so, this is totally in the planning stages, i have a very faint idea of what i might do, but like i said, if i cant get the 4 corner bolts figured out, the rest wont happen either
(ill grab some pictures of the tree i have in mind shortly, plus a backup one)
so far, the rough, rough idea is a 10x10 platform, with a 6x6 house on one corner, leaving a 4 ft "porch" on 2 sides
as far as weight goes, i went online and looked up a 10x10 wood shed, with floor on the lowes website and the claim it weights 1041 pounds
this is with a larger roof and wider walls then i intend to build, but much thinner floor joist, so i think its a bit of a trade off, and the treehouse might come in at 1100 pounds
add a few kids and i think i want to be able to hold up 1500 pounds
according to the principles laid down by
@Cuda416 , i would want fasterners with a combined rating of 15.000 pounds
that would be 13 of those 3/4 lag bolts BUT everything i read online (and what i gathered from talking to my arborist buddy) tells me the lesser holes in the tree the beter
(people also seem to advise against drilling straight through and using a threaded rod)
so, i think id want to simply get a heavier rated mounting bolt
i found a vendor on ebay selling 1.25x12 lag bolts, im waiting to hear back from him what the sheer rating is
