couldnt see that 2x on the stairs, that will work,you mentioned in one of the post's a lot of adults, i could see that coming down with 20 college kids up there, i would overbuild for that reasonQuote from Bradson Petrog:
Hi Ammo,
The structure is streamlined to diminish excess weight where ever is it feasible. 24 inches on center is both allowable and sufficient to support the flooring substrate and decking.
If you look closely you will see that I have used a combination of 2x6 and 2x8 floor joists. I've even added some 2x4 supports within for extra strength as you can se beneath the lookout chimney. There are three interior 2x8 joists, as well as the outer band joists all being 2x8.
The overall length of the front 2x8 band joist is 12 feet, but the longest load span of any 2x8 joist is only 8.5 feet, due to the cantilever system. This is well within the limits of the 2x8's span/load capacity. The three 2x6 joists you see beneath the building's interior, are spanning only 6.5 feet. Again this is more than sufficient in regards to the span/load capacity of the boards.
The joists beneath the left side deck are actually spaced 23 inches apart on center. The reason for any of the unconventional joist spacing is because of the need to find key measurements that are a happy medium between the two trees and also to conform with the conventional lengths of framing/sheathing members.
That's some eye you have there to be able to see the joist spacing on the left is one inch under 24...very impressed
While there are 13 steps to the landing, the stringers themselves have only 12 steps. The stringers also have a 2x4 fused with glue and screws to the interior side of each stringer, where the tread meets the deepest part of the notch. This adds significant strength to the load capacity of the stringers. So with the added strength of the sistered 2x4's along with the narrow width of the stairs, a 3rd stringer isn't needed.

Hi Duecy,
That is a nice thought, but like someone else on here pointed out, I'm not sure that it would be a likely achievement. Just too many variables to go big time with it, I think.
Sure they can be installed at jungle canopy level, it would really just depend on the trees themselves how high you could go.
Not sure what Jungle penetrator is but, sounds like a good description of a buddy of mine. lol. I don't see a problem with a repelling kit though.
Yeah, I've put a strict limit of 6-8 adults on this and we've had that many up there with no problems, and there's really not much room for more than that. I plan on adding 2-4 more braces to the under side later when we come back in to pour concrete below- probably in the spring. That 'you never know' factor does sit in the back of my mind.
You sound like you do some building yourself. Any particular scope that you have the most experience with, or are you one of us jack of all trades types?

Thanks for looking, and please feel free to comment. [/B]
Whoa! My son would be so jealous. Hell I'm jealous. lol.
How high is that bad boy? That's gotta be 30-40 feet at least.
edit: How does that thing even stay up? it looks like it's just floating up there
Hi Hoof,
Thanks, my kid and his cousins/friends love it too. Hell, we all do for that matter.
Yeah it's about 37-38 feet to the top of the tower. A little over 20 feet at the deck.
It has 5 key supports. If you look closely you'll see two 6.5 in round fir braces. The base of the braces are slightly notched/bolted into the tree's trunk, then sealed tight with several ounces of urethane glue.
The top of the braces are double notched to the joists in a way that locks in, and allows gravity to form the best connection. It's also steel reinforced with bolts and urethane glue.
Nice! I guess I needed my glasses. What about that outside corner of what looks like a diving board platform sticking out. I think it's where the stairs come up to, but they are not in yet. What is holding it up, and How much weight can it support?
It's hard to see, but if you look just above the ladder you can see there is another(short) 6in round fir brace holding the joist that connects to the outside bandboard you are referring to. The entire design rests upon the laurels of gravity and the cantilever system. That outside corner you are referring to will easily hold several thousand pounds.
The strongest points of the house are of course the spots where the joists sit directly above the tree trunks. These spots will easily hold tens of thousands of pounds, and realistically over a hundred thousand pounds at the very strongest points.
The spots directly over where the braces connect to the joists will easily hold twenty thousand pounds each. The weakest parts of the floor joist system will easily hold several thousand pounds or more in any given spot. Over all, you could park a Mac truck up there.
It's actually designed to give it that floating up in the trees look, so I appreciate your comments.

That's friggin cool! I thought it was a real chimney from the other pics. Now I see it's just an illusion, but a cool illusion. Is there a ladder or stairs inside that go to the top?
inside there is a door opening to the chimney tower. then a tree inside that takes you to the top.
