bike carb manifold- best way to make them?

right ive got the 1.6 carb engine from a mk1 with 4 speed box, ive recently bought suziki 600cc carbs and im wondering what the best way to make them is? get a metal one made? or im sure people also make them from other materials?
which is the best way?
and could i pay anyone to make me one?

u could go to loads of different places m8, best thing to do is a search on here for a thread by mixer man he done a home made job that worked very well, not only this your get a rough idea on who could help you out in ur local town, any sort of metal worker would do or even anyone who could wield there quite simple in design, theres a bit scenice to it, as the longer or shorter the tubes are can affect performace in different ways i belive

take a look for mixermen 1.3 on bike carbs

hope this helps
