[TheForge] pneumatic tools and pneumatic tool oil

[terry l. ridder]

hello

while working on the truck with the impact tool, a question popped into
my mind. Whu does not the oil in an pneumatic tool, "diesel", i.e.
combust. there is compression and there is oil. I use mineral oil so I
am not entirely sure what conditions would have to be for mineral oil to
"diesel". I would not want to try diesel fuel or keresine.

The next question that popped into my mind, when the exhaust from the
pneumatic impact tool was becoming ice cold. what is the possibility of
ice forming inside the pneumatic tool? I would assume extremely low.

could the chilling effect on the air exhaust causes me to think that a
simple device could be made that would produce a cold air exhaust to be
used to cool drill bitx and lathe bits. the old PVT relationship.
Pressure volume temperature.

turns out French physicist Georges Ranque discovered the vortex tube in
1930.interesting device. why is it not in use today?
