I've heard the term "nice brazing" used here before, but I've never been sure exactly what it meant. My curiosity as to what good/bad brazing is was piqued again last night while reading the recent "Modern, Skinny Tubed Steel Frames Vs. Vintage, Skinny Steel Frames" thread. Raleigh and Peugeot were both called out as being notorious for poor brazing on some of their models in that thread.
So who wants to talk about brazing? What exactly does good/bad brazing look like (pics encouraged)? How does one judge the quality of a braze? Does poor brazing imply a weaker frame or is it mostly just aesthetic? How does filing/milling factor into the quality of a braze? Inquiring minds want to know!
