I agree! See team 330's 2006 robot (shooter frame) and 2007 robot (ramp frame). You can't put a lot of holes in, though; it has to be welded.

[quote=dtengineering;650586]If you can't TIG or MIG in-house, then keep in mind that somewhere in your community there is someone who wants to weld your robot for you. People who like welding tend to like welding cool things, and competitive robots are generally regarded as a pretty cool thing. Perhaps a local community college or trade school can help you out./quote] Some machinists are also like that... In the case of some SoCal teams, one such is also an instructor at the local community college. Shop use and he could make parts for teams--not a bad deal.
