I think this is cool=) öhm... course its cools as it cools it down, what i want to say its a neat thing=)

If you are machining, start using protective eyewear now! I used to cut aluminium with my protective eyeglasses on and even with the use of glasses I had to dig scrap-aluminium out of my eyes couple of times. Its not nice to have 1cm aluminium stick prodtruding in your eye and trying to keep eyelash open with your your hands as to get no more damage and trying to get it out in front of mirror with pliers.

Use he protective eyewear! I think it still saved my eye, without them it could have been way worse

We need more oil/water cooled setup manufacturers, this is cool!
