You'll love silver soldering once you try it and are successful. The
whole trick is in getting the metal clean, and using the proper flux.
I would suggest not using the hardware store *kit* silver solder, but
use the welding store stuff. The brassy-looking stuff....about $16-20
per ounce...is real silver solder, the hardware store stuff that
looks grey and melts with almost any electric iron/gun is not, and I
don't think it's got the strength either. The flux is a damp paste
(that can be diluted with water if it dries out) that is applied to
the work (any ONLY where you want the solder to flow) then heated
with a propane torch and the solder applied. When heating the joint,
you'll see the flux bubble up and dry out, then turn watery again,
and that's when it's time to stick the solder into the flame and onto
the joint. It is very satisfying to see the solder flow (capillary
action) all around the joint, making a nice-looking fillet usually.
Have fun, Noel...SS'ing is a blast.

I take it there is a special tip used for silver soldering.

Special tip? Are you thinking this is a job for an electric soldering
iron or gun? The real silver solder I'm talking about needs 1370-1550
F. to melt. Maybe I was using the term "soldering" too loosely, but
that's what everyone calls it....silver soldering. Now I'm finding
that the proper term is "silver brazing". Here we go again with
people (me included) using terms from 100 years ago, while the rest
of the world has caught on to the new lingo. So silver brazing is the
"in" term, and it requires something on the order of a propane mini-
torch or butane torch to melt it. I just used a butane torch to be
sure I knew what I was talking about, and yes it melted it, and I'm
pretty darn sure that you won't find an electric tool that will melt it.
The stuff I use is Safety-Silv 45, and contains 45% silver, 30%
copper, and 25% zinc. The hardware store stuff that I have contains
2% silver and 98% tin, and melts at 450...(alphametals is the brand
name). That's why I say the hardware store stuff is not really up to
the task...ok, secretly I call it junk. I just did a google search
for Safety-Silv 45 and found, among others, a site at Home Depot
where a kit costs $28.07 and zooming in on their picture I see that
this kit has a small bottle of paste flux containing 1.75 ounces of
flux, and they show a small amount of coiled silver alongside of the
flux. I'm guessing that's 1 ounce of silver, so you can see the stuff
isn't cheap. But it goes a long way.
