[AT] Air Lines

[Indiana Robinson]

	So far I have not found any problem just using rubber air hose. Its cheap, its easy to 
work with and if it ever fails there is no shrapnel. It is available in different sizes 
so you can start larger and step down but in my shop I have not found that to be needed 
for normal function. I do have the tire changer in about the middle of the line and it 
has an onboard air tank for the bead-seater. I think that tank helps keep pressure up 
during burst of heavy air use elsewhere. If you want to add a line just reach for a sharp 
pocket knife. If you want to turn a corner just turn the corner... you don't have to 
"plumb" a corner. Some might think it will freeze water in the low spots and I guess it 
could but I hang my working air hose in big coils over a hose hanger and if it were to 
freeze anywhere it would be there. Not really a problem.
	I had considered the higher pressure black poly pipe but I had the extra air hose from 
the tire shop days. I do want to put in a couple of kind of long underground air lines 
and expect to use the black poly for that. I am unconcerned about having high pressures 
or huge volumes of air in those lines so pressure drop is not really a serious 
consideration.
	BTW, I bought a larger snap coupler not long back which gives better air flow to stuff 
like my big blowgun and air tools. There are two things I don't like about them. One is 
that before I could work them with one hand, now everything takes two hands and sometimes 
a good bit of effort. Number two is that the old smaller coupler I was using was one of 
those that would accept several different kinds of male ends, the new big one only works 
on the one kind. I had a batch of oddball couplers from tire shops and was using some of 
them on air tools.
