Most importantly is clean the components first. I use wire wool.
Position the components to be soldered, I place them on a brick with another behind - helps keep the heat where you want it.
Then, make up some silver solder flux paste, apply to the components in the area to be soldered.
I then use an ordinary blow torch, heat the components taking care not to allow them to move. When the flux has bubbled off, gently touch the components with the silver solder rod, if they are hot enough, the ss will flow into the joint, if it dont, heat some more and keep on trying until it flows. Once the ss has got in there remove the ss rod and heat and allow to cool. Clean with meths then wire wool.
Experiment first - you will soon get the hang of it, its quite easy once you get the knack.
Good luck
