Ok... I'm still mulling over the possibility of a Hilsch tube on one of my machines as the coolant and to blow chips
away from the cutter. I see many commercial ones are made out of stainless, but that just isn't in my plans if I make
one. Stainless is beyond my easy working level.

I'd consider a long coil of mini copper tubing inside
an ice - filled cooler before I'd consider a Hilsch tube.
