I am currently designing a sheet metal chassis for next years competition, and would like some help. I have a couple of questions:
1: What thickness of sheet metal should i use? I currently have .060", but I am not sure what thickness would be the optimum balance between lightness and strength.
2: Should I use a round or cross hatch style lightening pattern?
Thanks so much
