Silver soldering advice

[Stuart Giles]

One other thing that might be worth adding to Derek & Duncan's comments is that sometimes, no matter how carefully you intend to work, silver solder running somewhere very close to your joint (like a threaded area, or some knurling) might still ruin the job. Paint some Tippex, or one of the clone typing correction fluids onto the area where you don't want the silver solder to go. Traditional Tippex or similar products will discolour under the torch but will not burn off, the solder will not flow on the areas that you have painted. A mate of mine uses Milk of Magnesia which apparently works the same way, but I haven't tried it myself.
