Show off them splices

Woah.. lots of posts to catch up on..

Need to ask a quickie..
Why do i never see Tech 12 used in our experiments (100% Technora 12 strand)..

I'm trying to do an endless loop with a 8mm dmm fimble & Ice Tail... which is 8mm... it just ain't happening.. at least not with the length of the loop I'm trying to make (11-12in like the Ocean Dyneema Loop).. I need to use something like 1/4 or 3/16 to do it the way i want & the Tech 12 is much stronger than having to lose strength using Poly options in that size..

I remember seeing a member named Tuttle use small Vectran in small Fimble.

Is there a reason I've never seen anyone follow suit with Technora?
 
Is that really why though? The stuff I'm referencing is only a $1.50 tops.. depending on what size your working with... I'm talking about niche circumstances where you need smaller cordage but can't afford the strength loss you would normally get with a polyester product that small..

Like the example in one of my last posts, trying to splice a 8mm DMM Thimble into a short 11-12inch endless 12 strand loop.. you can't go small enough with poly to allowing the splice to pass through the thimble while still retaining the strength you want. However, a 1/4 - 3/16 technora or vectran peice of Cordage probably will..

As far as coated Vectran & Technora go, which of those two will pick less & which if the two have a better tolerance for bending. I keep reading conflicting information on them.. one description will advertise having the best bending ability & the next one will say the the same for the other cord. Then i once heard someone mentioning how making a ultra sling out of icetail was bad juju.. "cuz the fibers don't like being bent".. so they were obviously referencing the technora side of it..

There's some interesting Cordage's I've come across too recently, where they are described as being "designed" for constant diameter endless loops.. i might have already mentioned that though in another post, i can't recall.. Marlow Furler MPG 50, Marlow Excel Control (low mbs though), Gleistein Runner Twin (two cores). I've been trying to find some breaking strengths for these in a spliced loop configuration but can't find any.. seeing as they are designed with sacrificial cores, it would be interesting to know whether they retain better strength than normal when doing a continuous diameter style loop splice.

@Brocky Here is video with Sailrite showing off the method. (I'm referencing the pulling of the single core strand and single sheath strand for whipping later. Neat trick)

Interesting, but some of what he does is not a good example for people who are splicing arborist climbing lines. Mainly I am talking about the fact that he does not reduce the volume on the end of the core before he pulls it thru the cover. That works fine for loosely braided rope like the one he is splicing, but is a recipe for misery on most tightly braided climbing ropes. In addition, I would never abuse the snare on a Toss Wand trying to pull the core thru on a double-braid arborist's climbing line. A wire fid or a Marlow needle is a much better tool because you are going to have to pull hard to get the core through, and that will destroy the snare on a Toss Wand. Plus, I never bother sewing the crossover on any double-braid splice. If you get the crossover nice and tight and keep tension on both sides of the rope during the bury sewing is just a waste of time.

Interesting videos.. I FFW through most of it as it a pretty slow going.. but what i did see, kinda stuck out like a sore thumb.. In this video he's saying to milk the slack out of the eye in the opposite direction I've always heard to go.. & when he jams that awl through the eye after doing so & yanks, I'm pretty sure all that slack just got stretched out & ended up back where it was to begin.. Not only that but everything is stitched in place at the x-over. That eye slack needs to go the other way, back into throat & into the rope somehow.. & even then it doesn't "always" work if things are unaligned/unequalized to begin with.. I always milk from X-over to throat right from the start of burying, that way if you have to, your not trying to do it all at the last minute. Idk.. Idk.. I'm still trying to wrap my head around that awl thing he did... he has to have gotten it from somewhere & i just can't see how it does anything but distort the core underneath when it's all stitched 2 inches up from there.. I'll have to see what it does, if anything in person. Personally, it just looked like the slack went right back to the other side.

Also, he would have had alot easier time running it home had he not kept inducing twists into the line every time he needed to loosen the throat.. In order words, every time he thought he was loosening things up, he was in reality adding another twist & making it that much harder to pull cover towards him, binding everything up.. In general, when done correctly, those poly & nylon boat lines bury themselves.. at least the ones I've done have.

