jig man has given you sound advice,all i wanted to add is that you can make molds out of plaster of paris(spray the mold with a sealer,or spray enamel to make your baits turn out smooth) or bondo. I decided to do exactly what you are comtemplating a few years ago and although i got quite a few usable baits out of my scrap it just wasnt something i enjoyed. Ill stick with pouring lead and carving but to each his own
