Construct the central vertical spindle and weighted base using brass-accented hardwoods to ensure smooth rotational movement. This serves as the planetary axis that will allow the feeder to spin freely on a low-friction ball bearing.

Craft the planetary seed-troughs from bent-wood laminations, each representing a distinct planet suspended on adjustable brass rods. Seal the wood with marine-grade spar varnish to withstand exterior orbital conditions while showcasing the natural grain.

Install the gravity-fed internal reservoir within the central sun-core, utilizing a clear acrylic cylinder to monitor seed levels. Design the discharge ports to release grain into the orbiting troughs through a calibrated mechanical escapement.

Balance the entire system by adjusting the counterweights on the secondary armatures to ensure the structure rotates gently in the wind. Final assembly includes mounting custom copper finials at the end of each arm to deter squirrels while adding aesthetic celestial flair.
