In my adventures taking aircraft maintenance classes at Mount San Antonio College, I've learned a lot of things. Not the least of which, is how much I have to learn!
Another piece of knowledge I'm grateful for, is how to drive and set solid rivets. I'm not the best at it, but I can do it, and practice will make me better.
One thing about riveting has been indelibly etched in my brain. Rivets require precise holes to be properly fitted. So much so, that a rivet is often referred to by the drill used to make the hole it fits in.
For example, a "30" rivet is a 1/8 diameter rivet, and uses a #30 drill for it's pilot. A "40" rivet is 3/32 in diameter, and uses a #40 drill for it's pilot.
