Those plates are going to be hell to manufacture. You're going to need CNC machine tools to do so.

Consider making all rounded/angled surfaces 90* angles and you could do it manually. Also, the right side plate is going to be REAL hard to make, seeing as you're going to have to start out with a solide aluminum block and mill it down so that it's got the angle on the bottom, unless such a material is already sold that I'm not aware of.
