thy need not be fake . I did away with the metal mine was a length of alli rod . Bending and getting the angles rightwas a bit of a take on . I used evergreen plastic pipe the same dia. made up templates and then cut and glued then . To get the angles around the superstructure . I turned my bends using the Lobster Back method its a bit fiddly but you get a more realistic turn . I still have the templates but if I am not exactly the same as yours thy will be no good . After I made them up I pressure tested them so if at a later date I wanted to use them I could . please PM me if you need clarification on lobster back pipe turns .
Regards David
