	Drill string is some tough stuff.  Probably a good choice.

	One other point, PVC is not a good choice for pressure line.  If it 
breaks, it will do so five minutes after you leave on Friday evening and 
your compressor will run until it self-destructs.  I know because it has 
happened to me.  Spend the money and plumb it correctly - you will not 
be sorry.

every now and then.
