This was more of a try/can I do it, not really to rescue the part. I've successfully brazed aluminium so thought I would have a go at some dubious thin cast? broken latch.
Had Oxy/mapp at the ready but impressed that Rothenberger superfire 2 torch with map plus gas got the metal yellow in short time,, lot to do with the vermiculite stove bricks I guess and only 3.5mm thick material. I did clean it before hand!
Anyway, really chuffed with one side, let it cool slowly, very strong joint. Flipped it next day (no pics) and put some thin steel plate under the brazed side - it melted the previous braze and stuck solid to the plate - stupid I know.
Question is what is the procedure for doing both sides on something that thin, or is braze not the right option?
