I made one for my A2 project. I would really consider wether its worth it, its a very challenging project which requires stupid amounts of time, frustration, MONEY, skills and lots of research. I wouldnt bother for GCSE, make a well made wooden box or something easy like that and you can still get all the marks. The problem with my A2 project was that it was very complex and the examiners didnt understand a lot of what I had done (Remember a food teacher could be marking it ) Dave
