Vintage Patinated Copper Diving Suit Air Pump Seed Bellows

Construct the main housing from reclaimed white oak to mimic the wooden aesthetic of antique maritime equipment. Apply a dark walnut stain and multiple layers of exterior-grade spar urethane to ensure longevity against the elements.

Fashion the external intake nozzle and discharge chute from sheet copper, intentionally distressing the metal with a chemical patina solution. Secure the copper components to the wooden frame using matching decorative brass rivets for a cohesive industrial look.

Integrate a functional crank mechanism that drives an internal wooden paddle, which pushes a measured amount of birdseed into the exterior trough with each rotation. This mechanical interaction provides a playful way to control the feeding rate while adding a kinetic element to your garden.

Install a hinged top lid sealed with a rubber gasket to keep moisture out and ensure the interior seed chamber remains dry. Finish the piece with a hand-polished brass plaque and a heavy-duty mounting bracket for secure attachment to a cedar post.
