However, for Polyester, about half this length is sufficient. This is about three and a half full fid lengths (a full length fid is 21 times the rope’s diameter.) The very slippery Spectra and Dyneema require this long bury. Length of bury: Both Brion Toss and Starzinger recommend that the length of the buried tail should be 72 times the rope’s diameter.However, several requirements must be met to achieve both reliability and strength: Requirements: At first glance this seems to be a simple way of making an eye splice – just thread the end up the middle. The strength of the splice relies on the long tail being gripped by the standing end the strain is progressively transferred from the standing end to the two lines of the eye. When tested to destruction, the Long Bury splice should not be a weak point – the standing end of the rope may break first. Long Bury Splice technique: The animation shows how to tie a Splice using the Long Bury technique – with no “Lock”. However, both the Brummel Splice and the Long Bury Splice have a critical feature in common: they both derive their strength from the long buried tail. We prefer to reserve the name Brummel for the Locked Splice and use Long Bury Splice to describe this splice. Nomenclature: Some authors refer to this as a Brummel Splice without a lock. The short lengths were used here just for photography. Warning: in practice use a much longer tail and a more gradual taper – see below. The splicing technique described here imposes almost no kinking or compression on the rope’s fibers and breaking strains in the 90 – 100% range are to be expected. The ropes have impressive strengths but they also have impressive drawbacks: knots or kinks can reduce the breaking strain of some materials to a mere 30%. The loose weave results in the angle of the fibers being nearly parallel to the axis with minimal kinking. These ropes include: High-Modulus Polyethylene (HMPE), e.g., Spectra, Dyneema or Amsteel Liquid Crystal Aromatic Polyester (LCAP), e.g., Vectran or Aramid fibers, e.g., Kevlar, Nomex, Technora, or Twaron. Material: The Long Bury Splice technique is particularly suitable for un-sheathed, high modulus, loosely woven, 8, 12, 16, 20, or 24-strand, single braid ropes.
