Michael, Worked on a few projects "trying" to do the same thing. It is important to know if the keys are broken or has something else failed. I'd love to help but I'm just an architect so I suggest speaking with David Flarhaty at +1 (215) 234-8242 plus one other fella whose name slips my mind. I am on the road and can find the name when I get back to the computer. They have injected plaster to restore bond. I also forget exactly what they used but recall it is similar to wood glue (but not that simple).
