You can tell where the area I put flux on ends in that picture, there is a layer of carbon on the steel. What you want to avoid is a lot of carbon where the flux was applied, that means the flux was overcome by heat. This is pretty good.

I really like fillet brazed frames because there is so much freedom in what you can do. This bike is going to have a curved top tube. That's the problem in taking the kids to NAHBS, they get ideas.
