CD, I opened a Domestic. It was full of mud dauber nests. Those guys had gone through the pillar all the way to the faceplate. I spent serious time with and ice pick to try to get it emptied of nest material. It took lots of poking and shaking before I could get the balance wheel to move. I now have it so it can turn, but it isn't smooth or free yet. I'm thinking it may need to take an oii bath,