Then of course he wasn't aware he couldn't yank on his connection that hard without losing it suggests he doesn't do this very often.. IDK.. it seemed like amateur hour & struck me as odd because Sailrite isn't some new company with a bunch of noobs.. There a legit portion of the sailing industry.

I agree. This guy barely knows what he is doing, and has obviously never spliced a tightly braided arborist's rope. Plus, it takes him forever to get to the point. I got bored about 2 minutes in.

Hahahahaha.. i wanted to say that so bad.. but couldn't allow myself to considering some of the splicing questions i was asking 8 months ago..lol.

I think skygear must have a fetish for amateur splicing porn..lol.. it's ok sky.. we all have our demons.. keep tagging..
 
When I'm splicing, or sewing like today, or crafts in general - I'll pull up a YouTube video and just let it auto play whatever YouTube feels like throwing in the mix. If someone was enthusiastic enough to put a video out there and the time it takes to make one and edits I'll let it play. Again I agree with you folks, not the best video out there. On the other hand, he did do one thing that no other videos I've seen have done. And that is using a strand from the core and the strand from the cover as whipping twine. As mentioned above I have done that for years myself, just never seen it demonstrated in a video. Not to mention the year on that video, it's old!

Ahhhhhh there we go... Right on cue... The addiction denial.... We are not judging you man.. we know it happens.. we are here to support you.. this is your "safe space"..
 
Speaking of addiction, I wasted 2 hours today trying to do another eye splice in Vega. This time I got everything done just right except that when I was done there was a little tiny bit of core strand peeking out of the throat of the splice and no matter how I massaged, milked, beat, and pulled on the damn thing it would not bury. So far I have been unable to get consistent results with Vega eye splices and I am about ready to toss in the towel and just use it for SRS without a spliced eye. I can't trust an eye that is not fully buried.

HoHoHo...! Maybe Santa Brocks could give you some pointers on it.. I've personally haven't done anything Marlow brand yet as their splice instructions seem tough compared to stateside manufactureres..

However i am planning on it as i have some 9mm rit & i believe Brock mentioned a certain Marlow splice being the only one compatible or something like that..

What instructions were you going by anyways? If applying USA instructions, have you tried going heavy on the tapers.. like long & gradual?

I'm with ya in wasting time though.. i came up with this the other night.. On a gamble I went & snipped a useful length of Ice Tail in half to make it.. turns out i couldn't splice it the way i wanted to (talked about it in earlier posts).. & now i go throw it on the smallest Cordage i plan on using it with & I'm like 1/2in short on length.. just a smidge too short to be useful.. i was shooting for snug but this is too snug.. that & it enlarged too much.. going to try 1/4 hollow braid next.. well see what happens.. Hopefully i can get full buries all the way around.

The only suggestion for the Marlow splice is to try forcing the cover on the eye into the throat. I remember having problems with that to cover the throat opening.
The Marlow splice is fairly long, too long for a hitch cord, if that is what you were planning for the RIT.

I am using the Marlow instructions for splicing Vega (available on their website). I have been following the instructions to the letter except that I have played around with doing the cover taper a little closer to the throat to make the bury easier. If you have never done one of these they are a very different beast. There is no crossover, just the tapered core and cover tails pulled down into the rope over the top of the existing core. It gets tighter than hell in there which makes the buries really difficult. Not a fun splice to do.

Yeah, I have not completely given up on it. Will poke and prod it some more today.

Success. Not quite as tight as I wanted it but best Christmas present I got all day!

Ooooooo Arlo! That's looking kinda fancy pants!!

I haven't seen or read about the construction of the Vega but.. i wonder why you have to splice it like that.. That definatley sounds like a bear.. especially if the cover is a tight construct..

I wonder if you could do a normal be DB Splice with it..

Just a heads up..
Gleistein Ropes has killer splicing instructions for all sorts of different constructions & braids..

Vega cannot be spliced with a double-braid splice because the construction is more like a kernmantle. It has a braided cover around a core that consists of 8 internal linear strands, each of which is wound from three smaller strands. Thanks for the tip on Gleistein Ropes. And Merry Christmas!
 
When doing the Vega splice, do you bury the core and cover on the same side, or one on each side of the core? The instructions visibly get confusing from step 7 onward.

First I bury the core and then I bury the cover right on top of the core, both on the same side. But I am not sure if it matters. They could definitely do a better job with their instructions.
