Astro-Navigator Celestial Sextant Seed-Tracker

Construct the main frame using solid mahogany, steam-bending the primary arc to mimic the graduated scale of a classic navigation instrument. Ensure the wood is sealed with marine-grade spar varnish to withstand harsh outdoor elements.

Install a central pivot mechanism crafted from polished brass that allows the entire seed hopper to tilt and lock at specific angles. This feature creates a unique aesthetic while allowing for easy cleaning and refilling of the central seed chamber.

Create the hopper chamber from clear polycarbonate sheets, framed within the brass-accented wood frame for a view of the seed level. Incorporate a stainless steel mesh bottom to promote drainage and prevent seed spoilage during rainy weather.

Mount the finished instrument onto a sturdy cedar post using a weighted base to maintain stability in high winds. Add a small etched brass plaque to the front to finalize the vintage scientific instrument appearance.
