Vintage Patinated Copper Diving Bell Seed Chamber

Construct the main body using bent copper sheets fashioned into a heavy-duty spherical dome. Use a traditional planishing hammer to create the authentic hand-beaten texture of a classic deep-sea diving vessel.

Incorporate a circular observation window using thick, clear acrylic framed by brass hardware. This allows the birds to approach the feeder while offering a fascinating visual focal point for observers.

Attach a custom internal gravity-fed hopper system to ensure seeds are dispensed evenly at the bottom rim. The design mimics the pressure-sealed air intakes found on historical submersibles.

Finish the exterior with a controlled oxidizing solution to achieve a rich, aged teal patina. Seal the metal with a clear outdoor lacquer to protect the finish while maintaining the weathered steampunk aesthetic.
