I have an 1860 Pietta. The wedge is a monster to remove. I tore up a wooden dowel trying, and the last two times I've removed it I used a rubber mallet. When I do get it apart, the cylinder will move up and down the base pin, but it won't come off without some serious force. It gets really stuck when the end of the base pin is even with the front of the cylinder. I can get it off, I just have to smack on it for a bit. It looks like it might be ever so slightly bent. Is there a way to straighten it out? It probably won't take much. I don't want to beat on the base pin and booger it up. Any ideas?
