It may have been LDS BS, but I was advised against making my own.
Being a gun person, I mentioned that I might take some lead shot and make my own pouches... the theory was that unwashed lead would leave nasty stains on my BC.. not only unsightly, but toxic (should I decide to suck on my BC, I guess).
I saw using old wheel wieghts mentioned in another thread.
I don't know how easy it would be to "wash" the shot, or if that is even practical. I guess you could spray the lead shot with some of that Plasti-kote paint, but ...uh, c'mon how much money are we really trying to save here?
If you're diving wet, the amount of lead really shouldn't be
that much. If you're diving dry, well, what percentage of your expense are you trying to save?
Hey, maybe you could make you're own wetsuit out of old inner tubes?
