are there tips on breaking in new i2i friction cords?

[voxac30dude]

just wondering if you can give me some tips on breakin in new friction cords. i currantly but i2i beeline from wesspur.com and am kinda frustrated with the eyes them self being soft and when you put a caribiner through the hole it snags a few fibers. are there any ways to get the eyes to be alittle stiffer?

None that I know of.

Beeline is core dependent rope, so the cover is not really where the strength is. The locking brummel splice prevents including the cover into the eye portion. The core is light and fluffy, so it seems at risk for snagging and damaging.

I find that my home-made splices in beeline settle into a pretty tight eye with a little bit of use, and I generally don't untie the friction hitch very often. It's easy to detach from the belt and leave on the line.

If you really wanted it to be a tighter eye, it probably wouldn't hurt anything to wrap some whipping string around the eye to hold it in a tight loop. Waxed nylon string would probably make a dandy whipping that would be almost invisible, yet remain pretty tough to abrasion and snagging. It would take a great deal of patience to make that many loops through the eye, though.

Dip the eyes in 3M Scotchkote( Electrical Coating) and let dry some of the makers do this at the time they are Braiding them

I love the 10mm beeline eye to eye prusik. What kind of carabiners are you using? I never had a problem with the Petzl's since they have a smooth nose designed specifically so that it won't snag on anything.

i use climb right large D and climb right HMS bent pear caribiners.

I see everyone going to Braided Eyes, have you noticed that the Braided rope forces you to start the friction hitch after the thick part of the eyesplice. If you just tie an Double Fishermans knot instead of the Spice it will have the outer Case of what ever line you prefer, the knot ed Eye will exspand for diferent Biners, you can start your friction right after the Fisherman's knot to keep it in close and last you don not have to Pay for Splicing$$ you just buy how ever many feet of cord you want and tie them up as long as you need and or want, just a thought from the old school

When I splice mine, I finish by whipping the eyes with waxed thread. Basically gives a protective wrap to the core. Also tightens them up a bit if they're loose. Others have used beeswax, and I think one of the rope manufactures even makes a product just for it, although it's a bit pricey if you aren't doing a bunch of them.

i allways thought that I2I cords are stronger then tying fishermans. doesn't the knot lower the breaking strength?

 

[pdqdl]

Yes it does, but so what? A Beeline I2I will have double the strength of a single line. At 6000 lbs breaking strength single line, doubled to 12k, then rated at only 50% of original breaking strength because of a double overhand knot (double fisherman's done only once) rather than a splice: you are still WELL within safety guidelines.

In fact, your body will probably be torn in half by the stress of a fall that could break that rope. If it fails under load, you will probably not ever know about it, because you will break before the rope does.

I suspect that beeline would choke down and sever the climbing line before it failed on an eye-to-eye friction hitch. It has remarkable heat resistance not found in climbing line.

Of all the events listed in the injuries forum, I don't think I have ever read about an equipment failure that wasn't related to being cut with a chainsaw or breaking under questionable conditions.

I hate b-line, it is way too mushy. That's a technical term BTW

I'll stick with some 3/8 double-braid and fisherman hitches.

Actually, most i2i's are "spliced" using a short bury and a locking brummel. It's not a full splice with a long, tapered bury like you think of as being significantly stronger than a knot. The difference in strength between that and a double fisherman's is really negligible. They're both plenty strong like pdql said. In fact, search for moray's post(s) last fall on the subject. He did quite a bit of testing on different splices and knots, breaking a lot of tenex and beeline in the process.

I find knots just more in the way, but then again, the thicker section near the eye where the bury is on an i2i has its drawbacks too. If I didn't splice my own and had to pay $30+ for one, I'd be tying knots.

Just my 2 cents.

Regarding the strength of the Double Overhand Knot (Double Fisherman's)

This knot testing article pretty much tells you to use the DOK over other popular knots for your hitch cord, although it does not compare it to a splice. It only puts strength loss at 5% for a slow pull to failure!

Even though the test is flawed in ways explained by the author, that is a whole bunch stronger than we usually give it credit for.
