Welcome to our humble forums!
I just wish I had more time to bild the things I want to build myeself... Rivets have many more advantages over screws as I have done about four or five screw builds (well two of tose was just the drilling and tapping) and those little taps just don't like tapping hardened steel... You can see some of my thought on that here:
