Does anyone know or can refer me to the breaking strength of 1/8" and 3/32" nylon shock cord?Dec 9, 2010 at 5:39 pm #1672742Lawson KlineMember
I am not sure any company lists it. I have searched for it before with no luck. If you don't already own the shock cord I would suggest buying polyester stuff. It seems to be stronger and lasts a hell of a lot longer. Could be the reason its more expensive.
If you don't mind me asking. What are you doing with it?Dec 9, 2010 at 8:27 pm #1672795
I use it for two things. One is suspension cords for holding my under quilt against the bottom of my hammock. The other, I use a small loop of it at my tarp tie-out as a guy line tensioner.
I checked http://WWW.OWFINC.COM and they have the 1/8" polypro shock cord for $0.19 per foot which is pretty good!Dec 9, 2010 at 8:31 pm #1672796KatttMember
Did you sew a tab to your underquilt, like Shug? If so, how did you figure out exactly where it would be best to sew it? If not sewn on, how are you securing the cord onto the underquilt? I am trying to do just that right now. ThanksDec 9, 2010 at 9:11 pm #1672804Lawson KlineMember
1/8" shock cord works great with line locks. I use to sell them already made up on my website but they weren't hot sellers so I took them off. Just the other day I got two emails asking if I still sold them so maybe I should add them back? In any event here is a posting at hammock forums how I made them. The heat shrink tubing finishes them off.Dec 15, 2010 at 2:21 pm #1674520
I sewed small loops using a 2" length of 3/4" grosgain on the very corner of the tarp. The corner edges are re-enforced with 3/4" grosgain for about 4" (just the portion of the corner that is re-enforced with 2 extra layers of silnylon).
Then, I tied a 10" long piece of shock cord onto the grosgain tabs with a double fisherman's knot.Dec 15, 2010 at 2:50 pm #1674526John DonewarMember

Have you considered this arrangement?
The guyline limits the distance that the shockcord can stretch. I pitch the tarp and tighten the guylines until the shockcord is stretched out and the guyline itself is under tension. There is still stretch left in the shockcord after the guyline itself begins bearing the load.
As you can see I used a fisherman's knot to join the doubled over shockcord to the guyline. I don't even give it a second thought about it breaking. I believe my grosgrain tieouts would pull free first.

Great idea, Newton! I was always secretly worried about the integrity of the shock cord. This makes it a non-issue!
