I just finished grinding 10 lbs of goose breasts with pork fat for sausage. When I finished I cannot get the ring cap off of the Chute of the grinder (altra meat grinder). I have tried using a wrench and a bunch of other methods to get the cap off. I believe that some fat/meat has gotten stuck along the threads causing it not to twist off. Any suggestions as to how to break down what is keeping it stuff so it will come loose? I have tried soaking it in hot water, WD40, a wrench and other methods
