Silver soldering and bracing is an important method for DIYers as it is cheap and makes very strong joints.
Al always, practice is important and I have just found a superb video explaining the technique with a great detail and educational view.
The video was made by Johnson Matthey soldering division (UK), which has a large amount of different silver rods and fluxes for all materials. The video is available both in English and Spanish.
Hope you enjoy them as much as I have:
I will shortly order some rods and flux to practice as I have the intention of a mid term project consisting in a tubular stainless steel frame for a radio control model airplane fuselage
