Re: Lag screws vs everything else...

Vote here for 12" Spax lag bolts. Big aggressive thread last 5" or so. I personally don't think a typical failure point (yurt; tent; shade structure) is going to be pulling that out of the ground. Nor is it going to be a reasonably strong cord (say, 500# milspec paracord using an ordinary trucker's ...

Re: Stretched hexayurt: Internal frame a good idea?

We were 8:20 and K.
And nothing fancy.
Not to mention our shade structure was not worth a crap, and a couple top supports broke in the wind.

Re: Stretched hexayurt: Internal frame a good idea?

DSC00667 (Small).JPG View from inside. Notice I decided the side rafters were superfluous, and simply used a vertical stud in order to have something to anchor the yurt to the ground, and support the sidewall against the wind. I did not separately tie down the roof in any way, assuming the tension ...

While we didn't get any horrible winds, no issues w/ the breezes we did have--esp Friday into Sat. Very spacious. 20x14, w/ 8 ft ceilings....

Finding one's fellow posters: How?

How does one find one's fellow ePlaya posters at BM? If my (stretched, internally-braced) yurt works out, I'd like to show it off. If it doesn't :( I never even went. But if it does, how do I bring supporters and skeptics by? And how do I find others to see what they did, so I can steal their ideas ...

Disconnect battery from solar setup to use ac charger?

At BM this year I'll bring my simple solar setup for some LED lights. (125 Ah AGM battery; 100W solar panel; PWM 30 Amp charge controller w/ DC load output).

Re: Truncated tetrahedron yurt?

First, that isn't a Yurt. Well, but neither are those hexagonal, taped structures made of rigid polyisocyanurate insulation. Generally, a "yurt" is a more or less round dwelling, with a more or less conical roof, typically made with a structural skeleton supporting external coverings which keep out...

Re: Stretched hexayurt: Internal frame a good idea?

Hexayurts set up easily (as long as there is no wind), are strong and stable, and almost dust free. When you start talking about 2 x 4's, well, yes. You might as well just build walls and a roof and nail the panels on like you would insulating a house. The only thing I ask, is when you complete you...

Re: Stretched hexayurt: Internal frame a good idea?

I have no clue. To my way of thinking it is no longer a hexayurt, you're building an entirely new type of structure. Why not just construct a small home while you're at it? I did not realize the terminology is important to the issue at hand. I'm curious why you care about whether or not it's "stret...

Stretched hexayurt: Internal frame a good idea?

I am planning to build a stretched version of the H12 hexayurt using 4x8x1" polyisocyanurate panels. I plan to extend the walls 16" vertically using 1/3 of a 4x8 panel, and then stretch the whole thing by adding an extra 4' of length to two of the side panels. This would create an overall end to end...

Looks ok to me. Test it on a 2x4 with a predrilled 1/8" hole. That will re-create about what the hard underplaya is like. Thanks! If that's the case, the pull strength will be fine...I will be using an anchor every 4ft. But is the purpose of this test the inline strength, or to figure out how much ...

Re: How do wind-loaded yurts typically fail?

They fail typically due to people substituting materials or technique that are not proven on the playa. The may not adhere well enough, or tear, or the heat causes the adhesive to let go. Or they use narrower tape and wonder why it didn't have the strength in the wind. Or the rope are a point-load ...

Re: What is the evidence for taping ALL panel edges?

This entire thread is based on a lack of research by the thread creator. Camp Danger tape hinges are without question the most common example of hexayurt construction, and they do not pre-tape the ends where the tape hinges are used, because the tape hinge seals the edges anyway. A hexayurt with 6 ...

I can't tell you how many ideas and deviations that I have thought might be great.

I posed a few questions and got shot down on some of my ideas in there on making one that could fit inside a vehicle.

More precisely, it's the supply air that needs to be outside air. It does not matter where the physical unit is. In fact, if the unit is inside, the efficiency would improve b/c there is less heat gain from the sun for both the water and the rest of the components. Of course, if you are using a buck...
