I have used my Tig-set with a brons filler material to braze steel furniture and some interior window frames and doors for clients. I liked the idea of brazing, since I have done this a lot in the past (some 50 frames) and clients liked the color of the joints.

Has anybody tried to Tig braze bicycle tubing?

At this moment I don't have a shop. I would have tried it if I could.
