Having been a helicopter mechanic for over 15 years I can tell you that they vibrate, a lot, and have thousands of rivets. Yes, they are very different from the hardware store type, are put in with tighter tollarences and require special expensive guns to install. However, it is not hard and does not take long. If someone wanted to go the rivet route what I would suggest is go to your local airport and talk to the mechanics at an FBO (fixed base operation) and explain what you are trying to do. They will have the guns and rivets and the technical experience. And I would bet they would jump on the chance to drive rivets into a Raptor. Probably cost beer at the most.
