Now that all the links are made................
Pickle and rinse all the links to remove any fire scale or light discoloration. Rinse and dry.
Use 320, 400, and then 600 grit sandpaper or sanding pads to clean and refine the solder joins where needed.
Tumble in shot, water and a drop of dish liquid for several hours.
Remove the links from the tumbler and rinse. If the all the parts of each piece are still attached, the solder joins are likely permanent. If not, the old solder should be filed off and the pieces soldered together again.
Pro Tip: Wait to patina until all the links are connected in the desired manner.
