On the serious side, those are some nice circles in your chassis pieces, Art. Very very professional and nice looking.

I can't take credit for that chassis design, as that chassis was mostly from 228's previous mechanical engineering mentor. However, I will be working with the students and other engineering mentors on 228 over the fall to prototype a similar frame design for potential use in future years, as we really liked working with CNC sheet metal designs. Ideally, our goal is to design a modular chassis that will need minimal tweaking each year, much like that of 25 or 173.

But the main reason why those holes look professional is because they weren't done by hand; they were made on a CNC machine - hence the reason why I posted them in this thread. ;-)
