I just got some silicon bronze for trying out tig brazing. I also got 2% thoriated tungsten. Anyone have any experience doing this? I was going to try it out with the intention of brazing the side rails to the main tube if the results are good.
Tried it out on the hole I messed up on. It looked ok and I was able to machine it but the filler came loose when I blew out the hole after drilling. I will try it again with more heat just to see if I can make it stick better.
