I know it can be done, and I've done a search and found threads related to it.

My situation is similar. I cannot afford anything but a cheap MAPP gas torch like the ones they sell at the big box stores for about $40. I don't want to build frames with it. I *JUST* want to manage my own braze-ons. I do all my own mechanical work, and have no qualms about lighting a torch and melting some brass.
For example, I want to add canti bosses front and rear on a road bike I just got, and I might want to put track dropouts on it. That's about as complex as it would get, really.
So, what brazing rod would I use for this?
Edit: I found this in this thread:

For fillet brazing I use Gasflux brand rod #C-04 with Allstate 11 flux or Harris Black . The C-04 rod is apparently a popular rod for fillet brazing.
The nickle bronze I like is Harris #40 FC it is precoated with flux and is great for quick and dirty work like punk and junk bikes. I repair most everything ferrous with this rod. if you scrape off 2/3rds of the flux it will make neat strong fillets also but not the big fat ones like the C-04.
So does that pretty much cover it? Thanks for any tips and suggestions.
Don't worry I have junk frames to practice on...
