I'm building my on compressor racks, just need some pics for inspiration. I guarantee it will be my own design and not someone elses, just need to see what materials were used and how clean or wicked your racks look.
Do yourself a favor.. Get a engine driven compressor and hide the rest of the bullshit. Nobody wants to see your valves, tanks, airline, or water trap. Keep it clean. My Opinion.
Ive cut some mounts that look like a simple I they mount to, others were a tribal looking piece that was welded to the side of a tank. You can do whatever really.
