i know on the old forum someone posted a how to for melting lead and making your own surf weights. i just scraped up about 3#'s of lead and would like to make a few spider weights. i remember reading in that post something about sand. i know about not mixing water and hot lead, use a fan to blow away the fumes, wear protective equipment, etc. but can't remember what to do with the sand. any help? thanks in advance!
