For small braze-ons it is best to use silver brazing rods, and for structural modifications use bronze. You'll want some welding glasses, leather gloves, and whatever frame prep tools necessary. Also, buying a small respirator will cut down on breathing any flux fumes. Really that is it! | |

Given the problems with MIG I will still experiment with it knowing that I can ruin the frame. @WTHarper (or anyone else) for brazing are the small Mapp Gas + Oxygen canister set-ups workable or do you really need full sized tanks with Acetylene, etc to get something done? | |

You find a few very high quality producers (Waterford, Rivendell) still making brazed frames; more importantly, however, most home builders use a brazing torch. MIG welders are cheap and easy to use, though, and I'm sure many people have modified bicycles with no complications. | |

Brazing tends to be the standby for most hobbyists (including me) because the equipment is easier to setup, it is cheaper, and it is harder to ruin a bicycle (though not impossible). | |
