Remove unneccessary hardware. (got a 1/4-20 bolt holding on a lexan shield? Remove it and replace it with a ziptie/barlock)
Back in 06 I made a few students nervous when I went around the robot pointing at various nuts and bolts, telling them to take them off because we didn't need them. Took off about 2 pounds worth of 1/4-20 bolts that way . . . only then did the drilling begin.
