Stop in for a cup of coffee

So chalk this up to another I should have paid better attention to my Grandfather moment.

Brazing: I need to add a piece to my chain saw muffler as part of this soup up kit. It calls for brazing the larger deflector to the outside of the muffler. Can this be done with a plumbers torch or should I break out the oxy/ace torch and go get a brazing torch end?
