>When the glue won't let go under normal circumstances, it's usually a 
>synthetic glue.  Take a mixture of 1 part ammonia to 3 parts water, and 
>put just a few drops into the mortise.  Then put your bushing iron tip of 
>your soldering iron into the hole, and turn the key upside down.  This 
>will result in the solution falling onto the hot iron, and shooting into 
>the felt.  Greg tells me that while it is a bit messy, it will blast the 
>adhesive such that it will let go, and the felt will come out with ease.
