown when my recovery reservoir gets to about 1/2 the
capacity of the oiler. Then I'ld never run out of oil if I walked in
the office to get a soda and got distracted.
Mister? I guess you could do it with a venturi style pickup instead
of a pressurize tank, and then just play with your pickup and nozzle
size to get a nice spray.

I did some research , ended up designing and building a mister that uses a
pressurized supply . You CAN inject the used coolant back into the tank ,
just use a small orifice . Check out water injectors for steam boilers ,
some use a similar device .
The reason for pressurizing the supply is to help reduce water/coolant
vapor in the air . The air supply is at a lower pressure , therefore the
mist is of a "coarser" consistency . Larger "droplets" mean less
evapotation , and less moisture in the air .
The last thing I want around my machine tools is a moist environment .
