Im trying to pour a do it screw loc worm nose jig and am having a couple intermittent issues. First one is sometimes the jig comes out looking good but the hook is loose. Second is sometimes the lead gets into the coil and is not easy to get out without ruining the coil. Can I use a blow torch to melt the lead out of the coil w/out ruining the rest of jig? Both problems dont happen all of the time seems to be no rhyme or reason to it. Using pure lead that i fluxed with compound, a bottom pour spout pot, do it mold and lead seems to be a correct working temp as my other tube jig heads came out great. Also pot is full and mold warm. Im not pulling the jigs out by the hook and when mold closes there is no gap in the seam as all of the components in the mold are correct size and placed in where they need to be. Any help is greatly appreciated.
