Vintage Aeronautic Propeller Seed Spinner

Begin by crafting the central seed hopper using cedar slats to create a tapered teardrop shape reminiscent of vintage aircraft fuselages. Sand the edges smooth to ensure a sleek, aerodynamic profile that resists moisture.

Construct the dual-blade propeller using laminated birch plywood, carving a subtle airfoil shape into each blade to capture wind. Attach the propeller to a low-friction ball bearing assembly mounted to the front nose cone for smooth, effortless spinning.

Design the internal seed delivery mechanism using a gravity-fed baffle system that links the rotating shaft to a small auger at the base. As the propeller spins in the breeze, the auger slowly trickles birdseed onto the circular landing platform below.

Apply a marine-grade spar varnish to protect the natural wood grain and finish the details with brass hardware for an authentic early-twentieth-century aesthetic. Mount the entire assembly on a sturdy swivel bracket to ensure the propeller always faces the incoming wind.
