Default Re: what silver-solder to buy and where?

I got mine from a welder supply store. It's pretty expensive, the last time I bought it. I think I picked up a pound spool in 1980, still have some left. You will also need to pick up the flux that goes with it. The flux will let you know when you are getting close to the correct temp. It will turn to a clear liquid. The store should be able to give you the melting points. Higher the silver content lower the temp will be.

I use a oxygen/acetylene torch for my brazing and soldering. I DONT think a propane porch will get hot enough for what you want to do. I don't recall what the actual melting point is, I think it around 800F. I do so little with the 60% ag. I use a 5% Sil/flux for refigeraton lines. It melts around 1200F.

Unless you really want that much strength, I would stick with the lead solder. You can get at any home improvement store. And you don't need the oxy/ace torch. In water lines the strength comes in the joint design.

You are not going to have any pressure to deal with, use the easy stuff.
