[ZeroValue]

We are using 2x1 with 1/8 side walls for the main frame members, and 1x1 with 1/8 sides for the two cross pieces. We haven't done any testing, but we are confident that it will hold. Last year our robot fell off the wall for every match, and we had over 20% more material webbed out. there is a forum somewhere here about basic cad for that robot that i posted when I was still green with the cad design/f.i.r.s.t., search for "tator".

The weight lost/cnc time ratio is fairly low. It's mostly a way to get some experience with the small cnc mill in the shop. Last year we sent the cad to the micron shop and had them machine and weld it. This year we plan to do more of it in our own shop. All of the kids in the shop during the off season mechanical team meetings have some experience with manual mills/lathes. We just don't know anything about the cnc part.
