Vintage Patinated Copper Phonograph Horn Seed Projector

Begin by turning a circular solid walnut base on a lathe to create a stable, weather-resistant foundation. Carve a recessed tray into the top surface to act as the primary seed landing zone.

Construct the main horn assembly using custom-shaped copper sheet segments soldered together to form a wide, flared acoustic bell. Apply a chemical patina solution to achieve an authentic aged green finish that contrasts beautifully with the dark walnut.

Fabricate an internal gravity-fed hopper using clear acrylic tubing hidden inside the neck of the copper horn. Ensure the alignment allows seeds to flow smoothly from the reservoir into the walnut base tray as birds visit.

Mount the horn onto a sturdy brass pivot arm attached to a vertical walnut support strut. Seal all exterior wood surfaces with a high-grade marine spar varnish to protect the feeder from harsh backyard weather conditions.
