Sounds like someone is desperate to validate silver brazing, which is OK, but
it is totally entertaining to read this nonsense. How about the tube failed
there because it was a large frame built with a "B" tube set, and that is
where the butt ended, or any other of many droning variables that change from
one frame to the next. I have seen frames fail, kink and otherwise require
tube replacements, for as many reasons as there are frames. Those of us who
understand brass brazing, and have experience using it, know that this
business of villanizing brass is just plain silly.
All this talk to imply that brass brazing somehow ruins the tubing is
misinformed. Brazing is a discipline, and either you can do it, or you can't.
I would not want a poorly brazed frame in silver, any more than I would want
a poorly brass brazed frame.
