I have silver brazed some fairly large assemblies for 3/4" scale 3-1/2" gauge locomotives using nothing more than a common Presto-Lite plumber's torch. And I have watched some oldtimes braze a large copper boiler for a 3-1/2" gauge Pacific with one fellow using a Presto-Lite torch and another adding supplementary heat from a propane torch used by roofers. It is VERY easy to burn the pieces you are silver brazing if you are using an oxy-acetylene torch. If I were advising a beginner in Gauge One building....I don't think I would recommend oxy-acetylene. Even fairly large assemblies can be silver soldered with a plain propane torch, and if you need additional heat, you can get a "Turbo-Torch" that uses a swirl tip to generate much more heat that a plain propane torch. While I am sure in the hands of an expert, very fine silver brazing can be done by an experienced person, with an oxy-acetylene outfit....I think a beginner would end up giving up after they ruined their hard work fabricating cabs and saddle tanks. I am also reasonably sure that for parts that are not part of the presure vessel, such as boiler jackets, cabs and details....soft soldering is more that ample.
