Zimmerman piano with detached sharps

Zimmerman piano with sharps that come unglued. I find Araldite is the best for this job. I take the key out to do it properly so I wouldn't recommend a non piano technician to try it. Araldite glues anything to anything. As most sharps these days are made of plastic it's the perfect adhesive for gluing plastic to wood. I've never had one come off after being reglued.
