I think I may have misused the term silver solder.  I should 
have said "silver braze", since I am not talking about a 
sliver bearing (i.e. 2% silver) low temperature tin lead 
solder (that you can use with a soldering iron), but with a 
silver alloy braze that you use with a flux and a torch.  I 
think the high silver alloys that contain a little nickel 
are good at wetting both stainless steel and copper, and 
nichrome is really a form of stainless steel.  However, 
there are a huge number of silver braze alloys available, 
and not all are suitable for joining copper and nichrome.
