Brian's instagram site has some really good short vids on brazing(lug mods too), especially good are the close ups of his techniques. If you go to his site run your cursor over each pic, if an "arrow head" appears click on it, the vid will start. These types of frame brazing vids are pretty rare on the net, definitely worth a look. If you see torch work on one of the small pics most likely it has a vid, but check all if you're interested in other processes.
