Aeronautical Aviary Propeller-Driven Seed Spinner

Construct the central hopper using high-grade cedar, carving an aerodynamic teardrop shape to reduce wind resistance. Ensure the internal funnel is precisely angled to direct seeds toward the outer release ports.

Fabricate the twin propeller blades from stained mahogany, shaping them with a subtle airfoil profile to capture minimal wind currents. Attach these to a low-friction ball bearing assembly mounted to the primary drive shaft.

Integrate a brass-toothed gear mechanism inside the feeder housing that connects the main shaft to a rotating feed-gate. As the propeller spins, the gear rhythmically opens and closes the seed ports, creating a controlled dispense rate.

Finish the assembly with a marine-grade varnish to protect the wood from harsh outdoor weather. Mount the unit on a decorative iron stand that allows for full 360-degree rotation, ensuring the propeller always faces into the prevailing wind.
