I just bought a 60 gallon compressor and was wondering wether to use just air hose or metal pipe to several connection points throughout the garage. What have you done with yours?

I have mine on a concrete pad just outside the garage. I snipped an inch off the mesh from the garage vent there, and ran the hose & power in through the hole. Prev owners had firewood on this pad, and it's the perfect size for my compressor.
Inside, I have a hook that I coil up a long hose on and the Vette is parked on that side of the garage. I just unhook a couple of loops of hose and walk around the car with it.
If I need to use air in the driveway, the hose is plenty long to reach out there too...I just unhook more loops of hose.
Copper pipe is very good but, EXPENSIVE, threaded pipe is OK but will rust inside, plastic pipe is commonly used but, is DANGEROUS! and has the potential to EXPLODE and sharp plastic pieces can IMPALE and possibly KILL YOU. Many use plastic pipe but, don't realize the dangers of it's use. There are several systems on the market with Aluminum pipe and specialty fittings but htey run more than Copper pipe. There is also nylon tubing good for 150PSI it dosen't go up very well but, I would use it before I ran plastic piping. Search the internet and you will see some good designs at Ingersol Rand and Chicago Pneumatic compressor sites.
I use aluminum hard pipping that uses quick connect fittings. I have several points thru out the shop that i can a air hose to as well as 2 reels in the ceiling. I have found that this works great and I have had no leaks not to mention I can easily add incertion points anywhere along the line.
I have done it with iron pipe but don't recommend it. The couple times I have done, I have ended up with a pinhole leak somewhere which drove me nuts. The last time I did it I used copper and it was fast and easy and no leaks. Being there is no water in the pipe it solders up quickly. At each end point I soldered on threaded ends, and went over to Farm & Fleet and picked up all of the fittings and put them on with tefon tape! Worked great, and is easily expandable. I saw comments above stating that plastic was dangerous but I really didn't understand that either as I believe water pressure is tested at 300psi, and most compressors don't provide that kind of pressure. You really only need a system that will hold around 150psi, and I have seen plastic used even in industrial appliactions for this. I prefer the copper because it is soldered....I have had very few solder joints ever fail but I have seen a few plastic joints fail in my time.

The problem with Plastic (PVC) pipe is that when it gets cold or sits in sun it becomes very brittle and depending on the air pressure can explode into tiny peices. If you see PVC pipe used in an industrial application you can bet that Osha has not been there since it was installed. (not that I am a fan of Osha) but I have seen what this stuff will do when it explodes and I know I wouldnt want to be near it.
I just took down about 150ft of pvc that had at least 10 drops piped in and had 150psi in it daily for the last 14 years.
Never a leak and no explosions.
I used a knife pvc type cutter to remove and it was definately more brittle than new. Wasn't worth saving the pipe.
I'm not recommending it, but I plumbed the new place with it too, sch 80.
Copper is best though.
I just ran air hose across my garage and down into the workshop in my basement. I have a black iron manifold with shutoff valves at the compressor and filter/regulator/quick connect assemblies at 3 spots. Its held on the wall up near the ceiling with 1/2" emt straps and cut to length so it's out of the way. I was thinking about running iron pipe all over, but it just seemed like more work than it was worth. If a hose does go bad for whatever reason I can pull it out and replace it in about 10 minutes.
I was thinking of iron pipe but the comment about the pinhole leaks is making me second guess that.
I didn't even think of copper. It might be more expensive but it's really easy to cut to the lengths you need and solder the joints. With iron pipe you have to cut then thread or you end up with a lot of unions and short pieces if you try to buy pre-threaded pipe at a hardware store.
I also didn't think about making a manifold and using hose from it to the work.
I have a couple weeks before I'm ready to install it so I have time to think about what will work best for me.
Yep I'm sticking with the hose hanging from the wall as I said early in the thread. It's always available and works fine...whether I'm in the garage or out in the street.

Thanks again.
All of the air lines in our factory (a large electronics company with a big M logo) are plumbed in copper...that is where I got the idea. The iron was a PIA when I did it. Getting exact lengths and lining it up while not breaking the seal was not easy compared to when I re-ran it in copper. when you consider all the nipples, different lengths, etc. I don't think the copper came out to much more. It was far easier, faster and better in the long run. I am thinking of running a line into my basement for use with the furnace, etc. I agree with the comments on plastic if in the sun. Sun is PVCs worst enemy. If it is indoor, especially in a wall I think you would be fine.
You want metal because it cools the warm compressed air as it goes through the air line. That allows the moisture to condense and then it gets caught in the moisture trap. That's how it's supposed to work. That's how you get nice dry air. You should have at least 25ft of pipe and drop downs, etc. I doubt PVC will cool the air down enough to properly separate the moisture unless you have really long runs like might be present in a large shop or factory. I think copper is easier to work with. I know guys that have had iron pipe for years w/o problems. Here is a good link: http://autobodystore.com/forum/showthread.php?t=13858

That will work to a limited degree or until the pipe warms up.
It's all about dew point.
If you are serious about dry air , here's the dryer, refrigerated.
Bought one on eBay for 140 bucks used.
