"The only issue is that solder requires a bit more heat
then the leaded solder."
To get adequate heat when using silver-solder bars, one option is to use a small acetylene cylinder tank with a single line torch kit. The typical air/acetylene temperature is about 1000 degrees F higher than propane/butane. That's often enough to reach the bar's melting point when the connection is heat-sink limited (e.g., bonding wide copper ground straps).
I once tried oxyacetylene (a pure oxygen + acetylene mixture) and had a disastrous result. The torch temperature rises rapidly with even a small volume of mixed oxygen. Good for some welding applications, but not silver-soldering.
