Actually, I'm willing to dispense with "inexpensive" for the time being, but I don't think we've achieved the other two yet in a form that works over a very wide temperature range. Besides, for me "perfect" must include "no fiddle-factor".
Simpleton? Pffft, ya right! Most excellent write up, thanks for sharing.
Grizz, a few q's.
You stated you used sil as the inner layer..
How does that perform as far as condensation is concerned.
This thread is obviously from the archives ('08) and sil has been, as of late, a no-no for breathabilty and condensation.
What say you?
Ambulo tua ambulo.
Fun to get a bump! Been a long time since I wrote so much in a posting.
So I'm reminded of some work I did early on in the DIY bridge hammock explosion of posts working with a model to craft a suspension curve to the particulars of a person's weight distribution. You get to the foundational specifics of what's going on in a suspension bridge, go after the assumptions of uniform weight load, tinker with the equations to allow for heterogeneous weight distribution, and voila! A personalized suspension curve. I even made a couple of hammocks using that...but as far as I could tell it didn't matter
So, you're right, even with a bridge hammock it would be better to do a little tucking on the inner body so that in the region of the butt there is a little more space when the body is cinched up. I haven't taken that one on yet.
In all this I've not experienced any problems with condensation that I've notices. Perhaps the fact that there's a layer of wicking nylon between me and the UQ helps. Perhaps the fact that what I wear to bed wicks also helps. I dunno, the way I do things, it's not been a problem.
As it happens I'm in the midst of making another UQ, this too has a non-breathable inner layer. Perhaps there's a "Grizz makes an UQ" video in the offing....

The "Search" function is your friend!
Grizz, thanks for the walkthrough. I'm part way through building my own and I've taken the liberty of creating a calculations page on Meteor's google doc page to ease the process for anyone else.
Users can enter their desired specifications (finished length, head width, foot width, # of baffles, baffle height & fill power) and it'll spit out a basic parts order list (yrd of cloth, oz of down, baffle material are), and measurements to cut. It also lists metric units for our non-american friends.
Feel free to add things I've forgot/haven't realized I need. (Line locks, shock cord...)
