If silver soldering is like soldering I will be able to do it ok, as I can solder ok. I made my track via soldering the track to PCB sleepers. Ok, my soldeting is not neat but it works.
Except for a few trick alloys, silver soldering is done with torches instead of irons. The miniature butane torches can do very fine work. It is the same process of cleaning, adding flux, and heating both sides so the solder can flow, either having a chunk in place, or feeding it in. I do it in dim light, so I can see the temperature by the colour of the glowing metal. There's more oxidation to clean up later, but you can minimize that with more flux, which washes off in hot water after turning to borax glass. Unless you are filling a tight gap like a bicycle lug just to the edge, there will usually be blobs to file off for the neatest appearance, although you get neat fillets of small radius automatically.
Torch work is also great for jobs like annealing brass to make it easy to bend again after working it too much.
Just be careful with fire, and use pliers to handle the hot bits on the way to a water quench. A bit of firebrick or something similar is handy to arrange things on, but I often work with just a vise.
