[BC] recommended fluxes for silver soldering ground system/radials?

[Alan Alsobrook]

I use 15% Silver Sta-Sil Or something like that (same stuff Cowboy 
mentions) and a Oxy-Mapp torch. Oxy-Mapp gives you right at the same 
amount of heat as Oxy-Acetylene but you aren't running back to the 
welding shop every day for a new tank of fuel. I've brazed up 2 120 
radial ground systems and still have about half of a 20# tank of Mapp left.

As far as flux, I seldom use it. It's only needed if the copper is 
really old and cruddy. When I do use it it's the white paste stuff, but 
I can't remember the name.

For a small job like the poster talks about, he can get one of the 
Bernz-O-Matic Oxy-Mapp torches at any hardware store, just be sure to 
get an extra oxygen tank or two. No flux should be needed. I used (and 
still do from time to time when I don't feel like dragging out the big 
torch) one of those small torches for years and it works wonderfully. I 
did cheat and use a medical O2 E cylinder @2-3Lpm in place of the small 
home cans just because it saved lots of money.
