going to be venturing into making my lines for my air system, was reading aluminum is good for no corrosion and other things, I have a 150 psi craftsman compressor at the moment, not sure the size the lines around my garage should be. going to do the zig zag pipe to help with dissipating the heat and such. I plan on going to a 80 gal soon(maybe tax return time) , not sure the difference on single stage and dual, but will hopefully be that eventually. I know the size of the pipe can affect air flow and pressure. Any help would be great!
