The creator builds an "impossible dovetail" cutting board with a hidden sliding dovetail joint. After experimenting and testing with smaller prototypes, they successfully create a full-scale version of the joint. The board features three dovetail joints that can be slid into place, creating a seamless and "impossible" connection. With patience and persistence, the creator overcomes challenges and achieves a precise fit, showcasing the final product in a beautiful and functional cutting board.
Here are the key facts extracted from the text:
1. The project is to build an "impossible dovetail" cutting board with locking joints on all four sides.
2. The creator has experience making cutting boards as a side hustle.
3. They are using black walnut wood for the project.
4. They are using a CNC machine (X-Carve from Inventables) for the cutting process.
5. They are using Fusion 360 software for 3D modeling and designing the cutting paths.
6. The creator is new to cutting in three dimensions and had to learn how to use the CNC machine for this project.
7. They had to calibrate the machine for better accuracy and adjust the settings to get the desired fit.
8. The creator made a test cut to ensure the fit was correct and made adjustments as needed.
9. They are using a waterproof glue to assemble the cutting board.
10. The cutting board has an end-grain design with a walnut top and cherry bottom.
11. The creator added magnets to hold the cutting board together.
12. The impossible dovetail joint has three dovetail pieces per side.
13. The creator used poplar strips to support the cutting board during the machining process.
14. They had to relieve the edges to reduce friction and allow the cutting board to fit together properly.
15. The creator spent several hours sanding the cutting board to achieve a smooth fit.
16. The final product has a lot of friction, but the creator is happy with the result.
17. The creator plans to add a finish and oil to the cutting board.
