I work off a 1 pound spool. I don't have a bobbin big enough to hold it. The spool of lead just sits to the right of the vice. I pull off 2-3 feet of slack and hand wrap. The only time I cut lead is at the end of the wrap. Easy enough to wrap down the little tag where you start wrapping.

Use your bobbin for thread. It is more bother than it is worth to try to serve up wire of any kind with it.

For what it is worth, make sure to wash your hands after a tying session.
