I discovered today that Thayercraft, a fiberclass supplier, is selling 3.3oz/yard pure Spectra 1000 fabric (roughly equivalent to Dyneema sk65) on their website and on Ebay. That weight seems about right for a pack, and I thought some of the MYOG folks might be interested. It's only $20/yard (60" wide), which is amazingly cheap for pure UHMWPE fabric, but the minimum purchase is a ten-yard roll. I don't know the details of the weave.
I'm not associated with Thayercraft, I just saw the Ebay listing.Oct 12, 2011 at 9:17 pm #1789845
Hum, thats a big minimum purchase. Maybe some folks could buy a bunch and split it up. Anyone interested?Oct 12, 2011 at 10:51 pm #1789875

I'd be willing to go in on a buy.
I'd like about 3-5 yards or so

I'd like some if it can be sewn. I remember a little while back someone said that spectra had to have a backing to it to be sewn. I could be wrong.
If it can be, I'd definitely take some and would give some money for a group buy.
I also doubt that it has any waterproof layer. I emailed them about a sample.Oct 13, 2011 at 5:30 am #1789918
I think I'm down for about 2 yards if everythink looks okay. Yeah I remember something about sewing being tricky so it would be good to figure that out first. I was thinking a really rugged burn type pack out of this stuff would be really cool.Oct 13, 2011 at 6:43 am #1789942
Depending on the specs, I'd be in for 2-4 yards if someone sets up a group buy.Oct 13, 2011 at 8:25 am #1789985
I don't live too far away from Thayercraft so I gave them a call to see if I could stop by in person to check out the Spectra fabric some time. I was told that a visit would be fine; however, they weren't sure whether the material was suitable for sewing into outdoor equipment or if it was intended for laminatng with resin. They also mentioned that they had both 3.3 oz and 4.1 oz weight material. I'll keep the group posted of my findings.Oct 13, 2011 at 8:42 am #1789991
Hey ya'll according the Ryan Jordan this might not be such a good idea. Check out his response to the thread I started on "sewing spectra." Basically a normal home sewing machine probably won't work for this stuff.Oct 13, 2011 at 1:51 pm #1790149
Well I went over to Thayercraft this afternoon to look at the 3.3 oz and 4.0 oz Spectra fabric, and my initial impression was that it is intended for lamination. However, it was such nice fabric and the people there were so accomodating that I couldn't leave without a few yards to use on my next kayak building project. Below is a picture of the fabric I purchased.Oct 13, 2011 at 1:53 pm #1790151
So are you thinking this stuff isn't great for a pack (aside from the concerns Ryan already shared)?Oct 13, 2011 at 2:02 pm #1790158

Hmmm…that looks like the uncoated stuff which would be a disaster for a pack. It has to have the coating in order to be workable, so the fabric is stabilized, and water-resistant.Oct 13, 2011 at 2:05 pm #1790161
If you look at the Spectra I got and the material that Dan Mchale uses on his packs, you will see they are not the same. The Spectra I have is a much coarser weave and it will probably be good for reinforcing a boat when set in epoxy. So the short answer is that it might not be the right material for protecting the bottom of a pack. However, if you are looking for some hard to find Spectra fabric for lamination, this could be a good deal. Anyway, before spending any money why don't you just have Thayercraft send you a sample.Oct 13, 2011 at 2:22 pm #1790172
Ryan thanks for the help. That would have been a disaster to have $200 worth of useless fabric split up among us.
David, thanks for the sample info. Sounds like I'll pass on it right now.
