I've also read from other sources that the head tube should be reinforced for fillet brazing.
So my question is what are my chances to get away without chosing a stronger tube and with no reinforcements. And if I actually should add something to make my head tube stronger, what should it be? Should I braze on a couple of rings on the ends of the head tube in a similar way the lugs are brazed?
I've not had problems fillet brazing a standard head ube, but I do like to use some of the scrap from trimming the head tube as a reinforcement so ham-handed headset installation won't be as likely to distort the head tube.
