slowly but ever so surely i’m making progress on The World’s Most Awesome Treehouse(s). i got a few of the 16′ joists up on the supports while almost nominating myself for a darwin award. today odin helped me attach more joist hangers to the 14′ 2x10s so we can quickly drop in the rest of the joists.
lots of folks are asking me about the how secure the platform will be. you can probably see the top of the four supports are bolted on to the 3/4″ threaded rod that runs through the trees. the bottom of the supports are attached to the trees with 3/4″x8″ lag bolts. the top of the supports which i think are called knee braces are made from 2×8″ treated lumber and angled boards are notched into the top and attached with 1/2″x6″ lag bolts. the joists in 16″ on center. somewhat surprisingly, everything is level and mostly square!
the supports are about 11′ off the ground and the joists add another foot, so the treehouse will be about 12′ off the ground when i built it on top of the platform.
i’m pretty impressed with the stability of the structure. hopefully, i’m just as impressed after all the joists are attached and the flooring is put up 🙂
( side note: the blue rope is part of the the most super awesomest tree swing. EVAR! )
