do they need to be inset as in the drawing or will a flat piece of aluminum work?
I have some .25 thick aluminum. I could mill a pocket which would add to the design and then mill the holes for the components. That would take more machine time is all.
Generally, the way I mill plates such as these is I surface a piece of scrap and then glue (using superglue) the stock down onto the scrap. I can then machine around the edges without worrying about clamping. With pockets though, the torque even when ramping down might break the part loose.
How many plates are needed?
