Ok I'm a ways away from needing one but we have some extra acrylic tubes, 4" dia and the machinist can build me one. Problem is I need some specs to give him. I don't know a thing about them yet, but the material and machine work is FREE. I checked some of the diy photos but I dont know where to put fittings or sizes. Any help on this would be appreciated.
