The tailpin had broken in the dowel stick

This instrument put up a fight. The screw that fits in the end of the dowel stick, holding that end to the pot, had broken. So I had to drill down to it, then saw across it so as to make a slot in the end of the broken piece. This let me use a thin screwdriver to unscrew it. Then I could plug the whole hole with a piece of dowel, and fill in the slot with fine sawdust and glue.
