I am having a hard time removing the pull pin from my Egg Sinkers once casted. Is there some sort of trick?

If the sinkers are allowed to cool removing the pin can be difficult if not impossible. The pull pin should be oiled slightly or smoked with candle soot before starting and occasionally during the pouring session. An oily rag works well. Insert the rod from the hinge end of the mold. After the lead is poured into the cavities, the pull pin should be removed immediately using a twisting motion. Failure to oil or smoke the pin before the first pour, or allowing the lead to cool in the mold will make withdrawal of the pin difficult.
