The strengths of poacher’s and scaffold knots vary depending on rope fibers, construction and diameter. Figure 8 Bend 19% 81% . The poacher’s knot is a loop made by tying half of a double fisherman’s bend (two wraps) and a scaffold knot is loop made by tying half of a triple fisherman’s bend (three wraps). The ratio doesn't change that much, so not much change in fall factor... Shunt should stay just as high.Well horses for courses, but remember that both knots can be tied incorrectly! Another factor to consider is how hard will it be to untie the knot once it has been loaded. Figure 8 on a Bight (aka Figure 8 Loop or Flemish Loop) This knot can be made anywhere in a rope by using a bight of rope and therefore doesn’t typically have to be at the end of a rope like some of the other knots. hey i am open minded here as its not one i have used before, and will not use until i see the reliable data etc, if it works for you then crack on!For an Anchor knot its the 9 or 8 bight depending on Anchor placement and the loading etc, again depends on many things.Put Scaffold knot's in each of the ends of the long lengths to make 2 long and one short.I think there is a bigger issue here!Some training centres (at least 1 that I know of), recommends technicians to use this knot (barrel knot) to minimize fall factor. On top of that it leaves more options open for how I can go about climbing in different situations. How true is this?You also get the same flattening of the inside of the loop with a fig 8 when its permanently rigged.id assume a cut to the alp anywhere, apart from loop, would compromise both legs?After much usage, the eye's intrados becomes flattened, significantly more than eyes formed by Figure-8 knots.It makes no difference in its minimum breaking load, always dress and set your knots.If you feel there is a significant risk of going onto one point of attachment using this technique (I.e when aid climbing) you can use the following method.Regardless of the knot type you choose to use, from an over hand to a barrel (scaffold knot) the residual strength in the rope is compromised so it comes down to the suitability of the knot for the intended task and not just as an anchor knot.Can be tied incorrectly (just like any knot) but is very hard to tell that the knot is tied in a dangerous manner without a real thorough pull on the knot and visual check.Tie an alpine Butterfly knot in the centre of the rope.Does anyone else out there have any input on this?The knot on your cows tail (device lanyard) is as important as any other and should be checked regularly, There are far bigger issues that present themselves to use at the moment in this industry like SIMPLE identification of Hazards to prevent anything happening to your ropes.Or this monster splice for your cowstails?1: Compact compared to others (fig 8)The Scaffold knot (known incorrectly as a Barrel knot) is the same as a figure of 8 on the bite in the terms the loop going round things.The damaged section is also diffuclt to inspect due to its position in the tightened knot.Figure eight on the bight for me. Double Figure 8 Loop 18% 82% . In some cases, a scaffold knot will provide an additional eight or more inches of travel in an MA by eliminating a carabiner and replacing a Figure 8 on a bight.A question that commonly comes up once the rescuer understands the difference between a scaffold and poacher’s knot is which knot should be used.
I have a hitch and a micro pulley to mind it on my cows tails. I've seen in some training centre's handout notes, recommending barrel knot instead figure-8, stating a reduction in fall-factor as reason...Personally, I find the Barrel Knot Eye a poor assembly to hold a carabiner or the attachment ring.Anyone more experienced have any more / better info ?Thanks you for a comprehensive reply, that will explain a lot to others - well done..!I would then have a Scaffold knot in each of the ends of my long lengths to make 2 long and one short.I would never tie Scaffold knots (barrels) round the main attachment ring of the harness as getting them off WOULD be problematic.When Inspecting Equipment, specifically ropes, you need to untie the knots to fully inspect them correctly.Some training centres (at least 1 that I know of), recommends technicians to use this knot to minimize fall factor.
This knot is not as well known or as universally used as the figure 8—many climbers may not know how to check the bowline. Its just to make it a little bit safer.I would tie two apposite overhand knots 2-6” apart from the centre of the rope.rarely see bunny 8s onsite.
