    Two answers depending on what you want to do: 

    For short coils of jump rings (i.e. ~3", for use with Dave Aren's
    Koil Kutter, or the standard version of Ray Grossman's Jump Ringer),
    get some transfer punch sets. Four different sets that can be had for
    a modest price from www.use-enco.com will give you as many sizes as
    you can ever use. See page 615 of the online pdf catalog or type
    "transfer punches" into the search box. 

    For longer coils (i.e. ~15",  for use with the high production
    version of Ray Grossman's Jump Ringer) get some lengths of drill rod
    from www.mcmaster.com. 3 ft. lengths of 150+ different sizes cost a
    couple to a few dollars each. See page 3396 of the online pdf catalog
    or type "steel drill rod" into the search box. 

    My tactic is to do both. I have all of the transfer punch sets so I
    can make any size I want as needed with the Koil Kutter. For the
    sizes that I make many thousands per batch, I have the appropriate
    piece of drill rod for the Jump Ringer. 

    If using either of these options is too much hassle, both Dave and
    Ray sell mandrel sets that are designed to work with their respective
    products. These are in a restricted, but very useful range of sizes,
    and are modified a bit from the raw stock to make them easier to use. 

    Have fun making jump rings!

    of calipers was (were?) on hand after knocking a 60pc set of transfer
    punches to the floor...
