: I've heard that a tinker's dam is a small amount of some kind of paste that the tinker places around the hole or crack in the pewter. The dam serves to keep the solder in one place until the solder can fill the hole or crack. After the operation, the dam useless and is thrown away.

1: In Knight's Dictionary of Mechanics we find the interesting explanation that a tinker, having a hole or the like to solder, erects a small barrier or dam of clay about the area so that his molten solder will not flow off. The clay, once its usefulness is past, in thrown aside.
2: ...tinkers, mostly itinerant, were a knavish, drunken and blasphemous professional class, during the reigns of the Yorks, Tudors and Stuarts. Blasphemy was their most characteristic failing and "damn" was probably the most frequent and most abused word in their vocabulary. From their mouths it (damn) became meaningless. Hence, to say, "I don't give a tinker's damn," merely adds a little intensive force to one's indifference....
