Thanks for all the replies! Sorry I have not responded yet, I have a habit of forgetting to post... so I will reply to all the posts in one post.
Travis Schuh: Thanks for the tip, I was actually thinking about doing just that, but I'd have to see how I could get a CNC mill to mill those tight corners.
AllenGregoryIV: Yes! I have seen your robot, the sheet metal work looks
fantastic! I really admired your robot last year. Thanks for all the great links, I will look into them when I don't have homework piled up... (tomorrow).
Sanddrag: Post taken into consideration, thanks for clarifying.
jspatz1: PM sent.
Akash Rastogi: I will send you an annoying amount of Facebook messages if the need arises, thanks for the offer.
Roystur44: I think we would most likely be using 3/16" rivets and screws. Your addition of dual lock at the end of the list intrigues me, I will look it up.
Thanks for all the great replies! I will work more on the CAD model tomorrow and post an improved corner!
