I've followed this guy's writing about the 1911 for a long time. He might sound a little hillbilly, but his information is solid. He's known as John Travis, aka 1911Tuner. Take a gander at this video demonstration of how to take a 1911 apart completely and then put it all back together:

What I love is his high-tech "armorer's plate."That was amazing. Other videos make it seem complicated.
If anyone is interested in reading up on what John Travis / !911Tuner has posted over the years, one can "google" either one. He's posted his 1911 knowledge under both names across a number of gun forums.
