[AT] Air lines for shop

[Alan Riley]

I used copper when I ran air lines in my tractor shed about 20 years 
ago.  It was Type K or Type L, whichever is the higher pressure rated 
one.  I used 3/4" for the main run and 1/2" for the drops. I've never 
had any problems with it and would use it again if I ever did another 
installation.
