Yesterday I received an email from a cimbalom player who wanted help to fix a few loose tuning pins. Although I am not familiar with cimbalom I suggested that he could try either 1) Cutting a piece of rough cardboard to use as a shim, rolling it up, putting it in the pin hole and reinserting the pin. Or 2) removing the pins and squirting superglue into the hole and reinserting the pin before the glue dries. He tried option 1 with the cardboard shim and said it worked and thanked me for the assistance. http://forum.pianoworld.com/ubbthrea...board-fix.html
