well if you want to call it that lol. I have EVERY piece I need to make the top section being cut out. From the louvers to all the little hinge pieces and linkages to make them all work together. This part I didn't want to do by hand. The water-jet cuts with a .030" stream, so it will make each linkage EXACTLY the same, so the fins will open and close perfectly together (thats the plan anyways lol). Hydro Cutter is the shop I'm using. It's convenient because he's 5 mins from my house. This makes life a little easier :D
