So I let it slip that I made a sil hammock before I had the pics up on the website...I'll probably add them this week, but until then I didn't want to hijack the other threads so I'll start one here.
I had lots of sil, and one panel was already cut to 11' by 65". I hemmed it all around, then added channels at the end to use cinches instead of whipping. Final dimensions are probably 64" wide and 10' 9" or so long.
I used random cord for the cinch b/c it's not supporting any weight...I still larkshead the support onto the hammock itself. I went with cinched ends mainly b/c sil is so slippery that I wanted more than a simple rolled hem to keep the support on.
I'm using BPL Air Core Plus for the suspension, and a 100" Spyderline ridgeline.
After laying in it, I realized that 100" isn't long enough for a ridgeline on an 11' hammock, so I just used a double sheetbend on the foot end to take up some space. Right now the extra is just hanging useless off the end, kinda like the tent in my garage. I'll probably end up cutting it and putting a cinch there.
I could just make a longer ridgeline, but this one is plenty comfortable right now, and a longer ridgeline means I'd need a longer tarp.
Since I cinched the ends instead of whipping, the sides are very saggy right now. So saggy that it's pretty easy for my legs to poke over the edge, and probably pretty easy to fall out of. Think of the Blackbird w/o the footbox to help keep your feet in the hammock. I'm deciding what I want to do about that...either sew darts in the edge above my feet, make a BB-style footbox, maybe even out of netting, etc. I actually have some other sneaky plans but I need to prototype them first b/c I'm not sure I can describe them until I play around a bit.
So what's it like laying on silnylon? First of all, I've spent several nights in the Crazy Crib, which is made from coated, non-breathable, waterproof fabric. I never had a condensation issue beyond a normal hammock, which surprised me. So now I think using a sil hammock might be a lighter way to make a warmer hammock, and it would keep body moisture from getting into the underquilt. So I made this one, and have laid in it for a few hours now but haven't slept in it yet. I can sorta feel a difference, but haven't been damp when I got up. The single exception is that once, since the sides are so flappy, I was using it as a pillow while laying on my stomach...so half of my face was flat on the sil. After about 15 minutes that way, I got up and my face was slightly damp. I think part of it was b/c I was breathing on it, too. I'll sleep in it sometime soon and give a more detailed report when I have more info.
It is much more slippery than other hammocks, though. I usually have my bare skin (shirtless and in shorts) when I'm in it right now, so that's not really an issue...but I wonder if it'll be hard to stay in a comfortable position if I'm wearing socks and long johns.
Haven't noticed any undue stretching of the 1.1 oz fabric yet, either. Not like the 1.1 oz DWR I used for another DIY hammock...the stretching on that one caused serious shoulder squeeze and was uncomfortable almost immediately.
Haven't weight it yet or taken any pics, but I'll definitely have that when I put it on the website. More to follow.
