Thank you Jim for passing on Harry's very to the point message on model
boilers. Also, Mike is quite correct that testing is of paramount necessity.
Those of you who are just learning about boiler making should read the books
available and not fear trying it. I think the most important thing involved
in soldering a boiler is the cleanliness of your joints. Being as copper
requires a lot of heat and oxidizes, the cleaning and fluxing of the joints
will be the road to success. In the actual soldering process, heating the
vessel evenly will also help prevent oxidation and premature failure of the
flux.
