Yeah I used a curve then extruded down it, using different extrude settings so you dont have to mess with aligning the circle at the end of the curve yada yada yada. I also made sure that my curve ahd plenty of points so I could wrap it over the pegs and round the bridge. And I think If I needed to move it say the bridge angle I used a bend defromer so that it kept it all nice and straight.
