Thanks for all your comments....to answer some of the questions:
First of all i hope to use riveting to secure the frame members, however some people on my team prefer bolts, we shall see who wins

.
For the bend radius...im actually not sure, i used the presets in Autodesk Inventor and i believe it is 0.09 inches?
At school we have a sheetmetal brake, so I was wondering if it would be okay to get the parts CNC'd and then bend it on our brake? This would save us a lot of time as it wouldn't need to be shipped out to a sheetmetal shop. Any thoughts?
Also, yes we will be adding a plywood baseplate and another cross member.
