Part 5/9:
Paul recounts the detailed steps he undertook, including melting the wax in a level pan to prevent uneven thickness, cooling it slowly to avoid stress cracks, and using clamps to match the shape of the wax surface with the copper plates. His process required repeatedly refining the technique—cutting plates to smaller diameters to prevent sparking, adjusting thicknesses, and ensuring the wax cooled properly to maintain integrity.
