Karo Underquilt Adventure

[samiam2714]

I finished my under quilt a while ago and now I am waiting for the extra down I needed for the top quilt. I also must not I made this huge because I intended to use it only for Jeep camping and never backpacking. Right now the quilt is too hot to try in the house so I will report on the warmth when I get out next. I imagine it will go down to 0*

I marked the baffles out using a grease pencil and the long piece of angle Aluminum. for the edges and a large framing square for the individual baffles. The dimensions for this are.
Under quilt
(80x45x3.25)/800 = 14.62 (actual down used - 24oz.)

Black and Grey
Cut widths

Inside
47" wide
82" long

Out side

60"wide
88.5"long

Baffles
26' 3.25 wide
3.75" cut width

Splash guard
85"x50"
L
Cut length
87"
Cut width
52"

Outside fabric laid out on kitchen floor.


Baffles Sewn on




The top, bottom and sides sewn ready for stuffing
For the side I simply cut the bottom out wider and longer and sewed them up and put a seam in so it would be more rigid






Tent in the living room, vacuum inside with no-seeum on the end, ready for the mess.








I didn't loose any down with the vacuum like this I could just pick the down off the end of the vacuum and stick in back in the quilt. As I got to the end I pinned the sides in. On the top quilt when I fill it I will use ductape and close it off more before I start stuffing.

And Finished, This took me in total minus wait time, 3 days to complete.










Top quilt next I am only doing 2" baffles on that.

All but a couple of your images have a "403 Forbidden" error and are not shown. The few that are shown are HUGE!

Great stuff! Im sure you will be happy as anything in that. Nice and warm as well

Karo step baffles for the underquilts are awesome. So much down movement control to help with them personal cold spots.

Real nice work.....
can't wait to see the next one

[Lonely Raven]

That looks great!

What material did you use, and where'd ya get it?

[samiam2714]

I used 1.9 ripstop from quest and the noseeum from them as well I made sure when I cut it the stretch direction would be the short direction not the long direct so it didn't stretch as I stitched. Since I figured the bottom material was so slippery.

If I did it again I would use 1.1 and bias tape for the channel instead of 1.9 but I figured I would go for durability. Since it's for car camping weight didn't matter.

I don't know how I missed this post. Nice work! You'll be warm this winter.
You and I were building around the same time. I thought mine was big, yours
is a bit on the huge size as well What did your weight come in at with cordage and all?
I've been using mine indoors a bit with the ends draped open for temp control
and really enjoy it, can't wait for the cold weather and the outdoor tests.
Have you started your topquilt? Are you going to repeat the karo step?
Enjoy it, looks great

Maybe I've missed it before so, sorry if this is a dumb question. Are any of the "steps" closed? or are they all open to the quilt? ie Do you only have to do one down-dump?

If so, seems like it'd be a real pain to distribute the down the first time, but after that, pretty cool.

Thanks.
