Quote from ROKTOY Here's the couple of benders you can use. Available at most autoparts places I think. You can braze steel rod, tube, stainless, brass (solid) etc. You need to make sure the torch your getting is hot enough to melt the brazing rod you want to use. I use this material: You'll want a matching flux for the rod as well. I use: You can braze steel, stainless or brass to each other....no problem. I seem to be having a little better luck brazing the SS than the galvanized brake line. I usually try to sand the brakeline ends before I join them to get a better joint flow. Can't join aluminum to these other metals as far as I know.....at least with home shop stuff. Aluminum should be joined with aluminum. TIG welding probably the most common method. Quoted from Juggfucious One of the most important things when building an MT tube frame is to draw it out first. if you look at the way most real MT frames are made you can see for the most part they are 2 identical sides. All the frames i've built have been drawn out on paper before i started to cut or build. this way you get to see where the batteries, Electronics and links will mount up.. As for brazing, dont try and skinny out of the initial cost. Get a good torch. MAPP gas is ideal, and it needs to say it can braze, butane torches and others dont measure up. I use BernzOmatic prefluxed bronze rods. To braze a joing to need to fish mouth the joint (so that the piece are a snug fit). Clamp them together, and apply heat to the joint area using the torch. If you have water based flux, apply it before you apply the heat. Let the joing area become a nice cherry red, then tap the end of the pre fluxed rod to it. some of the flux will melt off and begin to flow in to the joint. Keep the heat on until you are getting an orangy yellow glow from the steel, then tap the bronze rod on again,keeping the heat applied. the tip of the rod should melt and flow in to the joint. Remove the Rod, remove the heat and allow to cool. You can dunk in water to speed the process, but the joint will be slightly weaker.
