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.Quote:

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,

So best to look at fog buster or similar? I built my own but limited success with it.Quote:

PS. If you do it properly similar to mine, it DOES NOT mist. It spits small droplets, not mist. Thats why its called Foggless
Thanks, can you link the one you use please? I recall you made your own?Quote:

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?
If you have to use an alcohol then Isopropanol is cheaper, http://www.newshinyhardware.co.uk/Ch...nol/1000ml.nav and is not loaded with purple dye, bitrex and pyridine like meths. I would avoid a flammable liquid which is dangerous to inhale if possible.
More to the point, why are we resurrecting a year old thread?
Holy Thread Resurrection Batman! :DQuote:

Agreed, Im currently using ethanol used fireplaces. It has minimal smell but of course still very flammable. Mixing it with water might be an idea.Quote:

And as my transparent container was a good quality one/ the water filter/ there is no problem with the plastic from the kerosene.
For those using alcohol for cooling, does it also have any effect on aluminium sticking to cutters or is it purely for cooling?
kerosene (28 Sec) is readily available all year long if you ring a fuel supplier I used to run my steam cleaning machine on it it's was cheaper than red.Quote:

I personally wouldn't use kerosene/heating oil, solely due to the smell, however I suspect what Boyan is suggesting is the paraffin you can get over here for camping stoves, which doesn't have as strong a smell.
But there is a reason it's called " fogless mist cooler" . If it makes a fog in the workshop and smells, its because the nozzle is not spraying drops and usually is overspraying. i said it many times, 0.6-0.7mm is the ideal nozzle size and can refrigerate a bit up to say 20mm . For 1inch and bigger cutters, 2 nozzles.
Normally i will put a lamp at the back and check if its not making fog before i leave the machine to cut.
Reopening this old thread to share an observation about using ethanol as a cutting fluid for aluminum which may help others avoid problems.
We reported on a machinist who tried this in a poorly ventilated room.
We do not recommend this.
See our paper titled “Neurological effects of chronic occupational exposure to alcohol mists and vapors in a machinist”.
