Brazing my first cable guides on a bicycle.

Back in May 2019, I had never brazed a single thing in my life. I learned how to braze by watching many videos online and asking questions in bike-building forums. Watching this now is a bit painful, as I had some knowledge of what I was doing but didn't really understand the finer points of brazing. I filmed my first attempts at doing this without any formal instruction. So, my technique back then is rough. My tools were cheap and minimal. I didn't have a proper acetylene torch; I just used a Benzomatic with MAPP gas. I learned right off from showing people this video many things I was doing wrong. I didn't know how to properly use a file. Files work in one direction - not back and forth. My flux use is too heavy in most of these examples.
