Here you can see the way in which the header tubes have been curved and 'woven about each other' in order to ensure they are all of equal length, they then go into a four into one collector. Everything here is hand fabricated except for the actual bends in the tubes which are created by using 'Mandrel bends', available commercially (e-bay) in 30° 45° 90° and 180°bends, in varying lengths and inside diameters. Terry used stainless steel.
