I get the picture a bit clearer now.
With some cord and a few rubberbands, I have prototyped an underquilt that won't get ripped at any rate and might work.
More in the morning, if I make it through the night. cold front coming here in florida. low in mid forties.
If I do live, I will take a picture or two to share this wonderful thing. <G>
back porch hanger for two week now.
Well, the jury is in and the underquilt failed.
I almost made it through the night, but somewhere around 5 AM, the overnight lows got here. 48 degrees was forecast. I don't know the actual.I awoke to the feeling of my *** freezing off. I bailed and went inside.
I have newfound respect for you 30 degree people. I've been down to high 30's on the ground, but hanging is another story.
I couldn't get a good picture the way the light is this afternoon. This one will have to do.The poncho liner , mounted with three ties (two corners and a middle) tied off to each end, witha big rubber band at one end worked okay. It hung loosely at the ends, but was close in the torso region where I got coldest.
The idea of stuffing the space underneath with insulation occured to me, but at 5 AM the flesh was weak (and tired).
I think the next step is a double layer hammock with the 24 inch pad in the space provided
I tried to post a picture, but it got lost. It was 96 Kb and jpeg format. Size limit said 3 meg
I wonder what happened.
Like I said earlier, poncho liners start to fail most folk beginning about 60 degrees and by about 50 for sure it is bail time....
FWIW, you got cold in the torso precisely because it was loose on the ends... Loose ends are an "open window" summer technique...Any warmth your body was generating was lost thru the dual chimneys on both ends.
Thanks for the tip, Pan.
Your advice was spot on. I'm a see for myself kind of guy, so I had to go there.
I'm going to sew on another layer and slip the pad in there.
Luckily, the material I made the original hammock out of was still available in the Walmart $1 bin.
By the way, I weighed the 4 yards I bought this time. It weighs about 18 oz and has 6.4 sq yards of material for 2.8 oz per yard. Kind of heavy, but the entire hammock, with two ply will weigh less than 2 lbs. So goes it in the bargain bin!! <G>
I may make an X pad (ala Sgt. Rock), if the single dad doesn't get the job done.
If I come back to an underquilt, I will sew it up to fit. (or---Gasp!!) buy one.
Thanks for all the help everyone.

Last night was in the 40's . I put my mat (Walmart Blue 24 in. ) inside the poncho liner underquilt. I rerigged my rubberbands and found some small bungees to get a tighter fit. I was comfortable with the Sportsman Guide lightweight bag and a bag liner used as blankets. I wore a sweat suit and socks.
Today,I converted my homemade hammock to a Zhammock. It is supposed to go down to around 40 degrees, with wind chill (feels like)near freezing . I'm using the mat, the chintzy underquilt and a 20 degree synthetic down bag. I will keep the SG light weight bag as a backup blanket.
Report follows tomorrow.
Ain't it fun to reinvent the wheel???
Things worked out well. Weather dot com says 41 degrees at 6 am.
I slept through the night with one pit stop. I was quite cosy., although, when a body part got off the mat and against the hammock, a cold spot developed.
I screwed up the quilt rigging so it hung down a lot. since I wasn't cold, I didn't try to improve the setup. There is room for improvement when needed.
The two layer hammock is a treat. The ability to move around is a welcome change. My thanks to Risk and Just jeff for the instructions on "how to".
Now that my gear is workable from the thermal point of view, it's time to look at packing and space. I need to see how small the hammock will stuff. and maybe add a ridge line for ease of setup.I know the hammock itself weighs about 36 ounces. plus zip ties and hanging rope. Lighter than any of my tents and pole free, which make packing easier on a motorcycle.
Have a good day
