I recently did this reversible mold modification and thought that it may be of use to others. I used high temp. silicone to create a dam so the lead would not fill the collar area of a Do-it Poison tail mold. I also filed in a groove on either side of the hook shank to allow a straight piece of stainless wire to lay when the mold is closed Later, after the head is molded, the wire will be bent to create a hook keeper On this mold, the first step was to create the channels next to the hook shank for the wire to lay when the mold is closed. I used a round, fine tooth file. The diameter of the portion of the file was approx. 3/16" (tapered file) Carefully remove the corners but do not deepen the shank channel (see pic below) I actually needed the aid of an magnifying glass to see what I was doing. You get a good view of the wire channel next to the hook shank in this pic I then poured some dummy heads, minus the hooks. I cut and filed the collar off, but left the sprue on to act as a handle to remove the head. I degreased the mold collar area with solvent to assure good adhesion of the silicone I then used petroleum jelly on the dummy head to prevent the silicone from sticking to it and set them in the mold I overfilled the collar area on half the mold and let it dry overnight
