Saw a video with the Megabass Drunk Fly and liked the idea but it's not available anywhere except Ebay from Japan and I wasn't about to spend $25 for a jighead so tried to make my own. Did the clay model thing then made the mold out of Mold Putty (total of $19 from Hobby Lobby). Poured with lead it's 0.62oz and with pewter it's 0.42oz. It's not perfect but I'm looking forward to how it fishes with a spider grub on it. If it works out a buddy of mine has a bucket of hi temp RTV that I'll make a more durable mold out of.
