Hirose does everything the hard way. Go watch him make a crank, for example. I have wasted way too many hours watching his video. I don't think it's a commentary on any other method, it's just the way he does things. I'm thinking I have seen him fillet stems, for example, and that's probably the most critical joint on the bike.
I want to make some lugs the way the pressed lugs were made, just bent with a hammer and punch around a form. And then welded along the center line. No good reason, it's just something I keep thinking about doing.
