Should work. I'd consider maybe enlarging the mortise and gluing in =
properly sized new wood if the piano was worth it. If it is low budget, =
your idea might work fine. I would recommend using #407 Low-Density =
filler or their #410 Microlight filler. Best would be to paint the wood =
with unthickened epoxy and then use the filler mixed real thick - like =
peanut butter. I would experiment with a few junk keys. You need to have =
a technique so that you don't fill up the rest of the mortise with epoxy =
- so that the keypin doesn't end up bottoming out (I don't think the =
caul is deep enough). Also, install bushings in the repaired test key to =
make sure the glue sticks to the epoxy.
