Essential Tools and Materials

• French Horn Bell Stem Repair Kit: This kit usually includes a specialized tool for straightening the stem, a small hammer, and a selection of metal rods for supporting the stem during the repair process.

• Cleaning Cloth: A soft, lint-free cloth is necessary for cleaning the stem and removing any residual polish.

8. Reassembling the Horn: Once the stem is repaired, reassemble the French horn, ensuring the stem is securely attached to the bell and the main body.
