I'm probably going to get them anodized and then silkscreened, so I guess I'll only need the parts deburred somehow. No need for engraving or changing the thickness - we don't need to get too fancy.
Another possibility is having someone cut just the perimeter and the four outermost mounting holes - this is what will be common across all of the panels I'll need - and drilling the rest myself. Of course, that assumes I know how to make drill fixtures for something like this! Anyone have any tutorials?
Thanks again!
