In which I use Physics, and possess Insanity.

I am slightly insane.

I like being insane, so it's okay, but let me tell you all about my insanity.

I mentioned at the beginning of the month that I was thinking about making a hammock for sleepage. Well, I did it.
It went through a couple iterations, but I did end up sleeping in it last night.

I had to create a stand, because I didn't want to put holes in my walls (yay renting!), and I wanted a simple stand that didn't take too much work and could be dismantled without too much effort. I decided that the stand variously known as the TurtleDog or Tripod stand was the most practical. The second iteration regressed to the vanilla Turtlelady stand, because the Olddog variation collapsed on top of me (ow...).

Let me explain that last paragraph...
A contributor on hammockforums.net, known as Turtlelady, came up with a dual-tripod+suspended-crossbar stand made of bamboo.
The physics of this is that a tripod is very sturdy, and if one were to suspend something from the centre joint of a tripod, between the legs, this is a very stable place to hang. If you had one tripod and a bat-hammock (all corners hang from a single point, and yes, this is a thing), you'd be good to go.
However, an ordinary hammock (especially a loaded one) pulls inwards towards itself from either end, so even if you were to hang both ends of the hammock from two tripods, they would collapse because it's not a direct downward pull.
Hence the suspended crossbar.
Hang each end of the crossbar from the centre joints of the two tripods, and each end of the hammock from the ends of the crossbar. The crossbar takes the horizontal inward force from the loaded hammock, and the tripods take the vertical force. At that point it becomes very sturdy indeed.
Turtlelady's stand was based on the three poles in each tripod being lashed together with rope, and another rope farther down the legs to keep them from splaying out and collapsing downwards.
Another contributor known as Olddog made a variation on the Turtlelady stand, where the inside two legs of each tripod are screwed onto one half of a gate hinge, and the outside leg is on the other half of the hinge. Hence why it got called the TurtleDog stand - a little bit from each contributor. The Olddog version is little more industrial-looking, and (I thought) a little more sturdy.

It seems I didn't get strong enough hinges, is the short version; I set it up for the first time last night, and everything went well for several hours, until the legs twisted around and bent the hinges and the whole lot came down, at about 9.15pm last night. I'm just glad nothing broke.

Of course I had already adjusted my bedroom to make room for this thing, including standing my mattress/boxspring up against the wall, and I, being the stubborn, do-it-all-by-my-own-fucking-self, pigheaded chick that I am, was determined that I would not put my bed back down for love nor money. No, the hammock and stand would do what I wanted, even if I was up til 11.00 to do it.

Happily, I had picked up a package of 100m or so of poly cord from Canadian Tire just in case (in case of what? I wasn't sure, but now I know!), so I dismantled the tripods and hinges and used the cord to lash the hell out of those poles. I also took the screws from the hinges and screwed down another piece of poly cord to keep the legs from splaying out too far.
I even tried to put my small knowledge of physics to use, and set up the two tripods to twist in opposite directions (because when you use lashing, the legs have to twist past each other in order to open up) so that both tripods won't overtwist in one direction and collapse, which is partially what happened with the hinges - I looked at them after they came down, and they'd both twisted the same way. It works in my head, I'm not sure if it's real physics or just Lizzi-brain-physics, but I'll go with it. Any real physicists want to chime in on this? For science!?

Anyways, after that, I got it set up with no more issues, all was well, and I slept in the damn thing, and I was even in bed a little early.

The only thing I didn't like was that it was a little colder than usual, so I didn't sleep as well as I could have, but I have an idea to fix that too. I'll see how it goes tonight.

So that's it. Toodles all.
