Bluebird House: latest best

These are in-process, the final roofing shows up down the blog; but this shows the series of six with all the basics covered. The dark color is a flame finish, an idea originated in Japan called Yakisugi (or Shou Sugi Ban). It takes about 20 minutes to “paint” the burn for each house with a little butane torch. This seals the wood making it waterproof, bugproof, fireproof, and UV tough. Bluebirds often nest in old woodpecker nest-holes carved in forests after big fires; so they should feel right at home in a flame charred house. This is a modified version of the “Carl Little” design from the National Bluebird Society, http://www.nabluebirdsociety.org/PDF/Carl%20Little%20Bluebird%20Box.pdf Cost per house is $14.00
Bottom floor is seated 1.25 inches up, with a cut-line 3/8 inches up- these both mitigate water. And the bottom tie-down eyehook.
The roof slopes at 20 degrees with its own underside cut-line to drop back-flow water. The lines on the bird box are grab lines for the birds, antithetical to the cliche’ perch. The smooth face keeps other birds from hassling them, and the slot entrance tucked under the angled roof deters other birds and predators as well.
The wall of the house drops open for clean out, and peeking in for brood checkups. The flat peak of the door is mirrored on the opposite wall, providing cross-ventilation in conjunction with the slot opening.
More airflow and water drainage is at the floor, with the points of the edges trimmed back. Another essential element is the climbing ladder, allowing the chicks to exit.
A secondary clean floor of cedar sits atop the house floor, with a thermal break between them of aluminum sandwich insulation.
Here the floor panels are stacked.
At top and centered in the wood slat is a threaded insert for the door lock.
This wingnut/thumbscrew bolts the door closed. Below and to the R is an eyehook, mirrored on the opposite side, (and the one already noted on the bottom) for anchoring wire that affixes the house to fenceposts.
Next is a thermal break of aluminum sandwich insulation (at L), then covered in cedar panel as weatherproof shingles (R).
The metal plates cover a little gap I added to the entrances, thinking I had made the entrances too narrow. Turns out they were fine, and the gaps needed covered. The covers are angle corners pounded flat.
Last Friday I built out this storage sled for/with an artist friend to hold seven 4×8 foot panels of a big mural. This will fit into the back of a moving truck and strap down, then the art goes in place for a 500 mile drive to Denver, where the art will then be unloaded from the sled by a specialty company for fine-art international air-freight to London, who will make the real crating.
The artist’s plan prior to this was stack them on the floor with blankets between them, I proposed that this would keep them safer: upright, separated, padded (pink gasket foam), and tied down via the frame rather than the artwork.
