| I've got access to Oxy-Acetylene gear and also a Brazing Hearth at work.
I was going to silver solder the boiler ends and threaded bushes using the arcosa gas air torch at work. The Acetylene is at home, I've only used it to braze and weld mild steel.
I would have thought there was just too much heat and the heat was too localized that it would distort and even melt holes in the copper.
