    Splicing Dynaglide into Amsteel? Combo whoopies..

    I'm looking at my Dynaglide whoopies, noticing them seperating quickly at the adjustable bury exit-much quicker than with Amsteel 7/64

    They aren't going to last long as I'm right on the weight limit at 220 lb but I like the thin cord, and its strong enough in all parts but the adjustable bury exit.

    My idea; make the fiixed bury and outer splice of the adjustable bury from Amsteel blue, then splice DG into that, above the adjustable bury and continue with DG to make a combination whoopie.

    This should give lower weight than full Amsteel, with a much strengthened adjustable bury exit.
    My concern is it being impossible to pass the straight splice of the DG/Amsteel into the adjustable bury for short spans and the Amsteel not gripping the DG

    Has anyone tried splicing Dynaglide into Amsteel 7/64


    Your thoughts and comments would be appreciated.

    Cheers, Pete.

    No sure about splicing the two together and have not tried it but I weigh 220 and have used a pair of dynaglide woopies for 2 years and did not have a problem with them. At the beginning of the summer I made a new pair just for fun by my old ones are still hang'able. Where the dynaglide exits the bury where the cord comes out it has loosened up and you can see the individual strands but I believe that is different from fraying (I remember talking to WV or maby Cranky Bear about this they explained it to me maby they will chime in) Cause all the fibers are still in tacked and not fraying but it has loosned up but when tension is put on the woopie they tighten right up, does that makes sense? Any ways if your fibers (individual strands are breaking or fraying) then I would say it is time for a new pair but if their just loosening up at the exit of where the cord comes out of I believe it is still usable. Do you have a picture that would be helpful. And I am no expert so please some one correct me if I am wrong. This is just from my experience.

    Dyneema is pretty strong stuff. Is there any fraying or is it just the strands separating? If the strands are intact with no wear, there shouldn't be any problems. The braiding at the bury exit tends to separate.

    With regards to splicing the two, I don't think dynaglide is big enough to give the amsteel something to constrict around. I could be wrong but intuitively I don't know if it is safe to do. I would liike to see if it's been tried or if it's possible.

    The difference between an amsteel whoopie and a proposed hybrid Dynaglide/amsteel whoopie can't be worth the effort I imagine.

    If you are talking about the strands separating I am not sure that it weakens them. I have a set of amsteel whoopies that have had a very large opening where the bury exits. I think they have been that way for most of the time i have been using them. If the strands are not breaking I think you should be OK. I am no rope expert, just going on what I have personally seen.

    Yes, that makes sense LRR. The strands are seperating, after 10 hangs I now have 1/2" of seperated threads, none are broken (yet).
    Thats interesting and good news about the seperating strands not weakening the cord, pure assumption on my part considered it to be weakened.
    At the same weight as you, I will probably have more faith in them now.

    As answered above, they are just seperating.
    I had a quick play after I posted and it seems the amsteel is having a hard time constricting against the thinner cord.
    As for whether its worth it I don't know but its good fun trying

    I've had similar experiences with Amsteel whoopies, but mine took a good few nights to start seperating. My last set were the worst and actually jammed up after 50 or so hangs.
    It hasn't bothered me with the Amsteel seperating as there is so much extra strength but with this scary thin cord, its making me think..



    Something I should have pointed out is I'm using a Dynaglide equivalent thats available in the UK. It has the same strenght and construction but is very slightly larger in diameter.

    My experience with Dynaglide is similar to what others have posted. The question of the strength of Amsteel or Dynaglide when the individual strands separate at the bury exit has been raised before, and someone posted that the word from one of the manufacturers was that strength is not compromised. Sort of vague, I know, but this (and the fact that I weigh 155 lbs.) has kept me using Dynaglide and Amsteel 7/64" interchangeably.

    Someone posted recently about the extra length of most whoopie slings not being used, with long tails hanging down most of the time. I've noticed that in my use, too, but haven't done much about it. One solution suggested was using a short whoopie sling and carrying one or two extensions that could be added as needed. If you did that, you could make the whoopies with Amsteel and the extensions with Dynaglide. That might save some weight and give you some peace of mind about the whoopie strength. I'm not sure what method of connecting a dynaglide loop to an Amsteel loop would be strongest, though. Also the extensions would need to be pretty long to make the combination lighter.

    Thanks WV, thats a very good idea with using shorter whoopies. It would give the benefits of a stronger splice with the lower weight of the DG loops.

    If the extension loops were the same length as the fully extended shorter whoopie , adjustment will be straightforward. (Edit; But no weight saving due to the splices. so no point in it)

    Food for thought WV and this would work well too with Dutch whoopie hooks.

    Great stuff

    One can minimize the strand separation by pulling the tail of the adjustable loop inline and parallel with the body of the whoopie sling. Pulling it outward at an angle can aggravate the separation.

    Otherwise idle time can be spent with a rounded pick loosening the strands in the densely packed area toward the portion with gaps between strands. Think of it as part of maintenance.

    Constantly loaded and unloaded dyneema-based line is used 24/7 in the fishing industry. It doesn't get retired for years. You can read Samson technical reports on it. I suspect we take loss of color and coating as signs of wear, when it isn't. Stroke the blue stuff and coloring comes off in your hands. Your occasional and short-term loading of <150lb / 70kg is well below a sustained fraction of breaking strength that will fatigue the cord out at 5000+ cycles.

    On shorter slings: Yes, you can minimize weight by making them so there's a minimum of length where the cord isn't doubled.

    You can make the accessory loops you carry out of 580-650lb Zing-It. If they're used as continuous loops, the load is carried on two legs. With appropriate caveats about the radius of larks head attachments..

    There's no reason not to splice any cords you like. Stitching to be sure the sleeve grabs the bury is easy.
