Unless its two drive trains for going X and Y, you might want to get out the drill.

I second this, our 2012 robot was 78 lbs with the drive-train, and while making weight wasn't all that hard It was very limiting to us and caused a lot of stress. I would try to cut weight wherever you can, learning from last year we managed to got our 2012 robot down to 51 Lbs without any worries about structural strength. If you need more than 30LBS for a frame, you are doing something wrong.
