Some of the posters here, seem to describe brazing as the work of the devil. I have been hands on in repair work on vehicles and machinery for 49 years, brazing, bronze welding, etc. were all methods taught to me and have used them during my working life where required. There will always be a bodger around who misuses techniques making it harder for the next person to recover a bad repair, but that is life.
Just so some of you can look deeper into the technique, here is a link to a company who supplied products in the UK:
