Vintage Patinated Copper Orrey Planetarium Seed Feeder

Construct the central cedar mounting post with recessed tracks to house the rotational gear mechanism. This will allow the planetary rings to spin slowly, distributing seeds through small apertures.

Fabricate the copper orbital rings using annealed sheet metal, carefully bending them into concentric spheres. Each ring should feature tiny embossed engravings to represent celestial markings.

Assemble the seed distribution chambers which act as miniature suns at the center of the spheres. These chambers utilize weighted flaps that open only when the wind rotates the planetary arms.

Apply a specialized vinegar and salt patina treatment to all exposed copper surfaces for an aged finish. Finally, seal the wood with marine-grade spar varnish to protect the mechanical gears from weathering.
