I have a couple of weight forward spinners that a guy gave me 30 years ago that he designed. IS there way I can take these walleye lures, press them into a ceramic, or plaster of paris or rubber mold out of some material, so I can pour lead into the mold and reproduce what that man did long ago? Does anyone have any experience making a mold like this? I searched the net, but did not see anything.

Thanks,
Bruce
