Hi Bazmak,With a copper boiler that size i would recommend the large brazing torch for the main heat source
COMBINED with oxy acetyline for local heating and the actual silver soldering.With copper the heat
disapates quicker than you apply it.And you need local red heat for the solder to flow.Plenty of rivits for location
and they must be soldered also.Biggest boiler i have made was 4" with 1/8 wall. Like running a marathon
in the Desert.(O AND YOU WILL NEED A CASE OF THE BEER) Bazmak
Good advice.I have a 4" Vertical Boiler yet to be silver brazed.Sure hate to see same done half baked. Your advice confirmed my fear of not having enough fire-power on hand.
Now in hobby machinist paradize----HongKong. Found sources for cutting tools and dividing heads.Machineshops here preferred Japanese or Taiwanese tools for reliability over Chinese tools. European made is high on the preferred list.
