Construct the dual-chamber base frame using walnut to house the seed reservoirs, ensuring the wood is sealed against moisture. Assemble the internal mechanisms that resemble the mercury-tube housing found on antique psychrometers.

Fabricate the protective exterior canopy using sheet copper, then apply a chemical patina treatment to achieve a deep, aged aesthetic. Carefully rivet the copper panels to the top, allowing for a slight overhang to protect the seed ports from rain.

Install the brass scale plating on the front panel, laser-engraved with decorative meteorological-style markings. These plates serve as the visual aesthetic while also framing the viewing windows for monitoring seed levels.

Finalize the assembly by integrating the antique-style hanging hardware and polished brass finials. Apply a high-quality marine spar varnish to the wood for long-term outdoor durability while preserving the vintage patina appearance.
