Undoing brazing - C15 front mudguard

[Tigerfeet]

As the piccies shows, the brackets on my front mudguard are both spot welded and brazed into position. (The dull custard coloured splodges is bright brass in colour when scratched.)

I've drilled out the spot welds. Now I need a way of getting the brazed joints separated. I'm guessing the brass filler will melt again if suitably heated. Would I be able to get it to temperature with a plumber's blowtorch? Or do I need someone with oxy acetylene?

you will need oxy acetylene to melt braze quickly . although a plumbers torch will get hot enough to melt brass it will disperse the heat quite a lot . if you want to keep the mudguard without distortion i would use oxy .
