Im with ^^^^. let him do what he wants to do. If they work and dont cost too much then im sure ppl will buy. Theres no difference in him making hinges, than anyone else on here who doesnt have the money to buy a hahn or star turbo kit and putting their own kits together from misc parts. Yes it may not work quite as well as a hahn or star but it still works and no one bashes them for doing that.
