In 2012, 1370 built their frame out of 2"x1" aluminum box with 1/8" walls. We then bought a 1-3/8 hole saw and had students use our Bridgeport vertical mill to lighten the aluminum parts at very precise repeated intervals. The end result was a robot which was 119.9 pounds without a shooter.
Of course, that also meant we could balance with anybody on the bridges and we could move any fender-shooters off their mark without any real effort....
In 2012, we used 1" square 1/16" wall aluminum box tubing and worked up a pretty decent offensive robot.
Moral: Never using 1/8" wall aluminum tube again.
