After seeing the new swim bait molds and how the core is put into them, wouldn't it be possible to do the same thing with a worm mold? Put the metal rod in plastic, put it in the worm mold and inject with plastic? I realize this would have to be another special made mode. The same thing could be done with craw molds, brush hog molds etc. For a crawfish mold the insert could be coated in color plastic, put in the mold, maybe give the claws a shot of clor , close the mold and inject! Could open up a whole bunch of molds, but remeber he who dies with the most toys wins!
