Chuck,
Zinc chloride flux is for lead solder and won't work at all with silver solder. Also, the 45% solder you have is probably not going to be strong enough for bandsaw blades, you need some that is at least 50% silver.
You should be able to get the right stuff at a welding supply or at the following link:

The solder should be 50-55% and the paste flux say that it is specifically for silver brazing.
