Extraction, extraction and some more extraction ;-)
So in a home / garage environment, Ill need to build something for this? Not sure what the costs / technicalities are for this.
I could continue to do Flood on my Triac however my new machine will not have Flood, well, not planned for. I may reconsider this.
Cold air needs too much air, Ive looked at this before. I dont think its a DIY option.
So Id like to know what options we have for 100% dry cutting. Clearly its possible .....?
Even if cutting dry you will need to move chips and vacuum isn't even close to air for getting chips out of the way in holes and slots, so why not look at something like Boyan's solution to add a little lube to your air, then you can use a good bathroom extractor to keep the mist from filling the workshop,

With mist and fumes collector and filtration

PS. If you do it properly similar to mine, it DOES NOT mist. It spits small droplets, not mist. Thats why its called Foggless
On the subject of coolant, has anyone used this brand for aluminium?

I don't know why you are trying so hard to find pure ethanol.
Pure ethanol is subject to alcohol tax as it can be used to make alcoholic drinks.
To avoid this tax, the ethanol can be spiked with about 5% Methanol making it UNDRINKABLE. hence the term 'methylated spirit' or 'denatured ethanol'.
Methylated spirit smells almost identical to ethanol. Methylated spirit purchased in pharmacy or supermarket is further spiked with purple dye, bitrex and some horribly smelling crap that I forget the name of. Obviously to stop idiots drinking it.
You can easily buy methylated spirit without the stinky additives etc.
Small quantities vaporised with decent ventilation would be fine (healthwise), If you went crazy with it, you'd get high as a kite and or start a fire. I'd worry about electric motor in fume extraction equipment.
It may be possible to dilute the alcohol with water to decrease risks?
