Construct the main pressure-resistant chamber using bent cedar slats reinforced with circular plywood ribs. Ensure the internal seed hopper is tapered to funnel grains toward the bottom-mounted feeding tray.

Fabricate the outer shell by hand-shaping copper flashing to fit the curvature of the bell. Apply a chemical patina solution to create an authentic, oxidized maritime aesthetic.

Install circular brass porthole rims fitted with clear acrylic viewing windows. These allow observers to check seed levels while providing a vintage nautical aesthetic.

Attach a heavy-duty chain and a top-mounted air-vent detail to complete the silhouette. Seal all wooden components with marine-grade spar varnish to withstand the outdoor elements.
