    Pewter is my main source of cheap tin. Second hand shops etc. Scrap metal dealers have the occasional printers lead which is high in antimony. To test the hardness of your alloy use pencils as follows. If he pencil will scrape the alloy it is harder.

    6B = Pure lead, about 5 BHN
    5B
    4B
    3B = 1in20 tin/lead alloy, age softened, about 10 BHN
    2B
    B
    HB = Lyman no 2 alloy, about 15 BHN
    H = Linotype, supposedly about 22 BHN,
    2H
    3H
    4H
