He used several 10 foot lengths of schedule 80 thick wall 6" PVC pipe plumbed together in a series as his "tank" -- he stuck these up in the attic crawl space.... and his "compressor" was a real good commercial motor and pump that produced plenty of air. His regulator controlled the "tank" psi to 125.
Schedule 80 pipe is good enough to hold 125 lbs (our working pressures)... but Google the ratings because this varies depending on the diameter of the piping and it's rating goes DOWN with diameter!
My guess is -- he spent as much on all the pipe and fittings and pump etc as he could have just gone out and bought a good compressor!

I thought about piecing a system together but figured sort of the same... at the end it'd cost just about as much but take a lot more of my precious time. Maybe I'll win Powerball tonight and this is all moot. Alternatively I can do nothing and maybe outsource more work rather than spend the money on equipment.
