Choose the shape you want, trace it out on a piece of 3/4" wood....not any narrower. Cut it ou with a scroll saw or band saw. Router the edges with a roundover bit or a flat wood file, sand. Decide where the hooks will go, mark and drill a pilot hole. Use two weights, one an inch from the front, one an inch or so from the back. Melt the lead in with a propane torch, be careful, wear eye protection and don't get the hot lead anywhere near water. put the hooks in, drop the lure in a bucket of water. The lure should sink stead and level. Once you get the right amount of lead let dry overnight. Fill the weight holes with plaster, woodfiller, epoxy putty, or bondo, sand smooth. Dip the lure in a sealer, I like sanding sealer or polycrylic...let dry overnight. Dip in a white primer, dry overnight. Paint, let dry overnight. Two coats of clear. Done deal.
