This inexpensive cello isn’t worth opening up for a full internal repair, but the double bassbar crack can still be stabilized effectively from the outside. By using a carefully shaped external mold, controlled clamping, and targeted gluing, the crack can be secured cleanly and safely—restoring structural support without removing the top or performing a major restoration. - Create Outside Mold: Make an exterior mold that matches the top’s curvature.
- Dry-Run Clamping: Set up the full clamping sequence first to ensure proper alignment.
- Glue the Upper Crack: Carefully work glue into only the top crack, the other lower crack will be glued later.
- Position the Mold: Place the outside mold onto the top to support the repair.
- Apply Band Clamps: Use band clamps to draw the crack together evenly.
- Flatten the Crack: Use the mold and additional clamps to level and flatten the repaired area.
- Tighten Clamps Fully: Finish tightening the band clamps for a secure hold.
- Dry for 24 Hours: Allow the repair to dry for one full day before removing all clamps.
