As previously mentioned the Manifold was made the hard way by bending 1.5" x 14g tube on a hydraulic pipe bender.
I made up a jig to duplicate the position of the head and front side rail of my MK chassis because this method needs a straight length tube before the bend.
The exhaust port positions on the jig were clearance on 1.5"so I could pass the pipe through & so get the bends right before cutting them to length.
Manifold was tacked up and tried on the car before final welding by a work mate - I am no welder !!!
Tubes were packed with sand to prevent them collapsing, Rortys site was very handy, but it still took several attempts to perfect the packing techniqe & then to get the bends correct.
The lengths are not the same and there are several uniformed kinks around the bends but its still better than the cast iron original - is'nt it ?.
With hindsight it would have been easier to fabricate it from bends, this method was very time consuming and difficult to achieve the end result, but I had the hydraulic bender and purchased the tube so had to persevere!
Also finished the brake lines over the holiday, fuel tank is next - hurrah !
