Just a quick update.
You know that feeling when you want to get something right, but you go too far into unknown thinking you can do better than it's done...
Well i welded canti bolts in place with inox for strength and then tried to get the welds brazed for extra sleek look. Big mistake! Apparently you can NOT braze inox. If only i knew. Now it looks extra tatty. Same thing happened on two small holes, seat stays and fork. Tomorrow it finally goes on galvanization, with my luck zinc probably won't stick on inox either. N.B. lesson learned: brass and inox hate each other!
INOX is a generic term for corrosion resisting steel if I'm not mistaken. I haven't encountered a stainless alloy that couldn't be brazed assuming use of the right flux.
Perhaps you didn't flux the weld area you were trying or braze over?
