## Notes

- A #9 wine cork is Ø24 × 44 mm; long corks for aged wines are Ø24 × 49 mm.
- Both files are plain Ø24 cylinders at those lengths.
- A cork compresses to about Ø21–22 mm in a bottle neck, so it seals a 22–23 mm opening.
- Drilled through on its axis, a cork makes a simple displacer-rod gland for a test-tube engine.
