Video : The Making of a Cuben Fiber Karo Step Under-Quilt

[MarshLaw303]

Cuben quilts are the reason I went to KARO. Almost 1/3 the total baffle length keeps the taping and tape weight way down. I use single sided Mylar tape from quest as it is much stronger than the sail tape in peal. Single sided also allows narrower baffles and lower tape weight, but at a higher cost. Griz, I sew my edge seams which is much easier than taping or glueing, was wondering why you chose to bond? In a tq the side seams are under very minimal stress, maybe the UQ requires stronger sides.

excellent point!

Another excellent point, but to get the lower tape weight you have to cut the tape. The single-sided stuff I've used was 1" wide...do you cut that down the middle for 1/4" on the baffe and 1/4" on the shell? Or just narrow it, say to 3/4" and get no use from the residual..?

It was a point of honor, I was trying to limit any and all air acess to the quilt to be at the ends. Probably would be different if I were building these for sale, thread is a lot cheaper! Even if I had sewn the sides I still would bond the channel because that is under stress.

enjoyed your well thought out video.
I am always amused by the fast forwarding sections.
It puts some entertainment value in the learning curve.

I was thinking the 1" tape was lighter due to the lack of double sided adhesive but maybe I was wrong, if your tape is the same I have the adhesive is much thicker than on the mylar tape, once stuck though it is dangerous to try and reposition the Mylar tape, I ripped a few when testing it months ago.

Love the quilt, I am planning something similar for the site by spring

Wonder if you're looking at the double-sided stuff that questoutfitters sells. That is thick and heavy, owing to a layer that has adhesive on both sides. The 3M tape I'm using (similar but not identical to the tape that WV tested and SgtRock demonstrated in his tarp-making video) is sort of like a layer of rubber cement that has congealed a bit already. And, unlike the double-side stuff from questoutfitters, is largely transparent because of it.

The double sided tape I used was this http://www.sailrite.com/Spinnaker-Ba...treaming-Video

I got a bunch of rolls on advice from Steven Evans but the very poor peel strength made me nervous so I went back to my Mylar stuff

Not same as the stuff I've this, here, also from sailrite.
The resistance to peeling is definitely poor and if I were building quilts for sale like you I'd use something different. My stuff is more resilient to misapplication of the baffle edge though, I can lift it off and put it back down again properly without tearing. The "other" 3M stuff that WV has tested seems to be quite a bit better that way, but I didn't have any of that at the time I built the quilt.

[MarshLaw303]

I do like that it can be repositioned, a great feature. Ultimately if it works who cares which tape I justed added the one I use hopefully not out if line.

[MarshLaw303]

Also I never used the c3 past doing a peel test so I am not saying it won't last or anything like that, I just feel better with the other stuff. Single sided also works better for the way I build them

Very nice. I've been wondering about the use of cuben in an UQ for a while now. Thanks for showing the way.
