I'll be taking my ridge runner out on it's maiden hang this weekend, and wanted to have an UQ of some kind even though the temps overnight will be in the 60's. I'm a warm sleeper, but if there's enough breeze, it might get chilly and besides, having options when car camping is never a bad idea.
Looking around, I liked the idea of using a poncho liner, and with an Army Surplus store just down the road, it was a cheap way to break into the DIY underquilt scene. When fall get's here I'll probably try my hand at a IX UQ or even do a PL IX UQ..
Anyway, dejoha's awesome tutorial on making a DIY no-sew PLUQ had all the information I needed, however with the shape of the Ridge Runner, I didn't think the way he did it would work for my application.
Not finding any other information on the forum, I decided to venture off into uncharted territory and make a PL Lynx Clone. Based off the picture of the Lynx on the Warbonnet website, I realized that folding the poncho liner the other way, would give me just enough width to cover the bottom of the hammock from edge to edge, and all I needed to do was to sew on 4 triangles of fabric to each side to allow the quilt to attach just like the Lynx does in Brandon's video.
Here's the final product:
As you can see, the poncho was simply folded lengthwise, and the ends cut to be symmetrical, but still curved. Cutting the ends flat would match the hammock, but I didn't see the need to waste material.
Each end has two triangular pieces of ripstop nylon added to it. This is made by cutting two pieces, and sewing them right side down to the side of the poncho liner.
The triangles, and loops are sized so that when the quilt is hanging slack, there is about a 1-2" air gap between the quilt and the bottom of the hammock.
The perimeter then had 1.5" grosgrain ribbon sewn between each loop, creating channels that I ran paracord through. I'm going to replace this with 1/16" shock cord once it comes in, but for now this lets me take in the slack and bring the quilt up against the hammock.
Here are some shots of it attached to the hammock:
The curved ends of the quilt allow it to come up on the head and foot end of the hammock and prevent any air from blowing between the quilt and the hammock when the top and bottom are synched.
