Vintage Accordion Bellows Seed Expander

Construct the upper and lower maple housing units with intricate miter joints to serve as the structural anchor. Install a central vertical rod that allows the middle section to slide up and down securely.

Create the expandable bellows using thin, flexible cedar slats connected by weather-resistant fabric hinges. These folds naturally collapse or extend to adjust the internal seed capacity based on current bird traffic.

Incorporate small brass decorative keys along the front panel to simulate the classic aesthetic of an old-world instrument. Use a food-safe sealant on the internal gravity-fed hopper to ensure longevity and hygiene.

Apply a final coat of marine-grade spar varnish to protect the wood from moisture while highlighting the natural grain. Attach a sturdy copper handle to the top for easy hanging and replenishment of your favorite bird seed mix.
