I just picked up an new 80 gallon compressor and new sand blaster gun ($60 for the gun and $40 for the carbide insert) and need to run some airlines. I can’t afford the Garage-Pak system that is advertised on Power-Block. I was thinking of 1/2″ black pipe and was told to go with the galvanized instead. What works good that is reasonably priced? I only need to run about 20 feet for now.
