I finally bought a new compressor, an Ingersoll Rand 230V two stage T30 60 gallon, best I could afford, I'm excited. Planning on air lines, trying searches and found some cool pics of copper air manifolds, found a how to on TP tools. Question I have is I only need about 18 feet of pipe, thinking of using copper, isn't there a minimum you should have? The longer the line the cooler the air and more moisture gets out? Copper is expensive and would be happy to get away with only 18', but is it enough? Second, how well do those manifolds work getting the moisture out? I figure if I build one, the copper and fittings would run about $120, still need a filter anyway.
