      I wish to change some silver soldered bushes in a copper boiler.
      I dont know what solder was used so I was planning on machining the bushes off then opening out the hole until I had removed all of the original bush (s)
      I was then going to make the new bushes to fit the new hole size and silver solder with a low temperature solder – idealy the lowest temp available – does anyone know what grade I would be looking for? and at what temperature it would need to be used?

          CuP do one that melts at 595-630 deg which is a bit lower than the commonly used Easyflow.

            In his book, “Model Locomotive Boiler Building”, Alec
            Farmer specifically cautions against silver soldering any boiler which has been
            put into service. He recommends using high temp soft solder. Page 187, too much
            to quote here. Best to check with your local boiler inspector to be on the safe
            side.

            Regards,
