[TowerTalk] Silver Solder

[Stan Labinsky Jr.]

When the potable water safety solder came out, I read up on it and saw that 
it claimed about three times the strength of 50-50 lead-tin solder.

Put up a two element co-linear, 5/8ths over 5/8ths, "J"pole for two meters. 
Bottom supported, stands ten feet tall made out of half inch type "L" for 
the upper element and type "M" copper pipe for the phasing stub and lower 
element. Put it together with that stuff back in '94. Still together today.

I've used silver brazing in high current pulsed power (well over 10kA...
lightning, a thin layer of silver/copper/tin alloy isn't going to melt
either.

I don't know about the mechanical properties of "lead free" soft solder
as used for plumbing with 5% silver content. I'd worry about brittleness
after temperature cycling.
