For some reason (I'm sure you can guess) my team took to calling hammers "fine adjustment tools". If you were to talk by our pit at nats you would hear us saying we needed to make a few fine adjustments, and be handed a hammer.
If it doesn't fit wack it really hard... that cost my team 4 hours waiting for the machine shop

when it's supposed to be a sliding fit, a hammer is not necessary.
That said, we labled our robot front and back. We spent 90% of our time at nats broken, and 60 - 70% of that time at the top of the white devision. At NYC we left our shielding all over the field our first practice. at nats we left a chain on the field.

I use that glass saying almost every other day, love it.
