Interesting. Might I ask what the hazards are of performing the latter?

Answers my question (two of them, as a matter of fact; I did not know what the generally accepted term was for the practice). I'll spare you a photo of my Superior's BB, which was cut square on every single tube.
Might I ask what "today's standards" are? I assume it would involve about the same as the '61, but with a seattube fit and mitered directly up to the shell's inner diameter extremity, correct?
Take care,
