Get off my lawn, punk!
I have a big barn turned shop. I put in two air reels on each end and plumbed a dedicated drop to my plasma machine just to save having to hook/unhook it. Built a small shed outside the barn for the compressor to keep the noise down. Plumbing? I looked at copper, black pipe, fancy shop kits and a bunch of different stuff. In the end I bought a 100' coil of good quality 1/2 inch air hose (~$60) and a few brass fittings. Maybe not the "best" way to do it, but I had it all plumbed in a couple hours and it was way cheaper. Someone go ahead and tell me how I am going to blow myself up and die. I am an infrequent user and don't keep it pressurized. Compressor is on a 8 hour timer switch that I turn it on when I need air and it turns off automatically. My compressor pump is old enough it will leak down to nothing in about 4 hours. Works great for me.
