2. **Assemble the Magnet Disc:**
- Arrange the neodymium magnets around the rim of a disc made from MDF. Ensure every second magnet has its North Pole facing upwards.
- Drill holes into the MDF sheet slightly larger than each magnet to accommodate a waterproof seal.
- Use varnish to soak the MDF, making it damp-resistant.
- Carefully insert the magnets into each hole. Be cautious as they tend to stick together and are very strong.
- Apply resin to secure the magnets permanently in place. Ensure each magnet is held down until the resin sets.
