I've been plugging away on my 'mid project and got it far enough along to put it up this morning. I just hemmed the bottom edge and sewed on the line locks. Still have some more details to get done- something to tie the doors open, some extra guy outs, mid panel pull out, etc.
The best guy line I had on hand that would work in the line locks was para-cord. No ideal, but the rest of my z-line is too thin for the line locks to work. And this was my first time pitching a 'mid shelter- plus my hex shaped footprint, made it a bit of a learning experience.
My first attempt netted me less than satisfactory results. I went with this unconventional design because of its economy of fabric and amount of sewing, but how well it would pitch was at risk. So, after playing with the tension on the guy lines, I finally gave up and went inside to eat breakfast. I was a bit on the upset side, since it was about $75 spent and a great many hours of time spent, for something I'm just going to want to re-do. Doing over gets closer to the "it would have been cheaper to just buy a duomid" point.
So, a bowl of raisin bran later, and time to reflect on where the fabric was the most slack I realized my center pole was too short. So, I went scrounging around in the garage hoping to find some 1/2" pvc pipe. No luck- but I did fine some 1/2" sprinkler risers. I went out, loosened all the guy lines, pulled out the center pole, stuck the makeshift pole-jack in place and re-tensioned it with much more satisfactory results. I still think with a bit more practice I will be able to get an even tighter pitch.
One thing I did not expect, though I should have, was the amount of tension across the zipper. I place a side release buckle along the bottom hem like MLD does, but since it's a hex shape, the area of greatest tension is about 12" up from the bottom hem. I feel like I wasted a ton of money on the waterproof zipper. The tension is enough to make it possible to see daylight through the zipper teeth. I may end up placing a 2nd side release buckle there...
One thing I didn't like that much with 'mid tents is how open they are to the elements when the door is open. I saw a few ideas thrown around on the forums so I thought to give one of them a try. So, I sewed in a couple extra flaps of fabric and another zipper (more weight!), so with a third pole it can open up like this-
In this mode it is absolutely cavernous. I originally wanted to use separating zippers so the awning panel would be removable, but I could not find separating zippers long enough. The awning is much flatter than I expected. I maybe could give it a bit more slope with some adjusting of the guy lines. What I don't want to happen is for water to pool up there, and then leak through the zipper.
peak reinforcement and "pole jack"
I bonded the guy out reinforcements and then sewed them. I'm pretty happy with the results.
I hope the images show up properly- I'm trying to imbed them from my picasa album. If that doesn't work, I'll have to download all the photos and attach them the hard way (vbulletin for the win). Too bad these forums don't have a preview post option... :(
eidt- only two of the pics worked.. What is the deal with that?
