Catenary Arch Stained Glass Seed Cathedral

Construct the main structural frame using precise jig-cut wooden ribs bent into a perfect catenary curve. This architectural shape provides structural integrity while mimicking the elegant silhouettes found in classic cathedral arches.

Rabbet the inner edges of the wooden frame to accommodate custom-fit, UV-resistant colored acrylic sheets. These panels replace traditional glass, creating a stained-glass effect that invites light to dance within the feeding chamber.

Install a removable central cedar tray that sits slightly above the base for drainage and easy seed replenishment. The tray is held in place with hidden dowels, ensuring the aesthetic of the structure remains clean and uninterrupted.

Finish the exterior with a weather-resistant marine-grade spar varnish to protect the wood grain. Finally, mount a copper roof cap at the peak to keep seeds dry and add a metallic contrast to the vibrant colorful panels.
