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?
