talking of silver solder, my dad worked at westinghouse for 40+ years in the copper shop and over time some of the extra silver solder found its way home here.:biggrin2.gif:
there are 2 main types that i have on hand the first comes in a round rod form and when heated it tends to flow and fill gaps and the second is a squared rod type that you can bild up and fill in with. also have a limited amount of a third version that is a thin paper like wafer, he said when you had 2 large flat surfaces you would lay this between thme and heat it up and when done was welded fully on the inside
