Hello! I'm new to this forum/owning a big green egg. I purchased a small used from a guy moving out of town. It's been working great and I'm already planning on saving up for a large! I have one problem with this used one. The daisy wheel/cast iron top is stuck on the egg. I'm not entirely sure what the best way is to get it off. I don't want to damage the egg! It works fine as it, but it would be nice to be able to removed it and put on the ceramic top.
