This is my first attempt at building a wooden door ! Its built of Sapele 1/4 sawn 1 3/4 inch thick , the top and bottom stile & rails have a 3 inch square mortise & tenon with two through mortise & tenons on each stile & rail using black walnut for accent. The top and bottom panel l used laminated glass 1/4” on the front of the door followed by black walnut over lapped lattice , to that l added blue flash antique glass & a pebble clear glass . The middle panel is african mahogany with black walnut inlays protruding by 3/8 ” . l finished it with tung oil 2 coats & 2 coats of wax . l installed a full glass panel storm door in front of it to protect it from the winter weather . So far its worked out well.
