What's the biggest fix you've had to do in between matches?

Myself and another mentor took apart the entire left side of our drivetrain and found that nobody had greased the gears, so during a pushing match, the already worn teeth had stripped off about 3/4 of the gear. Luckily we had some steel gears with us and were able to replace them and got them greased, the other side had been greased but we changed them out for steel and regreased any way.

Once some students got back we finished and reassembled the drive, but we basically did a complete rebuild of our drivetrain over lunch. Now people seem to think that aluminum gears are too weak for FRC, even though these held up for 1 1/2 regionals with NO GREASE. I am quite impressed they managed to hold up that long, and I am quite certain that aluminum gears, if grease properly are more than sufficient for FRC. I only wish I had a photo of all the shavings we dumped out of that Toughbox, it was quite hilarious.

My jaw just dropped and my boss just started laughing when he saw what i was looking at. that is seriously impressive. How well was it driving with less than half of the teeth intact?
