<html> <blockquote type=cite cite> I method I've used is to tape the crack on the board surface, the tape needs to be tight across the crack and not concave.  Invert the piano and apply epoxy from the 'bottom'. This gives a level surface and you don't have to worry too much about shrinkage.

No clean up on the top side. Regards Roger </html>
