Hello and welcome. I don't have much advice on building a flight as the one flight I helped build had to be replaced after a few months due to chewing by the birds. I would go with a commercial flight. They will be cheaper in the long run and you know that they are well built.
If you plan on breeding, don't do so in a colony setting. This will make it so the offspring are difficult to tell who they came from. If you keep some of the offspring, inbreeding would be a real concern not knowing genetics or which birds are mating with whom. They will not discriminate with what bird they mate with.
Also, commercial bronze being an alloy of Copper and ZINC can be dangerous to your birds. Zinc is toxic to them, so I would be EXTREMELY careful with what you use to build the flight.
Bronze is typically 88% copper and 12% tin.[4] Alpha bronze consists of the alpha solid solution of tin in copper. Alpha bronze alloys of 4–5% tin are used to make coins, springs, turbines and blades.
Commercial bronze (otherwise known as brass) is 90% copper and 10% zinc, and contains no tin. It is stronger than copper and it has equivalent ductility. It is used for screws and wires.
