If you do go for it, make sure that all of your work is done outside or in an extremely well ventilated place. My cousin, who is a sculptor trained in metal pouring, said his instructors told him to never, ever work with lead.
I would avoid it if I were you. I've had high levels of lead in my blood and the process to reduce it are expensive and takes months. It's not worth it.
Please remember those who gave everything they had.
