Torch For Brazing Bike Frames at Linda Comstock blog

Torch For Brazing Bike Frames. Iirc pretty much any 5 or 10 liter model should give you enough pressure/volume to work a propane torch. The frame pieces are held in place with a jig, and the builder heats the joints one at a time with a hand held oxy. So the filler melts to connect the tubes, but the tubes themselves don't get hot enough to change. Oxy concentrator and propane beginner setup: Brazing is generally easier than welding and can be done at home with a torch. Brazing uses a filler metal with a melting temperature lower than the frame material. Steel tubing (such as focus of this thread) is fine for brazing into bike frames, typically using either bronze or silver alloy brazing rods which are higher strength than aluminum. It’s also less expensive to purchase equipment, but more. Typically, custom bicycle frames are brazed by hand. You find a few very high quality producers (waterford, rivendell) still making brazed frames; Heatsinks, as used for tig welding, are absolutely counter productive for fillet brazing.
