This flute came in with the A Key bent backwards so far, the foot caught on the lip of the tone hole, and subsequently broke, damaging the tone hole lip as well.

Left Pic – Damage to the rear of the A tone hole
Right Pic – A better viewpoint of the damage

Left Pic – After rolling the lip back over, I still have a high spot at the rear of the tone hole
Right Pic – Using a small tone hole file, I lower the high spot

Left Pic – High spot gone
Right Pic – Now to fix the broken foot on the A Key

Left Pic – Ready for brazing
Right Pic – All brazed, ready for cleanup

All fixed and ready to go
