Hey all,
I am attempting to build myself a bike frame using Columbus SL tubing and lugs. I've started putting the sub-assemblies together, and my lack of brazing skills is quickly becoming apparent. I had trouble regulating the heat in the first couple of joints and the flux got pretty burnt. I also suspect that I haven't got good penetration in some areas of the joint, but the silver will no longer flow in, probably because the flux is toast. Is there any way of saving this (i.e. by soaking off the burnt flux, adding more, and trying again), or is it game over? Do I have a chance, or should I just heat it up, take it apart, and try again?

Thanks!
Neil
