My personal favorite is the
pneumatic rivet gun our district bought for us a few years ago. A Godsend for the unfortunate soul tasked with installing 100+ rivets on assembly day. One can install many dozens of rivets a minute working casually
Funny story about this, in 2013 we needed to replace a whole bunch of rivets in short time on our shooter mid-competition. We didn't have our shop compressor at competition (pesky rules) so we installed a quick-connect fitting to our robot and used it to operate the rivet gun. One of my proudest moments.
