I tried a veggie coolant once. They claimed the coolant and way lube were
the same so the way lube would become coolant. Amazing concept. Horrible
result.we cleaned the machine and coolant tank with soap and bleach, put
the mix in on a Saturday. Monday morning you could hardly walk in the

because they donate it to us. No smell, no growth,

THE best coolant to cut aluminum is WD-40. Bar none. I have never misted it
but I used aerosol cans of it. Never a problem with a cloud of mist.
The best flood coolant has been Hangsterfer's. Never an odor problem. Never
a problem with separation while sitting unused.
Just sayin

I do
In the toolroom where I work, we used to have Li'l Mister non pressurized
reservoir misters. They caused a cloud in the room unpleasant to breath.
We now use Fog Buster that uses a small amount of pressure in the feed
bottle and it's much better for the surrounding air and much better to
control.
Why not flood with neat cutting oil? It's a much nicer smell, although
you do need to watch out for staining of close-fitting surfaces.
I have serious doubts about the health hazard that a mist of any sort
poses to the operator's respiratory system.

For steel oil mist, see here for ideas:

For aluminium some sort of alcohol, see datron...

Thanks Mathew.
The stuff I was looking at is Kool Mist from KBC Tools.

For the band saw I have Powerfist cutting oil marked for mixing 5:1 to 100:1.

Oh yes. I just mentioned the math courses. Not the computer ones. Most of
the first year computer stuff was all done in APL. Not exactly a database or
text processing language so you can see how learning about random numbers and
some of the other stuff can have labs attached.

What happens is these concepts get beaten into your brain so well that we
think we never learned them and it is just "common sense". Not no it is
not common sense, the smartest people who ever lived spent much of their
life figuring out something in the mid 1600's and you learned it in 10
minutes
I'll bet that on top of the calculus and linear algebra they also covered
discrete mathematics and some of the nifty things Allen Turning and John
Von Neuman discovered about if machines will halt or not and the
relationship between sets of grammars and sets of machines and you proved
