None of which changes the fact that the reference you provided was simply WRONG, and unsafely wrong. An ISO 4038/DIN 74234 "bubble" flare is nothing like a half completed SAE J5336 45 degree double lap flare. Here is a somewhat authoritative document (it's from a brake line importer) showing different flares - http://www.fedhillusa.com/webnuts/common%20flares6.pdf Who knows what angle is created by any particular SAE flaring tool on the "half completed" part of the flare? DIN/ISO specs call for a 115 degree angle, with a 1 degree tolerance. There is no specification for a "half completed" SAE flare, so even if one guy got it to work for his purposes using the particular tool he had, there can be no guarantee that any other tool would produce similar results, and certainly no guarantee that any flare done that way would seal properly under full working pressure. I certainly wouldn't drive a race car built by someone who used that method. (Oh, and if you want your grammar freedom to not properly quote and attribute information, then you must take full credit/responsibility for whatever you write)
