Where can I get some 1-1.25mm spectra….a lot of it?

I have a list of lines here, though I don't cover ones that small. I don't like tying knots with lines that small.

You can get 50 pound test (and lighter weights too) Spectra fishing line from Sports Authority. It works well as thread for hand-sewing.

Check out mojosgear.com (no relation), they look to have a pretty decent assortment of dyneema cordage. 0.8mm, 1mm, and 1.25mm unsheathed dyneema line are all available. 1.5mm is the smallest listed size they have available sheathed, although I suspect the 60-80kg rated stuff w/ dyneema core is probably between 1-1.25mm:

Note the minimum order requirement of 100 meters (and it's not mix and match, either).

Disclaimer: I have no idea if these guys are legit or not. Can't find them on reseller ratings or BBB…

I would avoid the fishing line. I bought some on eBay that claims to be pure dyneema/spectra and it appears to not be. The cord has far more stretch then spectra/dyneema normally does and frankly it's just poor stuff.

I have had good luck buying spectra cordage on eBay. I bought a spool (ie. 200-300 feet) of 1/16" stuff (1.6mm) and it was excellent. Try searching for 'speargun spectra' on eBay. I used my cordage for everything from bear bagging to cinch cords. It was amazing how many uses I was able to find and how much weight I saved. That stuff was around 14g (0.5oz) for 50 feet which is excellent. Unfortunately I gave a lot of it away and then I lost the 50' section I used for bear bagging so one of these days I'll buy some more.

Here are a few eBay listings for 1.9mm stuff. There's 150 feet for $30 or 1000 feet for $160.

have you inquired about buying a large amount from joe at zpacks?

Try searching for spectra bow lines.

These are often listed as pure spectra at around 175# breaking strength and about .030" diameter(just under 1mm if my math is correct.) Usually available in 45 yard spools.

This is braided line.

I have not, but I Joe is a good guy who could perhaps offer me a deal. I guess I was trying to find a manufacturer or wholesaler.

Hrmmm….1.27mm

goodboatgear.com has FSE Robline Dinghy Control 1.7mm for $0.16/foot

It's very nice line. Some of the other lines are very nice too, such as ZPack's.

Is the ebay stuff I posted above the correct stuff?

Perhaps you can find something Here.

Try Treestuff.com

hey, have you tried kite string for stunt kites or kite boarding kites? It is thin spectra, sold by test rating, in bulk. I don't have any experience with buying it so i can't recommend anywhere to get it, but if you google kite supplies you should be able to come up with a few suppliers of small spectra line. I wasn't able to find diameters on this stuff so not sure how big it is.

I think it's Q-Powerline Kite String. It's available in hi-vis yellow and this thread has some pics that looks very similar to the stuff I received:

I'll have to call the company to see how think their 200# stuff is.

Hey Bryce,

I always use Zing-it for bear bag, shelter line, etc…

It is thicker than what you are looking for.

Seems about perfect for everything I do, thick enough and enough slip for bear bagging and enough grip for a double taut-line hitch.

I find anything thinner hard to work with when my hands are cold.

I bought mine at:

http://www.rescueresponse.com

The site says it’s 2.2mm, but it appears to be more like 1.75mm. They had a bulk sale that was much cheaper than WesSpur at the time.

Note, it is not reflective. I prefer that myself as I sometimes have to stealth it.
