Step 3: Braid

The only difference to the ITS video is that you're doing the braiding on a larger scale. It will take a little while to get the hang of it, because the pairs of rope need to be aligned correctly, but once you've started, it falls in place quite nicely. Assign one person to braid and the other to support the rope and untangle the 8 strands behind the braider. I got given two 60 m ropes, which would have given me a fast rope about 10 m long. However, we don't have anywhere to hang a rope that long, so we just made it out of one 60 m length to make a 5 m climbing rope. The video below should give you a sense of how to do the braid - keep reciting "two under, one over" while remembering to wrap the strands carefully so the braid looks nice and neat.

Very inspirationsl! Do you have any pointers on how to start the braid? Or if you have a name for ge braid I can look it up myself?<br>Thank you! ??
<p>It's a 4 strand round braid. Check out the ITS Tactical link in the intro for more details.</p>
<p>Great tutorial, I used a load of old para cord and made myself a nice 2metre dog lead. everywhere I go I get comments about what a great lead it is. Super strong (big dog tested!) and never gets tangled. Just got another dog so am going to try a 'Y' shaped lead (2 dogs, 1 handle). I might even get the back splice for the handle right this time!!</p>
<p>Great idea. Would be overkill for our sheltie, though! :)</p>
<p>Perfect timing. I literally bought 2 retired 70 ft ropes last night from the indoor gym ($10).<br><br>2 questions: </p><p>If I have the time is a braided eye better?</p><p>What % of the original length will be lost when braiding? I'm using 8 strands like yourself. </p>
<p>The braided eye is better in the sense you don't need to buy a carabiner and it is stronger (it is the strength of all 8 strands rather than just 4, see Gunny Guy's comment below), but you sacrifice some length and technically it is more challenging to pull off (see the <a href="http://youtu.be/8rquCJRQY_4" rel="nofollow">ITS Tactical video</a> for a how-to). We found the final climbing rope to be about 1/12 the length of the original, but it also stretched a little (probably because it is hard to get a really tight braid). So I'd estimate you'd get 6-7 ft out of one rope and 12-14 ft out of two.</p>
Thanks for the reply. Not sure I understood your last comment about 6-7ft out of one strand and 12-14ft from 2. <br><br>
<p>You said you had 2 70 ft lengths; I was just guessing how long your braided rope would be if you used one of them or both of them.</p>
<p>Gotcha. Just to confirm. You're saying if I take both ropes and fold them in half so they are 35ft each I'll have about 12-14ft of climbing rope after braiding. </p>
<p>If you use a carabiner, you will have to cut each rope in half and pass each of these through the carabiner to make 8 strands for braiding, each of which will be about 18 ft long. Once you're done braiding, these will shorten to about 12 ft.</p>
<p>Got it. Ty.</p>
I wouldn&acirc;€™t necessarily say that the carabiner is the weak link in the system as the one in the pic looks like a Petzl William HMS witch is rated at 25kN (Around 2.4 tonnes) so would happily hold at least 5 people without any deformation. The weak link would be what it is attached to i.e. a tree.
<p>The carabiner itself wouldn't be, but the connection between the carabiner and rope is. It's probably worth noting that the rope has the strength of 4 strands, not eight. But that seems plenty strong enough.</p>
climbing ropes tend to have a guaranteed breaking strength of about 8kn but as the one in the instructions is fairly old I would put it at around 5 or 6 kn times by the 4 strands on the carabiner itself this would be around 20kn as a minimum. Not counting the weakness caused by the turns around the biner.
I had no idea they were that strong, good tip. Agreed, I wouldn't apply 25 kN to the tree!
Thanks for a great climbing rope tutorial. I made one last weekend for my daughter to help her with gymnastics. I used a 25KN Carabiner at the top and Gorilla tape at the bottom. 25 Feet when I started braiding, and 1 hr, 45 mins. later I had a 17.5 foot climbing rope. Total was about $35. Thanks again !!!
Thanks for the great instructable! I just finished my climbing rope for my daughter. It's about half as long as yours. Boy my hands are tired from the braiding but its a good kind of tired. Thanks again for the great idea.
How thick is the finished rope? <br> <br>Thanks <br>Totally doin this
Good question, I will update the instructable; it's 40 mm / 1.5&quot;.
I just really like that picture of the rope close up going all the way up to the tree.<br>
Hey, thanks. I'm glad I didn't lie on the wet grass squinting up the rope in vain... :)
Best use of old rope I have seen - Well done!!!
Thanks. Always fun to turn something marginal into something useful.
I use fire to seal the ends of my climbing rope (which I need to give some attention this summer, I haven't climbed since last summer... :\) but this is cool too, plus you still climb both. Thanks for the instructable!
I always get better results and neater ends when i use an old knife and heat it up with a blow torch to cut the ends. Then heat ends as you do to seal but when ends are near molten use greaseproof paper or new clothes tag (the glossy kind) and twist a rope in it folded over.
Good idea; sounds like a cleaner solution (provided you have a blowtorch, of course...).
A camping stove also works well (something like this: http://cascadedesigns.com/msr/stoves/rapid-cooking/pocketrocket/product )
Great instructable! May I add a summary and link to this Instructable:<br />http://www.instructables.com/id/Money-for-old-rope/
Thanks - and yes, of course... and now I have some more ideas about what to do with that extra rope I have.
