Re: pic: 4587-Sheet Metal Chassis
If this is your first time with sheet metal, definitely talk to your sponsor and find out what bend radius they recommend for a given thickness, as this will be driven by the tooling they use. Usually not a huge deal, but updating this after the fact can be somewhat hairy on complex structures depending on how you define your flanges.
Right now, your radii look far larger than what I typically see used for .090" Aluminum, although 6061 vs. 5052 would call for a larger bend radius. Generally, 5052 is recommended for sheet metal work, but some teams do use bent 6061.
